What do we use to find a? And what do we use to find b? Also what do we use to find the values of a and b?

a. Find a formula for P(t), the population after t days, with base e. b. Simplify your answer to part a to eliminate log, In, bases e or 10. C. After how many days were the number of cases 100? (doubling time) d. After how many days will the number of cases be 600? e. Extra Point: Do part d without solving another equation, P (t) = Ackt What do we use to find A ? "P is fifty when t is zero." O "t is fifty when P is eight." "t is fifty when P is zero." "P(t) is 0 when t is 0." O none of these "P is 8 when t is 150." O "P is fifty when t is eight."
