Chapter 11.8, Problem 59E

Work these exercises. (See Example 5.)

Gross National Income of China The gross national income (GNI) of China (in billions of U.S. dollars) can be approximated by

$f\left(t\right)=1000e^{.165t}$

where $t=0$ corresponds to the year 2000. (Data from: www.worldbank.org.)

Find $f^{\prime }\left(t\right)$

At what rate was the GNI changing in 2000? Round to the

nearest integer.

Repeat part (b) for 2016.
