The figure above shows a Ferris wheel with radius 5 meters as Jalen, whose eye level is at point (0,2), watches his friend, Ashanti, ride in one of the cars as the wheel turns. Let Z denote the distance from Jalen to Ashanti’s car. The diagram indicates the center of the Ferris wheel at the point (12,7) and the position of Ashanti’s car at the point (x, y). If x and y are functions of time t, in seconds, what is the rate of change of Z when x=15, y=11, and dxdt=1 ? (The equation of a circle with radius r and center (h, k) is (x−h)2+(y−k)2=r2.)
