Answer:

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{8}$ = $\frac{1}{2}$ ( cross- multiply )

2x = 8 ( divide both sides by 2 )

x = 4

Answer:

B. $H(x)=-.008(x-82)^{2}+83$

Step-by-step explanation:

Well lets graph the following equation first,

H(x) = -.011(x - 82)^2 + 75

Then lets graph all the other equations.

Look at the image below↓

So A.

The purple line does not go farther or higher,

so A. is incorrect

The black line goes higher and farther,

meaning it is correct.

The red line goes farther but not higher.

So it is incorrect

Again the blue line does not go farther of higher.

So its wrong.

Thus,

answer choice B. $H(x)=-.008(x-82)^{2}+83$ is correct.

Hope this helps :)
