Hello,
I hope you and your family are doing well!
(a) The exponential growth model is given by the equation P(t) = P0 * r^t, where P(t) is the population t years after 2010, P0 is the population in 2010 (7420), and r is the annual growth rate (2.3%).
Substituting the given values into the equation gives us:
P(t) = 7420 * 1.023^t
This is the equation that estimates the population t years after 2010.
(b) To estimate the population of the town in 2022, we can substitute t = 12 into the equation:
P(12) = 7420 * 1.023^12
Calculating this gives us:
P(12) = 7420 * 1.023^12 = 7420 * 1.291891 = 9593.45
So the estimated population of the town in 2022 is approximately 9593
Happy to help!
