Chapter 6.2, Problem 15E

B In Problems 15 and 16, explain which of (A), (B), and (C) are equal before evaluating the expressions. Then evaluate each expression to two decimal places.

15. (A)     ${\displaystyle {\int }_0^8{e}^{0.07\left(8-t\right)}}dt$

(B)     ${\displaystyle {\int }_0^8\left(e^{0.56}-e^{0.07t}\right)}dt$

(C)     $e^{0.56}{\displaystyle {\int }_0^8{e}^{-0.07}dt}$
