A ball is thrown directly upward from a height of 6 feet with an initial velocity of 20 ft/sec. The function 5(t) = 16t2 + 201: + 6 gives the height of the ball, in feet, t seconds after it has been thrown. Determine the time at which the ball reaches its maximum height and find the maximum height. 14. A fourth-grade class decides to enclose a rectangular garden, using one side of the school as one side of the rectangle. What is the maximum area that the class can enclose using 32 feet of fencing? What would the dimensions of the garden be in order to yield this area? Page 3 5:5i PM /\\ ' 66F - iO/iS/ZOZi l:l
