Question 1093744: A satellite is in orbit around the moon. A coordinate plane containing the orbit is set up with the center of the moon at the origin, as shown in the following graph, with distances measured in megameters (Mm). The equation of the satellite's orbit is
(The first question is to use a graph to find the closest and furthest the orbit is from the center of the moon. The answers to this are
Closest: 2MM
Furthest: 8MM
There are two points in the orbit with y-coordinates 2. Find the x-coordinates of these points, and determine their distances to the center of the moon. (Round your answers to two decimal places.)
Please help me figure out how to find the x coordinates.
