Question
Using U.S. Energy Information Administration data for selected years from 2010 and projected to 2040, the U.S. real disposable income per capita (in thousands of dollars) can be modeled by
I(t) = 32.11(1.014)*
where t is the number of years after 2010.
(a) Write the function that models the rate of change of U.S. per capita real disposable income (in thousands of dollars/year). (Round your coefficients to four decimal places.)
I'(t) = 32.10001(1.0140)'-1 ×
(b) Predict the rate of change (in thousands of dollars/year) of U.S. per capita real disposable income in 2038. (Round your answer to four decimal places.)
