A function of the form P t = a b t represents the population (in millions) of the given country t years after January 1, 2000. a. Write an equivalent function using base e; that is, write a function of the form P t = P 0 e k t . Also, determine the population of each country for the year 2000. b. The population of the two given countries is very close for the year 2000, but their growth rates are different. Use the model to approximate the year during which the population of each country would reach 10.5 million. c. Haiti had fewer people in the year 2000 than Sweden. Why would Haiti reach a population of 10.5 million sooner?
