Hi! I really need help!!! A population, P(t) (in millions) in year t, increases exponentially. Suppose P(7)=25 and P(16)=31.

a) Find a formula for the population in the form P(t)=abt. Enter the values you found for a and b in your formula in the blanks below. Round your values to 4 decimal places.
a=
b=

b) If P(t)=aekt, what is the value of k in your formula.
k=
(round to 4 decimal places)
