Transcribed Image Text:

A small flying toy drone is launched into the air, rises for a time, and then crashes to the ground. The drone's height above the ground, in metres, can be modelled by the function: h(t) = e(20 4t) where t is in seconds. a) How fast is the drone rising when it is launched? (to one decimal place, no units) A/ b) At what time does the drone reach its maximum height? (no units) N c) At what time does the drone crash?
