Question

An unmanned reconnaissance drone is flying over enemy territory using a preprogrammed flight pattern for a total flight time of 137 minutes. Its height? (in feet) can be modeled by the function H(t)=1/10t²-23t+1622, where t is the number of minutes of flight time since takeoff.?? ?A.) Due to the? terrain, the? enemy's radar cannot track the drone when it is below 322 feet. For what values of t will the drone be exactly 322 feet? high? Earliest time? = ?? Latest time? = *******Not sure where the question marks came from but the question reads "Due to the terrain, the enemy's radar cannot track the drone when it is below 322 ft. For what values of "t" will the drone be exactly 322 ft? It's asking for the earliest and latest times.*******
