Inverse Variation

Inverse Variation In an inverse variation the change in two variables is such that with an increase in the first variable the second variable decreases. But if the first variable decreases then an increase in the second variable is recorded. The relation of the speed of a vehicle and the time taken by the vehicle to cover a certain distance is an example of inverse variation. Inverse variation can be represented as xy = k Where x and y are variables and k is a constant of proportionality. Example 1: If a biker drives at 50 miles per hour and takes 1.5 hours to cover a certain distance, what will be the constant of proportionality? Solution: The two variables we have are the speed of the bike s and time taken to cover the distance t. Variable s and t have inverse variation with respect to each other. Thus the inverse variation is st = k Putting the values, 50 x 1.5 = k k = 75 Thus the constant of proportionality is 75. Example 2: The time taken by an ice cube of one square inch to melt at 78 degrees is 3 hours. Find the constant of proportionality. Solution: We have two variables here. The first variable is the time taken (h) to melt. The second variable is the temperature (t) at which the ice cube is melting. Thus, ht = k Putting the values of the variables we get, 3 x 78 = k k = 234 Thus the constant of proportionality is 234.

Online Self Paced Tutors

Online Self Paced Tutors Self-paced in math is the courses which offer the same material and coursework as in lecture regular classes. But the self-paced study is mostly considered as independent study in math where the student learns according to ones own pace. The test can be scheduled at the centers according to the requirements. Self-paced study requires lot of dedication and hard work as the student is responsible to learn the course material. Learning can include teaching, online tutoring, lectures, books and other available services. Many educational institutions support self-paced education. Mostly the topics offered for self-paced study are, basic math, algebra, trigonometry, geometry and many more. Example 1: Find the solution for 6 [ 3 + (9 - 11) ]? Solution: Given is 6 [ 3 + (9 - 11) ] integers with different mathematical operations. Start with the inner bracket (9 -11) = -2 This gives 6 [3 + ( 2)]. Now 3 [ 3 2 ] = 3 [ 1 ]. Multiplying the integers with same signs gives 3 * 1 = 3. Hence the solution to the question is 3. Example 2: Solve for the variable x in the equation 7 x 4 = 10? Solution: First step: Adding 4 on both sides of the given equation. (7 x 4) + 4 = 10 + 4. This gives 7 x = 14. Now dividing both sided of the equation by 7. This gives 7 x/ 7 = 14 / 7. This reduces the given equation to x = 2. Hence the solution is x = 2.

Advanced Placement Or International Baccalaureate

Advanced Placement Or International Baccalaureate High school students mostly juniors and seniors annually take AP (Advance Placement Tests) or IB (International Baccalaureate tests), but which is better? Jay Mathews from The Washington Post argues in an article that the IB tests are slightly better because they force students to write more. Therefore, students must think deeper and provide more-detailed answers. He believes that this is the type of thinking that students will be exposed to in college. The AP exams are mostly multiple choice questions that students traditionally find easier and less thought-provoking. However, there is minimal guessing for the IB. Also, the IB has a 4,000 word essay that the AP exam does not have. Both tests and programs are great for high school students. They are engineered to accurately depict college courses. The tests are about 3-5 hours long and are widespread in most high schools. However, the AP exams are much more common than the IB tests. Also, it is easier for high school students to earn college credit through the AP exams because most college administrators are more familiar with AP exams. Students still must pass the test to receive credit. However, Mathews argues that the IB is beginning to receive more recognition. He states that college administrators are now paying more attention to the IB, and more colleges are offering credit for it. Most high schools offer one test or the other, and the test is typically the AP. Not many high schools offer both exams, but Mathews insinuated that high schools might begin to catch on to the IB and offer both. The AP/IB debate remains a mild debate and neither side is strongly pushing for one test over the other. If anything, high schools are pushing for grants to offer both programs and let students decide which program to pursue. Both programs, however, are strongly correlated to students success in college. Studies show that students who enroll in AP/IB programs are more likely to graduate from college within four years. Studies also indicate higher college grades and more success after college. Students should consider enrolling in these programs because both allow students to take college level classes. Students can then have an accurate idea of how much more demanding and rigorous college is compared to high school.

Online Surface Area of a Cylinder Tutors

Online Surface Area of a Cylinder Tutors A cylinder is a 3-dimensional geometric figure which has congruent circular bases on its top and its bottom. These bases are joined by the curved surface of the cylinder which is elongated to a certain height. The total surface area is the sum of all the surface areas of a given geometric shape. This implies that the total surface area of a cylinder is calculated by adding the areas of the bases of the cylinder and the curved surface area of the cylinder. Example 1: What is the total surface area of a cylinder whose radius of the circular base is 4m and the height of the cylinder is 6m? Given: radius, r = 4m Height of the cylinder, h= 6m Total Surface area of cylinder, SA = (2* * r2) + (2* * r* h) This gives: Total surface area of the cylinder, SA= (2* * 42) + (2* * 4* 6) = 32+ 48 = 251.3m2 Therefore, the total surface area of the given cylinder is 251.3m2 Example 2: What is the total surface area of a cylinder whose radius of the circular base is 7m and the height of the cylinder is 10m? Given: radius, r = 7m Height of the cylinder, h = 10m Total Surface area of cylinder, SA = (2* * r2) + (2* * r* h) This gives: Total surface area of the cylinder, SA= (2* * 72) + (2* * 7* 10) = 98+ 140 = 747.7m2 Therefore, the total surface area of the given cylinder is 747.7m2

Online Surface Area of a Square Pyramid Tutors

Online Surface Area of a Square Pyramid Tutors A square pyramid is a 3-dimensional geometric figure consisting of a base and 4 triangles. These 4 triangles of the pyramid join the base to a single point on top known as the apex or the vertex of the pyramid. A pyramid can have different bases, but the pyramid having a square base is known as the square pyramid. Surface area of a square pyramid can be calculated by finding the sum of the area of the base and the areas of the 4 triangles together. Example 1: What is the surface area of a square pyramid which has a base length of 5m and a slant height of 12m? Given: base length, b= 5m Slant height of the pyramid, s = 12m Since it is a square pyramid, the base of the pyramid is a square. Surface area of a square pyramid = b2 + 2* b* s This gives: Surface area of the square pyramid, SA= (5)2 + (2 * 5 * 12) = 25+ 120= 145m2 Therefore, the surface area of the given square pyramid is 145m2 Example 2: What is the surface area of a square pyramid which has a base length of 7m and a slant height of 11m? Given: base length, b= 7m Slant height of the pyramid, s = 11m Since it is a square pyramid, the base of the pyramid is a square. Surface area of a square pyramid = b2 + 2* b* s This gives: Surface area of the square pyramid, SA= (7)2 + (2 * 7 * 11) = 49+ 154= 203m2 Therefore, the surface area of the given square pyramid is 203m2

What is it Like to Attend Ithaca College

What is it Like to Attend Ithaca College The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences, as well. Ene graduated from Ithaca College in 2014 with a Bachelors degree in Biochemistry. She tutors Biology tutoring, Chemistry tutoring, Physics tutoring, and many other subjects. Check out her review of Ithaca College: VT: Describe the campus setting and transportation options.How urban or safe is the campus?Are there buses or do you need a car/bike? Ene: The Ithaca College campus is safe, a bit secluded, and of medium size. On-campus housing is very close to campus classes, and in the summertime, I would advise students to walk, instead of drive, to their classes. The winters are very cold, however. The college is about 20-25 minutes from the Ithaca Commons by foot. Buses arrive every thirty minutes on the weekdays, and they run until a little after 1:00 a.m. The campus is secluded from the town, and it is kept safe by public safety officers who drive around, especially at night. Only residents of a building have access to the main entrance with their IDs. In the event that a student is afraid to walk alone, there are escort services available free of charge. A car or bike is not necessary, especially if you live on campus, but a car can be useful after the buses stop running (if you live off campus and during the winter). VT: How available are the professors, academic advisers, and teaching assistants? Ene: The professors and advisers are very easy to reach, especially during office hours. But most times, I could just stop by a professors office and have a chat with him or her. Most teaching assistants (TAs) are students, and they provide their email information to students. They are available through TA sessions and by appointment. VT: How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Ene: There are numerous socialization opportunities, especially for freshmen. The First Year Experience introduces students to various student organizations and provides a list of fun things to do in Ithaca. The resident assistants are also very supportive, and they always come up with activities that students can do together. Collaborations between student organizations provide another way for students who are not freshmen to socialize. VT: Which majors/programs are best represented and supported?What did you study and why? Did the university do a good job supporting your particular area of study? Ene: Ithaca College is known for its Music, Theatre, and Television Radio majors. I studied Biochemistry because I love both biology and chemistry, and I wanted a chance to study both. The department is small when compared to other departments, and this made it easier to get to know my fellow students and teachers in the department. Professors had time to answer my individual questions, and I was able to do research with a professor who supervised and advised me. VT: How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Ene: I was an international student who enrolled in the spring semester, and the friends I made were mostly exchange students who left in following semesters. It was a bit rough for me to go out and meet people, but once I started to join clubs and take classes outside my major, I had more chances to socialize. Ithaca College has no Greek life of its own, but students can join fraternities and sororities at Cornell University. VT: How helpful is the Career Centerand other student support services?Do many reputable companies recruit on campus? Ene: Career Services offers walk-in sessions for tasks like resume and cover letter writing. They also provide opportunities for students to complete mock interviews. Every semester, there is at least one job fair with between 80-100 recruiters. In addition, there is an alumni mentorship program that allows students to contact and seek advice from alumni of the college. VT: How are the various study areas such aslibraries, the student union, and dorm lounges? Are they over-crowded, easily available, spacious? Ene: Dorm lounges are hardly ever used unless there is a floor event or when students want to watch shows together. There is only one library, which can get crowded during exam periods. But there are multiple computer labs and study lounges where students can study. The library is open 24 hours a day on weekdays. The computer labs are open until late at night. VT: Describe the surrounding town. What kinds of outside establishments / things to do are there that make it fun, boring, or somewhere in between?To what extent do students go to the downtown area of the city versus staying near campus? Ene:Ithaca also houses Cornell University, and students from Ithaca College have the chance to join clubs at Cornell University and to take classes there. It is a great way to meet other students. Ithaca has many gorges and parks that are fun to explore in the summer, and there are many restaurants downtown to explore, as well. VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Ene: The largest classes are typically introductory classes of up to 100 students (in the sciences). But once you move from 100-level classes, class sizes usually fall to between 10 (for small classes) to about 40 (for the larger classes). I was pleased with the class size because there was more room for individual questions and discussions. VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Ene: I went into college as a Biology major. At that point, I hated chemistry. I remember my first chemistry class with a certain professor and immediately falling in love with chemistry because he taught it so well and enthusiastically. So after that class, I changed my major to Biochemistry. Check out Enes tutoring profile. The views expressed in this article do not necessarily represent the views of Varsity Tutors.

Taking a Summer Break from Anxiety for Teens with ADHD

Taking a Summer Break from Anxiety for Teens with ADHD Summertime typically provides a much-needed break from the academic and social pressures of school for kids with ADHD. Elementary school kids can spend their summers involved in activities that play to their strengths and minimize their weaknesses. They have an opportunity to focus on making new summer friends, forming friendships that arent complicated by school anxiety and stress. In an ideal world, teenagers with ADHD also have the chance to take a real summer break from high school pressures. However, as competition for college admissions and career success grows, many high school students are increasingly encouraged to maximize their summer breaks by participating in experiences that will bolster their chances of getting into their preferred college. This often means seeking out competitive internships and participating in multiple sports or intense extracurricular activities, sometimes while also holding down a part-time job. Taking a break from the social pressure of high scho ol is also more challenging with social media playing such a prominent role in teenage social life. Teens continue to feel the pressure to keep up with their classmates, often comparing themselves to their peers and scanning Instagram posts to make sure theyre not missing out on (or being left out of) events and activities. This year-round pressure is just one of many factors that researchers and clinicians think may be driving the rise in anxiety among teenagers. A recently published article in the Journal of Developmental Pediatrics found that in the U.S. rates of anxiety disorder diagnoses increased 20% between 2007-2012.1 Many clinicians suspect that rates have increased even more rapidly between 2012 and 2018. In fact, according to the National Institute of Mental Health, about one-third of todays adolescents will experience an anxiety disorder during their lifetime. Teens with ADHD are at even higher risk, with up to 50% experiencing significant anxiety. While some of the factors driving up teen anxiety are pervasive and cant be changed in a single summer, there are still many things parents can do to help their teens keep anxiety in check. Help your teen focus on experiences that are meaningful and personalized. Its smart to start thinking about college and career paths early on, and to use time away from school to build skills and experiences that bolster college and career success. But for teens with ADHD who have struggled to succeed in school, and whose self-confidence has eroded over time, focusing first and foremost on finding activities and internships that build confidence and self-esteem is important. Encourage your teen to think about the big picture and seek out experiences that tap into his or her strengths and minimize weaknesses. Ideally these experiences should be in areas that your teen is passionate about, where he or she can feel confident in his or her knowledge and abilities and be an equal or a leader among his or her peers. Encourage your teen to devote some time working on academic skills. A complete break from academics during the summer months can make it difficult for teens with ADHD to start the new school year off with confidence. So, while your teens activities and internships should play to his or her strengths, that doesnt mean your teen shouldnt spend any time building up weaker academic skills. The trick is to set your teen up for success by providing him or her with academic experiences that build confidence as well as skills. Working with learning professionals who provide personalized instruction tailored to your teens learning style and strengths is the most surefire path to academic confidence and success. Quality family time is important. Its normal and healthy for teens to prefer to spend time with friends rather than family. But, that doesnt mean that family time isnt important. In fact, family time can provide a healthy break from social pressure, and the anxiety that comes with it for many teens with ADHD. Schedule family activities that include a break from technology when teens (and their parents) dont check their social media accounts for extended stretches of time. The focus of this time should be on blocking outside distractions and spending quality time with each other. Activities that are naturally less compatible with cell phone use (like hiking, swimming, amusement parks, paintball, horseback riding, trampoline parks) will help make the technology breaks a little easier. Work with a therapist if your teen seems highly anxious or unmotivated. Finding time for therapy appointments can be hard during the school year. If you are worried about your teens level of anxiety, or if he or she seems to be constantly irritable or unmotivated, use the summer months to find a therapist who can meet with you and your teen to assess his or her mood and anxiety. Even a few appointments with a good therapist can make a big difference when it comes to treating anxiety and having a go-to therapist your teen can meet with if anxiety spikes in the fall can mean getting treatment more quickly when your teen needs it the most.
