An unmanned reconnaissance drone is flying over enemy territory using a preprogrammed flight pattern for a total flight time of 28 minutes. Its height (in feet) can be modeled by the function H(t)=−1/2t^2+17t+683, where t is the number of minutes of flight time since takeoff. Due to the terrain, the enemy's radar cannot track the drone when it is below 827 feet. For what values of t will the drone be exactly 827 feet high? A) Earliest time= ___ minutes B) Latest time=____ minutes
