A) The rancher with 750 ft of fencing wishes to enclose rectangular area and then divide it in 4 pens with fencing parallel to one side of rectangle:
i) Determine the function which models total area of four pens
ii) Determine largest possible total area of four pens
B) The ball is thrown across the playing field. It's path is provided by equation y = -.005x^2 + x +5
C) If ball is thrown directly upward with the velocityof 40 ft/s, its height (in feet) after t seconds is provided by y =40t -16t^2. Find maximum height obtained by the ball?
