Question

A countrys population in 1995 was 56 million in 2002 it was 59 million. Estimate the population in 2016. Exponential growth formula

Answer 1

your function will look like this:

population = 56 e^kt, where t = 0 represents 1995
then 2002 ---> t = 7
and 2016 ---> t = 21

for t = 7 (2002)
59 = 56 e^7k
1.05357... = e^7k
7k = ln 1.05357.. = .052185753
k = appr .0074551

pop = 56 e^(.0074551t)
sub in t = 21 and evaluate
