Question

Evaluate. (Round your answer to two decimal places.)(5pi - 9e) / (7pi + 3e)

Answer 1

-0.29

Step-by-step explanation

We want to evaluate the value of the fraction given to two decimal places.

To do this, we have to know the value of pi and e:

`\begin{gathered} \pi\text{ = 3.1416} \\ e\text{ = 2.7183} \end{gathered}`

Therefore, to simplify the fraction:

`\begin{gathered} \frac{5(3.1416)\text{ - 9(2.7183)}}{7(3.1416)\text{ + 3(2.7183)}} \\ \Rightarrow\text{ }\frac{15.708\text{ - 24.4647}}{21.9912\text{ + 8.1549}} \\ \Rightarrow\text{ }(-8.7567)/(30.1461) \\ =>\text{ -0.2905 }\cong-0.29 \end{gathered}`

That is the answer.
