While hovering near the top of Ribbon Falls in Yosemite National park at 1600 feet, a helicopter pilot accidentally drops his sunglasses. The height h(t) of the sunglasses after t second is given by the polynomial function h(t)=-16t^2+1600. When will the sunglasses hit the ground? (Hint: Let the height, h(t), be 0 and solve for t.)

10 seconds

Step-by-step explanation:

Plug in 0 as h(t) and solve for t:

h(t) = -16t² + 1600

0 = -16t² + 1600

-1600 = -16t²

100 = t²

10 = t

So, the sunglasses will hit the ground after 10 seconds

your answer is a

step-by-step explanation:

4*4*4*4=256

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
