Question

The population (in millions) of a country in 2007 and the expected continuous annual rate of change k of the population are given. †
Country 2007 Population k
Latvia 2.3 − 0.006


(a) Find the exponential growth model P = Cekt for the population by letting t = 0 correspond to 2000.


(b) Use the model to predict the population of the country in 2011. (Round your answer to two decimal places.)
million

Answer 1

P = Ce^kt = Ce^(-0.006)

p(7) = 2.3 =Ce^-0.006(7)
C = 2.40?

for t = 11

P = 2.40e^(-0.006(11)) = 2.25 million?

Answer 2

cool works.
