Start with the equation of a circle whose center is at (h,k) and whose radius is r:
(x-h)^2 + (y-k)^2 = r^2
Substituting the given coordinates of the center:
(x-5)^2 + (y-[-5])^2 = r^2, or (x-5)^2 + (y+5)^2 = r^2
Substituding the given coordinates of a point (6,-2) on the circle:
(6-5)^2 + (-2+5)^2 = r^2
Simplifying:
1^2 + 3^2 = r^2, or 1 + 9 = r^2, or 10= r^2. Then r = sqrt(10).

Answer:
- Earth is 85.71 times heavier than moon
- Jupiter is 333.33 times heavier than Earth
Step-by-step explanation:
Given
- The mass of Earth is about 6 x 10^24 kilograms = e
- The mass of the moon is about 7 x 10^ 22 kilograms = m
- The mass of Jupiter is about 2 x 10^27 kilograms = j
<u>The difference in mass</u>
- e/m = 6 x 10^24 / 7 x 10^ 22 = 600/7 = 85.71
Earth is 85.71 times heavier than moon
- j/e = 2 x 10^27 / 6 x 10^24 = 2000/6 = 333.33
Jupiter is 333.33 times heavier than Earth
