High School Sophomore Math Curriculum and Course Study

The standards for mathematics education per grade vary by state, region, and country. Still, it is generally assumed that by the completion of the 10th grade, students should be able to grasp certain core concepts of math, which can be achieved by passing classes that include a complete curriculum of these skills. High School Sophomore Level Math Courses Some students may be on the fast track through their high school math education, already starting to take on the advanced challenges of Algebra II. The bare minimum requirements for graduating 10th grade includes an understanding of consumer maths, number systems, measurements and ratios, geometric shapes and calculations, rational numbers and polynomials, and how to solve for the variables of Algebra II. All students are expected to understand these concepts at this level. In most schools in the United States, students may choose between several learning tracks to complete the prerequisite four math credits needed to graduate High School. Math classes build upon each other, so each subject must be completed in the order they are presented: Pre-Algebra (for remedial students), Algebra I, Algebra II, Geometry, Pre-Calculus, and Calculus. Students must reach at least Algebra I before completing 10th grade. Different Learning Tracks for High School Mathematics Every high school in America does not operate in the same way, but most offer the same list of mathematics courses that sophomores in high school can take in order to graduate. Depending on the individual students proficiency in the subject, he or she can take the expedited, normal, or remedial courses for learning mathematics. In the advanced track, students are expected to take Algebra I in the eighth grade, allowing them to start Geometry in ninth grade, and take Algebra II in the 10th. Meanwhile, students in the normal track start Algebra I in ninth grade, and typically take either Geometry or Algebra II in 10th grade, depending on the school districts standards for math education. For students who struggle with math comprehension, most schools also offer a remedial track that still covers all of the basic concepts students must comprehend to graduate high school. However, instead of starting high school with Algebra I, these students take Pre-Algebra in ninth grade, Algebra I in 10th, Geometry in 11th, and Algebra II senior year. Core Concepts Every 10th-grade Graduate Should Grasp No matter which education track they are on—or whether or not they were enrolled in Geometry, Algebra I, or Algebra II—students graduating the 10th grade are expected to master certain mathematics skills and core concepts before heading into their sophomore years. Proficiency must be displayed with budgeting and tax calculations, complex number systems and problem-solving, theorems and measurements, shapes and graphing on coordinate planes, calculating variables and quadratic functions, and analyzing data sets and algorithms. Students should use appropriate mathematical language and symbols in all problem-solving situations, and be able to investigate problems by utilizing complex number systems and illustrating interrelationships of sets of numbers. Additionally, students should be able to recall and use primary trigonometric ratios and mathematical theorems like the Pythagorean to solve for measurements of line segments, rays, lines, bisectors, medians, and angles. In terms of geometry and trigonometry, students should also problem-solve, identify, and understand common properties of triangles, special quadrilaterals, and n-gons, including the sine, cosine, and tangent ratios. Additionally, they should be able to apply  Analytic Geometry to solve problems involving the intersection of two straight lines, and verify geometric properties of triangles and quadrilaterals. For Algebra, students should be able to add, subtract, multiply and divide rational numbers and polynomials,  Ã¢â‚¬â€¹solve quadratic equations and problems involving quadratic functions. Furthermore, sophomores must be able to understand, represent, and analyze relationships using tables, verbal rules, equations, and graphs. Finally, 10th graders must be able to solve problems that involve variable quantities with expressions, equations, inequalities, and matrices.

The Head of Poseidon - 1339 Words

The Head of Poseidon Greek mythology is thought to be very fascinating to many people; I personally wanted to learn more about it and the Hellenistic period. A new cultural age was led by Alexander the Great when he took over Egypt and the Near East, historians refer to this period as Hellenistic. The Hellenistic period started when Alexander died in about 320 BCE and continued approximately three eras, pending the dual killing of Queen Cleopatra of Egypt and her Roman partner Mark Antony in 30 BCE after their pivotal overthrow at the combat of Actium by Antony’s opponent Augustus. During that time, Augustus made Egypt a jurisdiction of the Roman Empire. The cultural centers of the Hellenistic period were the court cities of the Greek†¦show more content†¦Then from time to time, when he was in a corrupt mood, Poseidon would attack the ground floor with a trident and cause disruptive earthquakes, drownings, and shipwrecks. Poseidon was comparable to his brother Zeus in utilizing his power on women and in portraying masculinity. (Kleiner, 123) He had several love affairs and engendered various children. Poseidon on one occasion married a Nereid, Amphitrite, and formed Triton who was half-human and half-fish. He also impregnated the Gorgon Medusa to give birth to Chrysaor and Pegasus, the flying horse. The rape of Aethra by Poseidon stemmed in the delivery of Theseus; and he changed Caeneus into a man, at her request, after raping her. Another rape involved Amymone when she tried to escape from a satyr and Poseidon rescued her. Other descendants of Poseidon include: Eumolpus, the Giant Sinis, Polyphemus, Orion, King Amycus, Proteus, Agenor and Belus from Europa, Pelias, and the King of Egypt, Busiris. One of the most disreputable love encounters of Poseidon includes his sister, Demeter. Poseidon chased Demeter and to escape him she turned herself into a mare. In his lust for her, Poseidon changed himself into a horse and took her. Their encounter resulted in a horse offspring, Arion.

Is Vaccines A Medical Invention - 1577 Words

Introduction Vaccines are considered to be a medical invention that has eradicated diseases like measles, rubella, and whooping cough and prevented people from suffering devastated symptoms (Chatterjee O Keefe, 2010). Even though it is a great medical invention, today there is diminished trust by parents, couple with their concern of its safety. Parents are concern that thiomersela component that contains mercury in vaccines, causes autism (Center for Disease Control and Prevention [CDC], 2013 b). Even though scientific evidence shows there is no relationship between autism and vaccine (CDC, 2013 b). Parents are stating it is their autonomy to protect their children from unsafe drugs. However, the government and public health workers don’t share the parents’ views. This has gotten a lot of attention due to the recent out breaks of measles at Disney Land and the return of whooping cough. Vaccinating children protects them from suffering devastating disease and protect t he community at large. Since the discovery of vaccines in the 20th century, today’s parents, government, and public health workers have limited or no experience of the devastating effects of polio, smallpox, or measles (Chatterjee O’Keefe, 2010). Parents claim the right of autonomy to opt out of vaccination that has led the government to taking a paternalistic approach to protect the right of community.

The Boy Who Was Raised By Bruce Perry - 1381 Words

In The Boy Who was Raised as a Dog author Bruce Perry demonstrates how understanding the brain’s inner workings and development can help bring traumatized children from heartbreak to hope, while always balancing that hope with caution. In his book Perry illustrates how empathy is vital to healthy child development. There has been a decrease in the amount of healthy adults involved in a child’s life than in decades before. Families are smaller, teacher to pupil ratio has increased, and so the number of human-to-human interactions where children are being taught and nurtured has suffered. If you are an adult who is involved with children in your daily life, parent, teacher, law enforcement, etc., and you know that a child has been exposed to something that is potentially traumatic the first thing you should be aware of is that not all traumatic events automatically lead to disastrous mental health outcomes. In fact the majority do well, but for these successful outcomes t hey do need your attention, support, and awareness. What makes children get better following a trauma is connection with other human beings. Connections to people who are kind, patient, present, but not necessarily psychologically insightful, is at the core of a successful therapeutic relationship.

Dna And Forensics Essay Example For Students

Dna And Forensics Essay What is DNA? DNA (noun) First appeared 1944 : any of various nucleic acids that are usually the molecular basis of heredity, are localized especially in cell nuclei, and are constructed of a double helix held together by hydrogen bonds between purine and pyrimidine bases which project inward from two chains containing alternate links of deoxyribose and phosphate. What is forensics?fo*ren*sic (adjective)First appeared 16591 : belonging to, used in, or suitable to courts of judicature or to public discussion and debate. 2 : ARGUMENTATIVE, RHETORICAL. 3 : relating to or dealing with the application of scientific knowledge to legal problems *~ medicine* *~ science* *~ pathologist* *~ experts*.1 How are the two related?DNA can be used to identify an individual. In relation to forensics, when there is a crime investigation and some proof is needed to back up the suspect DNA is usually the way that scientist deal with the situation. Specialized forensic scientists scan about ten DNA regions that vary from person to person and use the data to create a DNA profile for that individual. This is effective because there is a very small chance that another individual has the same DNA profile in the same set of regions. DNA can be used for many other things besides for committing a suspect. It can also free a person wrongly accused of a crime, identify crime and catastrophe victims ,establish paternity and other family relationships ,detect bacteria and other organisms that may pollute air, water, soil, and food ,and even match organ donors with recipients in transplant programs . How effective is DNA in identifying a person?DNA identification must be used intelligently. When you find a certain thing through DNA at a crime scene that thing alone may not be enough. However if many little things are found then you can connect them all and find what you need. If the first thing you find is found in almost half of the American population that is not very helpful but if you keep on finding more and more things eventually it is narrowed down to one specific person. Once the DNA is found how is it typed up?Only one-tenth of a single percent of DNA makes one person different from the next. Scientists can use these variable regions to create a DNA profile for a person, using samples from hair, blood, bone and other body tissues and products. Generally in criminal cases this involves getting samples from crime-scene evidence and a suspect giving off some DNA, and analyzing it for the presence of a set of specific DNA regions. Scientists find the markers in a DNA sample by designing small pieces of DNA called probes that will each seek out and tie to a complementary DNA sequence in the sample. A series of probes tied to a DNA sample creates a unique pattern for an individual. Forensic scientists compare these DNA profiles to the suspect’s sample to see if the suspects sample matches the evidence sample. If two samples are alike at four or five regions, most probably the suspect contributed his DNA to the crime-scene evidence, though there is a slim chance that someone else has the same DNA profile for a particular probe set. The question is how small of a chance must there be when convicting the guilty or the vindication of the innocent lies in the balance? The judges often let the jury decode based on this and other evidence involved in the case. Experts say that using DNA forensic technology is better then eyewitness accounts. Sources of DNA for testingBlood –Once bloodstains are found an analysis can most probably be made. But it depends on the surface or substrate on which it is found. If the blood is found on glass, metal, hard plastics or lightweight cloth it is easy to extract the blood and analyze it. If found on other dense and heavily colored fibers a few additional steps are required. Soil and concrete are almost impossible substances and surfaces because it is so hard to extract the blood from them. From the blood it can be figured out if the bloodstain is from a male or female. It can also tell us how many people it involved for a DNA profile of two people is far more complex then a DNA profile for one person. Specimens that are drawn from the victims or suspects are called known exemplars. They usually consist of liquid blood. The best storage for blood is frozen. Buccal or the inside of your cheek can also be supplied as exemplars. For people who cannot have blood drawn for any particul ar reason it is used instead of blood. Semen- Semen stains are the most common evidence to be submitted for DNA analysis. Sperm cells and non-sperm cells can, as well as blood, be separated. Tissues –Isolation of DNA from tissues is a simple straightforward process. Usually, soft tissues received in the laboratory are from partially decomposed bodies. DNA last shorter in liver and kidney, longer in muscle and brain and even longer in dense bone and teeth. Sometimes DNA can be drawn from a bullet or weapon used to injure the brain or any other tissue. If a body is not recovered and only bits of tissue are then they can be used and compared with surviving family members. .u56160f765e45c5e933dbf01755888792 , .u56160f765e45c5e933dbf01755888792 .postImageUrl , .u56160f765e45c5e933dbf01755888792 .centered-text-area { min-height: 80px; position: relative; } .u56160f765e45c5e933dbf01755888792 , .u56160f765e45c5e933dbf01755888792:hover , .u56160f765e45c5e933dbf01755888792:visited , .u56160f765e45c5e933dbf01755888792:active { border:0!important; } .u56160f765e45c5e933dbf01755888792 .clearfix:after { content: ""; display: table; clear: both; } .u56160f765e45c5e933dbf01755888792 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u56160f765e45c5e933dbf01755888792:active , .u56160f765e45c5e933dbf01755888792:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u56160f765e45c5e933dbf01755888792 .centered-text-area { width: 100%; position: relative ; } .u56160f765e45c5e933dbf01755888792 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u56160f765e45c5e933dbf01755888792 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u56160f765e45c5e933dbf01755888792 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u56160f765e45c5e933dbf01755888792:hover .ctaButton { background-color: #34495E!important; } .u56160f765e45c5e933dbf01755888792 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u56160f765e45c5e933dbf01755888792 .u56160f765e45c5e933dbf01755888792-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u56160f765e45c5e933dbf01755888792:after { content: ""; display: block; clear: both; } READ: Smoke Free Restaurants EssayChemically Treated Tissues-There are two common chemical treatments, formaldehyde for medical purposes and embalming. DNA can be drawn from both tissues. Even bodies that have been buried for several years can give results. Hair Roots- The sufficient amount of hair needed for analysis is one to five hair roots. Shed hairs contain only traces of DNA and are generally not suitable for testing in forensic use. A highly specialized method known as mitochondrial sequencing is starting to be used more and more. Saliva- DNA can be taken from saliva deposited on almost everything. Envelope flaps or stamps, as was done in the New York World Trade Center bombings. It can also be drawn from cigarette butts, cups, bottles, telephone mouthpieces and bite marks found at crime scenes. Urine –DNA sampling from urine is not very common. Since healthy individuals do not shed nucleated cells into urine. Conventional testing is more likely to give results and is used to test for drug use. Products of Conception- When a teenaged girl has been impregnated by a relative or other adults the non-living product must be analyzed. As well as in a rape or anything resulting in pregnancy. How did the forensic use of DNA start?Alec Jeffreys , a geneticist at the University of Leicester in Britains Midlands, started forensic use of DNA. He invented the techniques that took human identification from the laboratory to the courtroom in 1984. He called the process â€Å"DNA fingerprinting† which is not used by most forensic scientists because it can be misleading. He applied his techniques to an immigration case. A boy from Ghana wanted to emigrate to Britain, claiming his mother was already a resident. A DNA analysis showed that the two were in fact related and the Home Office put its stamp of approval on the new technology. Science Essays

Shaolin Soccer Physics Analysis Essay Example For Students

Shaolin Soccer Physics Analysis Essay In this scene, the soccer ball was kicked by a player with a tremendous force. The Lightning hand Goalie (Forth Brother) stops the ball, but fly back because of the reaction force. This scene is an example of bad physics because it is unrealistic that a human can actually take off/fly after been hit by a soccer ball. Let us assume the following:-A soccer ball is usually weight 15 pounds = 0. Egg in Fife games -We cant simply calculate the velocity of the ball that the guy kicked in the movie. So I used the world record for the hardest recorded shot in Soccer. Which is MPH = 50 m/s, reformed by David Hirsh in finding how long a soccer field is and the time traveled -the official length of the soccer field is mm long. The guy who kicked the ball stands right between the half line and the penalty area, so about a quarter of 90 m, which is 22. 5 mom. 5/50=O. SMS=O. Skit=O. Sops=mm/spins the amount of force acting on the person by the soccer ball=delta v/defect=ma -?44. 4 NON. N is about the same as holding an object that is 4. Egg. So in real life, if you kicked a ball at someone with the same force as the world record of hardest soccer ball kick, this eight be able hit someone and make them step back or sit down; but certainly it ¤? ¬was not enough force to knock a person 10 feet above ground. -Len addition, if you look at the beginning of the scene; when the guy kicks the ball and the ball was flying towards the net, there was no sign that the ball was affected by the f orce of gravity. In this scene, the Shallow team has Just found their inner gung-if by beating the group of thugs and is now playing their first important match. Sing uses his powerful leg to score and immediately gets a goal. How about the physics? Well, as you can see n the clip, when he kicks the ball it looks like he exerts quite a bit of force. However, when he scores the goal the net does not even move an inch. The net should have moved to imitate the reaction force of the ball acting on the net. Instead the force of the ball traveling towards the net did not have any effect. Lets assume that Sing has used the average kick of a professional soccer player, which means the ball is traveling at approximately 30 m/s (1) and that the soccer ball is the average mass of a size 5 outdoor soccer ball, which is approximately 0. 43 keg(2). To find the force of he ball acting on the net, let the time of the ball traveling be 2. 0 condensate=AMA=VA/defect=O. 43(30/2. O) = 6. Interferer, the ball should have exerted enough force to move the net backwards with the exact amount of force from when the ball hit the net if it were to apply to Newton ¤? ¬was third law which states that for every action, there is an equal and opposite reaction. (3) Instead the ball stayed spinning and the net did not look like it was moving at all. Len real life, if the ball were to hit the net with the amount of force that Sing exerted, the net would have harassed violently and the ball would have hit the gr ound immediately right after because of the force of gravity acting on the ball. When another guy throws a soccer ball at Steel Leg, he kicks it back to him with tremendous force. The ball hits the man in the stomach, propelling him backwards, into a roll, and continuing to slide for a couple of feet. From the far shot, one can estimate that the 160 lbs man flew about a total of 30 feet. Its a little hard to tell the acceleration from the film because the shaky camera follows the man flying, but the background moves about roughly about e got hit by a train. .u13fdfec06d5a30cb69e1d8c960d9e50c , .u13fdfec06d5a30cb69e1d8c960d9e50c .postImageUrl , .u13fdfec06d5a30cb69e1d8c960d9e50c .centered-text-area { min-height: 80px; position: relative; } .u13fdfec06d5a30cb69e1d8c960d9e50c , .u13fdfec06d5a30cb69e1d8c960d9e50c:hover , .u13fdfec06d5a30cb69e1d8c960d9e50c:visited , .u13fdfec06d5a30cb69e1d8c960d9e50c:active { border:0!important; } .u13fdfec06d5a30cb69e1d8c960d9e50c .clearfix:after { content: ""; display: table; clear: both; } .u13fdfec06d5a30cb69e1d8c960d9e50c { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u13fdfec06d5a30cb69e1d8c960d9e50c:active , .u13fdfec06d5a30cb69e1d8c960d9e50c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u13fdfec06d5a30cb69e1d8c960d9e50c .centered-text-area { width: 100%; position: relative ; } .u13fdfec06d5a30cb69e1d8c960d9e50c .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u13fdfec06d5a30cb69e1d8c960d9e50c .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u13fdfec06d5a30cb69e1d8c960d9e50c .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u13fdfec06d5a30cb69e1d8c960d9e50c:hover .ctaButton { background-color: #34495E!important; } .u13fdfec06d5a30cb69e1d8c960d9e50c .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u13fdfec06d5a30cb69e1d8c960d9e50c .u13fdfec06d5a30cb69e1d8c960d9e50c-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u13fdfec06d5a30cb69e1d8c960d9e50c:after { content: ""; display: block; clear: both; } READ: Christians and The Environmental Ethics EssaySomehow in the next scene, the ball is seen moving horizontally when Steel Leg Jumps up into the air and kicks it downward. The ball curves and hovers over the ground, ripping apart large chucks of grass, dirt, and its so powerful that it pulls the thunderclouds in. The ball cyclones and carries people in its vortex, and as the goalie sees it coming, it rips off his clothes and carries everything into the goal, destroying its posts. According to destruction path of the end shot, the goal was made from 3/TTS of the field. There is one action that is concurrent with real hicks: when masses are unequal, the momentum of the smaller mass can multiply via a slingshot effect; however, the power to generate such a force as to change weather must have had some kind of impact on his leg. The reason you cannot do those things is because of the theories of force and momentum. Use the Newtonian laws for force to explain why you cant do that. The equation is F=m*a which is force equals mass times acceleration. The reason that you cant knock a person over with a soccer ball is because it doesnt have a substantial amount of mass and that no tater how much force you put into the soccer you wont knock a person over a Just 20 feet acceleration formula is a= Volt which is the change in velocity over time. So the father it is the faster the acceleration, for example if I fire a soccer ball 100 yards away from a person from a cannon Ill definitely knock that person down because of the force increase so the momentum increases. The momentum formula is P=F*d which is momentum equals force times distance so thats why it couldnt knock anyone over because it couldnt have generated enough force and momentum to knock anyone down from Just 20 feet from a human kick, the kick doesnt even enervate a enough force to gain enough force to knock a person down. Now for the 20 foot Jump in the air, have you ever heard the gravitational constant be 9. 81 m/SAA. Let is the average cal. Constant for gravity on Earth. There is no way a human can Jump that high because this means the force of gravity equals the universal gravitational constant (which 6. 63*AAA-11) times the mass of the object times the mass of the planetary object(the mass of Earth is by the center of distance squared. The person thats trying to jump that high must have a stronger force upward than the force of gravity downward. To achieve this the person would have to had lived on a planet at least three times the gravity of Earth(lets say 1 g=9. 81 N). Multi ply that by three and theyll be able to Jump 20 feet in the air, but since thats highly improbable thats impossible. Due to his Shallow Training, he is able to kick the ball so high that it disappears from the naked eye and stays in the air for over an hour. When the ball hits the ground, it exerts its force on the ground, which is such a large mass that it does not move but exerts a reaction force onto the soccer ball, causing the soccer ball to bounce back into the air. The soccer ball loses some energy from friction, but reaches no more than 12 feet in the air and stays in the air for less than 2 seconds on the second bounce. The soccer ball is an elastic object with an estimated coefficient of restitution of height loss to be between 40%-60% with each bounce. Even if the soccer ball bounce was calculated at the higher height loss of per bounce, with this calculation it would mean the first kick only reached 30 feet height (fit / 0. 4) and was portrayed to have stayed in the air for over 60 minutes. This inconsistency demonstrates that the shallow powers of the Mighty Steel Leg applies only to the initial force exerted on an object but loses its power in the reaction force. .ud5b6c98c8e3c092a7df6d3460cbb4c8e , .ud5b6c98c8e3c092a7df6d3460cbb4c8e .postImageUrl , .ud5b6c98c8e3c092a7df6d3460cbb4c8e .centered-text-area { min-height: 80px; position: relative; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e , .ud5b6c98c8e3c092a7df6d3460cbb4c8e:hover , .ud5b6c98c8e3c092a7df6d3460cbb4c8e:visited , .ud5b6c98c8e3c092a7df6d3460cbb4c8e:active { border:0!important; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e .clearfix:after { content: ""; display: table; clear: both; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e:active , .ud5b6c98c8e3c092a7df6d3460cbb4c8e:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e .centered-text-area { width: 100%; position: relative ; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e:hover .ctaButton { background-color: #34495E!important; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e .ud5b6c98c8e3c092a7df6d3460cbb4c8e-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ud5b6c98c8e3c092a7df6d3460cbb4c8e:after { content: ""; display: block; clear: both; } READ: Standardized Testing EssayIn another example, when the Shallow Soccer Team goes against the Demon Soccer Team in the finale match, the Action-Reaction Principle is overpowered by the power of American Drugs for the Demon Team athletes. When Mighty Steel Leg attempts his third goal at the Demon goalie, the CGI portrayed the ball to travel about 15 inches per frame, which is estimated to be 20 MPH. The CGI special effects portrayed the soccer ball to break through the atmosphere, changing the atmosphere colors into the shape of a Puma, indicating its high speed. The Demon goalie not only stopped the ball, he grabbed it with both hands without bending his elbows or moving any other parts of his body. Although the ultra-fast soccer ball appeared to cause no damage to the goalie, the impact of the soccer ball seemed to cause the reaction force to exert from the goalies feet onto the ground around him. The CGI portrayed the reaction force to cause an outward circle of energy in the form of the ground rippling and the wind blowing around the goalie. This is another example of special Action-Reaction Principles in the Shallow Soccer Animation when it comes to strong characters..
