A rectangular billboard 9 feet in height stands in a field so that its bottom is 6 feet above the ground. A nearsighted cow with eye level at 4 feet above the ground stands a| feet from the billboard. Express 0, the vertical angle subtended by the billboard at her eye, in terms of xl. Then find the distance ¤o| the cow must stand from the billboard to maximize 6. 0(x) = O is maximized when #o =
