In​ 2012, the population of a city was 6.38million. The exponential growth rate was 2.38​% per year.
Aleksandr-060686 [28]

The exponential growth function is P(t) = 6.38 million x (1.0238^t).

The population of the city in 2018 is 7.35 million.

The year the population would be 9 million is 14.46 years.

The doubling time is 29.12 years.

<h3>What is the exponential growth function?</h3>

FV = P (1 + r)^n

  • FV = Future population
  • P = Present population
  • R = rate of growth
  • N = number of years

6.38 million x (1.0238^t)

Population in 2018 = 6.38 million x (1.0238^6) = 7.35 million

Number of years when population would be 9 million : (In FV / PV) / r

(In 9 / 6.38) / 0.0238 = 14.46 years

Doubling time = In 2 / 0.0238 = 29.12 years
