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 )
