1. Help with my calculus please! Profit, e, ...

I have to hand in an assignment and am stuck on a few questions. A few people on here helped me before, so I have hope. This stuff is probably a piece of cake to some of you folks. I REALLY APPRECIATE all your help.

1. Find f'(x) and f''(x) if f(x)=5^x

2. Marginal profit is 100-2q. If the profit is $700 when q=10, find the: a: profit function P(q) b: What is the maximum profit? 3. f(t)=(t^2)(e^-2t) Find the absolute max and min values of f(t) on the interval -1<=t<=2 (and equal to) Hint: there are 2 critical values for this function 2.

MHF policy is to not knowingly help with such questions - it's meant to be the work of the student not the work of others. The thread has been closed. pm me if you want to discuss the matter further.
