Given a right triangle, suppose "c" is the longest side called the hypotenuse, and "a" and "b" are the other sides called the legs. If a = 3 and b =4, find c.
Pythagorean theorem: a^2 + b^2 = c^2 3^2 + 4^2 = c^2 9 + 16 = c^2 25 = c^2 sqrt(25) = sqrt(c^2) Answer: c = 5
You're just been assigned your first chemistry test 1 week from today. The instructor provides you with suggested practice problems to complete prior to each class period along with the expected readings that will be covered during each lecture. Suggest 5 ways you can have the best chance at success in order to ace your first test.
1. Review reading assignments prior to lecture, and identify puzzling concepts to clarify during the actual lecture. 2. After each lecture period, reflect on what you've learned. Know the purpose of each assignment, what to do and how to do it. Then review the areas you are having problems with. Target those areas. 3. Break up your study time into small, fragmented pieces throughout the week. DON'T delay all of your studying to the night before the test! 4. Practice Practice Practice those chemistry problems repetitively each day. Repetition and experience are key to understanding and remembering material more effectively. 5. Get a good night's rest (at least 6-8 hours) the night before the test and have a sufficient breakfast in order to function at optimum levels during the exam.
If ln(3x-2) =1, then x = ?
ln(3x-2) = 1 e^ln(3x-2) = e^1 3x-2 = e 3x = e +2 x = (e+2)/3
