A lithotripter is based on an ellipse with the equation given on the right. Find the distance. from the ellipse's center to the kidney stone and to the beam source. Lithotripter: a machine used to crush kidney stones using shock waves. The patient is placed in an elliptical tub with the kidney stone at a focus of the ellipse. A beam is projected from the other focus to the tub, so that it reflects to hit the kidney stone. Use the fact that c = a - b. The distance is (Give an exact answer. Simplify radicals, if possible.) x2 y2 Equation: 1 64 25 10-
