question 164

Multiple Choice

Solve the problem.
-A satellite is to be put into an elliptical orbit around a moon. The moon is a sphere with radius of $149 \mathrm {~km}$ . Determine an equation for the ellipse if the distance of the satellite from the surface of the moon varies from 910 $\mathrm { km }$ to $488 \mathrm {~km}$ .

• A) \(\frac { x ^ { 2 } } { 10592 } + \frac { y ^ { 2 } } { 637 ^ { 2 } } = 1\)
• B) \(\frac { x ^ { 2 } } { 488 } + \frac { y ^ { 2 } } { 910 } = 1\)
• C) \(\frac { x ^ { 2 } } { 637 ^ { 2 } } + \frac { y ^ { 2 } } { 10592 } = 1\)
• D) \(\frac { x ^ { 2 } } { 910 } + \frac { y ^ { 2 } } { 488 } = 1\)
