Answer:

<h2>A) y = 5x</h2>

If C) y = 1/8x then this is also the answer.

Step-by-step explanation:

Proportional relationship:

\dfrac{y}{x}=constant

\dfrac{y}{x}=a\to y=ax

A) y = 5x → a = 5

C) y = 1/8x → a = 1/8

Elanso [62]

9514 1404 393

Answer:

  3 ft

Step-by-step explanation:

The post is 4/24 = 1/6 as tall as the streetlight, so we expect its shadow to be 1/6 as long as that of the streetlight:

  (1/6)(18 ft) = 3 ft

The parking meter post shadow is 3 feet long.

22.
Vlada [557]

Step-by-step explanation:

\sqrt{p}  =  \sqrt[r]{w -  {as}^{2} }

Find raise each side of the expression to the power of r

That's

<h2>( \sqrt{p} )^{r}  =  (\sqrt[r]{w -  {as}^{2} } ) ^{r}</h2>

we have

<h2>( \sqrt{p} )^{r}  =  w -  {as}^{2}</h2>

Send w to the left of the equation

<h2>( \sqrt{p} )^{r}  - w =  -{as}^{2}</h2>

Divide both sides by - a

We have

<h2>{s}^{2}  =  -\frac{( \sqrt{p} )^{r}  - w}{a}</h2>

Find the square root of both sides

We have the final answer as

<h2>s =  \sqrt{ -\frac{( \sqrt{p} )^{r} - w }{a} } </h2>

Hope this helps you
