Problems 9 and10 refer to the following situation. Cole is standing on a level playing field when he throws a ball to Janice. The height H of the ball in feet above the ground s seconds after Cole throws it is given by the function H = f(s) = 5.5 - 2(s - 1)2 9. The maximum height of the ball above the ground will be (a) H = 2 feet (b) H = 5.5 feet (c) H = 3.5 feet (d) H = 7.5 feet (e) H = 10 feet 10. Janice does not catch the ball. How many seconds will pass before the ball hits the ground? (a) t = 1 seconds (b) t = 2.5 seconds (c) t = 2.66 seconds (d) t = 3 seconds (e) t = 1.87 seconds 11. Suppose that A is the degree measure for an angle. Which of the following expressions must be equal to sin (A + 720%)? (a) sin(-A) (b) - cos(A) (c) - sin (A) (d) cos( A) (e) sin(A) 2 12. Suppose that b is the radian or degree measure of an angle. As along as all factors are defined, which of the following expressions is equal to cot (b) cos(b) csc(b) (a) cos=(b) (b) 1 (c) sin?(b) (d) tan(b) (e) S cos" (b ) sin (b)
