Question

Cindy delivers mail for the local post office. The post office receives mail for everyone that lives within a 5 mile radius. The route covers Anderson and Smith Road that passes through this region.

(A) Let's assume the post office is located at (0,0) point. Write an equation for the circle where the mail is delivered around the region.

(B) Given x^2-y^2-4x-23=0, assuming Anderson follows one branch of the hyperbolic path.

(C) Assuming (-4,-3) is where Cindy starts delivery on Anderson, where does the delivery end?

(D) Cindy finishes her delivery on Anderson at the point where it intersects both the circular boundary and Smith Road. She starts at Smith Road. At the intersection is straight road that cuts through the center of the circular region past the post office. What equation represents Smith Road? Where does Cindy her delivery on Smith Road?
