Question

Use appropriate formulas from geometry to evaluate the integralWrite the exact answer. Do not round.J0.5

Answer 1

We have the following definite integral

`\int ^9_(0.5)-2dx`

First, we solve the integral.

`\int ^{}_{}-2dx=-2x+C`

secondly, we evaluate it in the limits of the integral.

`\begin{gathered} \lbrack-2(9)\rbrack-\lbrack-2(0.5)\rbrack \\ \lbrack-18\rbrack-\lbrack-1\rbrack \\ -18+1 \\ -17 \end{gathered}`

In conclusion, the answer is -17
