Today in class we took a quiz. Many people forgot about adding the constant to the finished problems. This is a chance to redeem yourselves and answer each other's questions. Sort of a redemption quiz. I'll start with a problem, and whomever answers my problem will post another question for the next person to answer.
1. Integral of(x(x+1)^(1/2)dx)

Annuities: Now you can actually solve them!
So now that we actually know how to solve an annuity problem, I figured the time may be ripe to ask another question about them. So......
A) If you were to start off by depositing 10,000 dollars your first year, and every year after that, and it earned 12% interest, how long would it be before you made it to 1 million dollars? What about 1.5 million dollars?
B) Now say you had the same situation, 10,000 dollars every year, but you didn't know the rate at which it was earning interest. What would the rate be if you reached the 1 million dollar plateau after 35 years?
