1. If a certain cannon is fired from a height of 82 meters above the ground, at a certain angle, the height of the cannonball above the ground, h, in meters, at time. t, in seconds, is found by the function h(t)=−4.9t2+27.5t+8.2. a) Find the maximum height attained by the cannonball. b) Find the time it takes for the cannonball to reach its maximum height. c) Find the time it takes for the cannonball to strike the ground. 2. Determine the quadratic function of the form f(x)=a(x−h)2+k whose graph is given on the right.
