This week in calculus we took some more ap test. one of the things i am comfortable doin on these test is the growth problems with these problems you use the formula A(not) = e^kt. You know you are using this formula when you see words such as growth over x amount of years, bacteria, decay, birth rate, etc.
33) An investment of 4000 dollars grows at the rate of 320e^0.08t dollars per year after t years. Its value after 10 years is approximately ?
You then plug into your a (not) formula and get your answer. YOu are basically given everything so all you have to plug in is your (t). you then plug in 10 for t and get that it equals $8902. Giving your answer to be B.
ONe thing that i am still having trouble with is taking intergrals of like absolute value and intergrals with substitution.

The trick for integrals with absolute value is that you must find your bounds! You have to split them up.
