Answer:

$p(x)=16x-25$

C is the correct option.

Step-by-step explanation:

We have been given that

$r(x)=20x\\c(x)=4x+25$

The profit is the difference of revenue and cost function.

Mathematically, we can write profit function as

$p(x)=(r-c)x$

We know that $(f-g)(x)=f(x)-g(x)$ . Thus, we have

$p(x)=r(x)-c(x)$

Plugging, the r(x) and c(x) functions

$p(x)=20x-(4x+25)$

Distribute negative over the parenthesis

$p(x)=20x-4x-25$

Combine the like terms. 20x-4x = 16x

$p(x)=16x-25$

C is the correct option.

Find the value of each variable. Write your answer in simplest radical form.

Answer:

$y=4\sqrt{3}$

$x=2\sqrt{21}$

Step-by-step explanation:

The diagram is shown in the attachment.

By the altitude -leg rule :

$\frac{14-8}{y}=\frac{y}{8}$

This implies that:

$\frac{6}{y}=\frac{y}{8}$

By cross multiplication:

$y^2=6*8\\\implies y^2=16*3$

Take square root to get:

$y=\sqrt{16*3}$

$y=4\sqrt{3}$

Using the Pythagoras Theorem:

$x^2=6^2+(\sqrt{48})^2$

$x^2=36+48$

$x^2=84$

$x=2\sqrt{21}$
