Solve.The outline of a certain planet can be considered a circle with a radius of approximately 4000 miles. Thus, if the center of this planet is located at (0, 0), then an equation for this circle is 
. Suppose an incoming meteor is approaching the planet in a hyperbolic path. The equation describing the meteor's path is 
Will the meteor strike the planet? If so, locate the point (x, y) where the meteor will strike. Assume that x and y are both positive, and round to three significant digits.
A. Yes, at the point (x, y) ? (2000, 3460).
B. Yes, at the point (x, y) ? (4160, 4000).
C. No, the meteor will not strike the planet.
D. Yes, at the point (x, y) ? (3220, 4000).
