Question 1158515: The population of a particular city was 22 million in 1984; in 1994, it was 31 million. The exponential growth function A=22e^kt describes the population of this country t years after 1984. Use the fact that 10 years after 1984 the population increased by 9 million to find k to three decimal places.
