kakasveta [241]

<em>The word usage in last sentence of the question is not well presented. However, I can understand that you intend to solve for the width of the park</em>

Answer:

$Width = 2\ km$

Step-by-step explanation:

Given

$Length = \frac{3}{8}km$

$Area = \frac{3}{4}km^2$

Required

Determine the Width

For a rectangle:

$Area = Length * Width$

Substitute for Area and Length

$\frac{3}{4} = \frac{3}{8} * Width$

Multiply both sides by $\frac{8}{3}$

$\frac{8}{3} * \frac{3}{4} = \frac{3}{8} * \frac{8}{3}* Width$

$\frac{8}{3} * \frac{3}{4} = Width$

$\frac{24}{12} = Width$

$2 = Width$

$Width = 2\ km$

Given the parent function f(x) = 8x + 9, rewrite the function after the following transformation: reflect over the x-axis. Group

kari74 [83]

Given:

The parent function is

$f(x)=8x+9$

To find:

The function after the reflection over the x-axis.

Solution:

We know that, if a function f(x) reflected over x-axis to get the function g(x), then

$g(x)=-f(x)$

Putting $f(x)=8x+9$ , we get

$g(x)=-(8x+9)$

$g(x)=-8x-9$

The function after the reflection over the x-axis is $g(x)=-8x-9$ .

Therefore, the correct option is B.
