Solve.
-The population of a particular country was 23 million in 1981 ; in 1987 , it was 32 million. The exponential growth function $\mathrm { A } = 23 \mathrm { e } ^ { \mathrm { kt } }$ describes the population of this country t years after 1981. Use the fact that 6 years after 1981 the population increased by 9 million to find $\mathrm { k }$ to three decimal places.
