a. In 2000, the population of a country was approximately 5.92 million and by 2040 it is projected to grow to 9 million. Use the exponential growth Projected model A = Ape, in which t is the number of years after 2000 and A is Population (millions) in millions, to find an exponential growth function that models the data. b. By which year will the population be 10 million? 1950 1970 1990 2010 2030 2050 Year 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 10 million in the year (Round to the nearest year as needed.)
