Dan uses a remote control to make his drone take off from the ground. function h represents the height, in feet, of the drone t seconds after it begins flying. h(t)= -16(t-2)^2+64 which statement correctly describes this situation? a. the drone is on the ground at 0 and 2 seconds. b. the drone is on the ground at 0 and 16 seconds. c. the drone is on the ground at 0 and 4 seconds. d. the drone is on the ground at 2 and 4 seconds.

The drone is on the ground at 0 and 4 seconds.

Step-by-step explanation:

PLATO test

C.   The drone is on the ground at 0 and 4 seconds.

Step-by-step explanation:

Here the function that shows the height of the drone,

Where t is the time in seconds.

Since, the drone is ground when, h(t) = 0

  (by subtracting 64 from both sides 64)

          (dividing both sides by -16 )

            (by subtracting 4 from both sides)

⇒ t = 0 or t = 4  

Thus, Option C is correct.
