Acircle has center (5,-4) and radius 8. which gives the equation for the circle?

Use (x - h)^2 + (x - k)^2 = r^2.

Note: (h, k) is the center of the circle.

(h, k) = (5, -4). This means h = 5 and k = -4.

Let r = radius

We now plug and chug.

(x - 5)^2 + (y -(-4))^2 = (8)^2

(x - 5)^2 + (y + 4)^2 = 64

Done.

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
