1. Use the multiply-multiply pattern of power functions to find the acceleration at 3 Earth radii from the center. Round to the nearest hundredth.

2. Find the particular equation expressing y as a function of x.

3. What is the acceleration due to Earth's gravity acting on someone standing on the Moon, 63 Earth radii away from Earth's center? Express your answer with 4 places after the decimal.

where Re is the earth's radius,

will answer all you questions.

Note that x/Re is the number of Earth radii from the center.
