1.47x= 700

x= 476.19= 477.

Give the equation of the circle whose center is (5 -3) and goes through (2 5)
Alekssandra [29.7K]

Answer:

Step-by-step explanation:

The standard form for the equation of a circle is

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

From the info given, we have the center, (h, k) as (5, -3) and the x and y coordinates of (2, 5).  We will use these to solve for r-squared, then plug back in what we need to write the equation.

(2-5)^2+(5-(-3))^2=r^2 which simplifies to

(-3)^2+(8)^2=r^2 and

9+64=r^2 so

r^2=73

Filling in the equation:

(x-5)^2+(y+3)^2=73
