A estimated answer would be 15 an exact answer would probably be maybe 15 1/4 I think.

Write the standard equation for the circle center (-6,8) that passes through (0,0)

Reil [10]

Answer:

D

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (- 6, - 8), thus

(x + 6)² + (y + 8)² = r²

The radius is the distance from the centre to a point on the circle

Calculate r using the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 6, - 8) and (x₂, y₂ ) = (0, 0)

r = $\sqrt{(0+6)^2+(0+8)^2}$ = $\sqrt{36+64}$ = $\sqrt{100}$ = 10

Hence

(x + 6)² + (y + 8)² = 100 → D
