What is the standard form that has a center (1,3) and a radius of 9

klasskru [66]

$\huge\boxed{(x-1)^2+(y-3)^2=9^2}$

Start with the standard form of a circle, where $(h,k)$ is the center of the circle and $r$ is the radius.

$(x-h)^2+(y-k)^2=r^2$

Plug in the known values.

$\boxed{(x-1)^2+(y-3)^2=9^2}$

This is the circle's equation in standard form.

In ΔFGH, the measure of ∠H=90°, the measure of ∠G=75°, and FG = 24 feet. Find the length of HF to the nearest tenth of a foot.

chubhunter [2.5K]

Answer:

HF ≈ 23.2 ft

Step-by-step explanation:

Using the sine ratio in the right triangle.

sin75° = $\frac{opposite}{hypotenuse}$ = $\frac{HF}{FG}$ = $\frac{HF}{24}$

Multiply both sides by 24

24 × sin75° = HF , thus

HF ≈ 23.2 ft ( to the nearest tenth )
