EastWind [94]

Answer:

11 seconds

Step-by-step explanation:

If the height h(t) of the sunglasses after t seconds is given by the polynomial function

h(t)=-16t²+1936

The sunglasses will hit the ground when the height h(t)=0

h(t)=-16t²+1936=0

-16t²+1936=0

-16t²=-1936

t²=1936/16=121

t=√121=11 seconds

The Sunglasses will hit the ground 11 seconds after it is dropped by the pilot.

morpeh [17]

Answer:
