The center and radius of circumferenceMare (0,0) and10, respectively. The center and radius of circumferencePare (8,0) and2, respectively. Circumference Q is internally tangent to circumferenceMand externally tangent to circumferenceP.Of course that there are infinitely many circumferences Q which have this property. Determine and graph the equation of the curve that contains the centers of all the circumferences of theQkind.
