Question

uppose the population of a country in 1985 was 145 million. In 1995 it was 190 million. Use the formula P = Ae kt to setup an expression to estimate the population of the country in 2005. P = 145e10k P = 145e20k P = 190e10k P = 190e20k

Answer 1

First step is to use the first two populations to find k

Use 1985 population as the "initial" and the 1995 as the final

190 million = 145 million * e ^(k*10) since there's a 10 year gap

once you have k, you can then make a formula that will allow you to calculate the population in 2005 using the 1985 population again as your initial population reference
