In 2000, the population of a country was approximately 6.34 million and by 2040 it is projected to grow to 9 million. Use the exponential growth model A = A0 e^kt, in which t is the number of years after 2000 and A0 is in millions, to find an exponential growth function that models the data.
By which year will the population be 7 million?
a. The exponential growth function that models the data is A = [ ].
(Simplify your answer. Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.)
b. The country's population will be 7 million in the year [ ].
(Use the answer from part a to find this answer. Round to the nearest year as needed.)
