Question

In 2012 the population of a city was 6.25 million the exponential growth rate was 3.22% per year

find the exponential growth function estimate the population of the city in 2018

Answer 1

ok, expnential growth


`F=A(1+r)^t`
F=final amount
A=initial amount
r=growth rate iin decimal form
t=time in years elapsed


so given
A=6.25 million
r=3.22%=0.0322
t=2018-2012=6

so

`F=6.26(1+0.0322)^6`

`F=7.57`

so it will be about 7.57 million in 2018
