Distance to Earth From an exterior point P that is h units from a circle of radius r, a tangent line is drawn to the circle (see the figure). Let y denote the distance from the point P to the point of tangency T.(a) Express y as a function of h. (Hint: If C is the center of the circle, then PT is perpendicular to CT.)(b) If r is the radius of Earth and h is the altitude of a space shuttle, then y is the maximum distance to Earth that an astronaut can see from the shuttle. In particular, if mi and mi, approximate
