The revenue function is,

R(x)=700x-0.5x^2

For maximum and minimum value, the first derivative of function is equal to 0.

Determine the first derivative of revenue function.

\begin{gathered} \frac{d}{dx}R(x)=\frac{d}{dx}(700x-0.5x^2) \\ R^{\prime}(x)=700-0.5\cdot2x \\ =700-x \end{gathered}

For maximum and minimum value, R'(x) = 0. So

\begin{gathered} 0=700-x \\ 700=x \end{gathered}

Since x = 700 corresponds to maximum or minimum value of revenue.

Determine the second derivative of revenue function.

\begin{gathered} \frac{d}{dx}R^{\prime}(x)=\frac{d}{dx}(700-x) \\ R^{\doubleprime}(x)=-1 \end{gathered}

Since second derivative of revenue function is less than 0 for every value of x. So x = 700 corresponds to maximum value of revenue.

So 700 villas rented to produce maximum revenue.

Answer: 700 villas

<u>The factored form, use variables/numbers outside the square:</u>

  • (x + 6)(x - 4)

<u>The standard form, use variables/numbers inside the square:</u>

  • x² + 6x - 4x - 24 = x² + 2x - 24

sashaice [31]

Answer:

9

Step-by-step explanation:

We can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 1 -10)/(-1 -0)

   = -9/-1

   = 9
