Question

At what value of x(in megabytes) will A(x)=0? Show all of your work details

Answer 1

204.082 megabytes

EXPLANATION :

From the problem, we have the equation :

`A(x)=\frac{100}{\sqrt[]{x}}-7`

Solve for x when A(x) = 0.

That will be :

`\begin{gathered} 0=\frac{100}{\sqrt[]{x}}-7 \\ 7=\frac{100}{\sqrt[]{x}} \\ \text{Cross multiply :} \\ 7\sqrt[]{x}=100 \\ \sqrt[]{x}=(100)/(7) \\ \text{Square both sides :} \\ x=((100)/(7))^2 \\ x=204.082 \end{gathered}`

The value of x is 204.082
