Question

i need help someone explain how to solve this & solve it ( attachment below)

Answer 1

the time issue on this one is in years from 1995; so convert the dates to "years since 1995"

Answer 2

the idea is to solve for the "rate" at which the populations changes.

P = A e^(kt) ; lets algebra this to solve for k, divide out the A

P/A = e^(kt) ; to undo that "e" we have to log it

ln(P/A) = kt ; now divide out the t to solve for k

ln(P/A)
------ = k; we can use this as a formula to determine k
t

Answer 3

A = past/starting amount;
P= present amount
k = rate we are solving for
t = time in years that have passed by
