Answer:

\bigg(\displaystyle\frac{f}{g}\bigg)(5) = 270

Step-by-step explanation:

We are given the following information in the question:

f(x) = 7 +4x\\\\g(x) = \displaystyle\frac{1}{2x}

We have to find the values of \displaystyle\frac{f}{g}(x)

\bigg(\displaystyle\frac{f}{g}\bigg)(x) = \frac{f(x)}{g(x)} = \frac{7 + 4x}{\frac{1}{2x}} = 2x(7+4x)

Putting x = 5, we have:

\bigg(\displaystyle\frac{f}{g}\bigg)(x) = 2x(7+4x)\\\\\bigg(\displaystyle\frac{f}{g}\bigg)(5) = 2(5)(7+20)=270

270 is the required value of \bigg(\displaystyle\frac{f}{g}\bigg)(5).
