The population of a particular country was 29 million in 1980; in 1989, it was 36 million. The exponential growth function A=29e^kt describes the population of this country t years after 1980. Use the fact that 9 years after 1980 the population increased by 7 million to find k to three decimal places.

**Reiny**, Saturday, April 17, 2010 at 9:02pm36 = 29 e^(9k)

1.24138 = e^(9k)

9k = ln (1.24138)

k = ln (1.24138)/9

= ....

take the ln of each side.

ln(36)=ln29+ 9k

k= (ln(36/29)) /9
