7-47.

Integrate.

1. $\int 10 ^ { \pi - 1 } d x$

What does the graph of $y = 10^{π − 1}$ look like? What will its area function look like?

1. $\int ( 9 ^ { t - 1 } ) d t$

$\text{Recall that }9^{t-1}=(9^{t})(9^{-1})=\frac{9^{t}}{9}.$

1. $\int \cos(4m − 3)dm$

$= k\sin(4m − 3) + C$
Find the value of the constant $k$.
