Question

A flying disk is thrown into the air from a height of 25 feet at a time T=0. The function that models this situation is h(t) = 16t 2 squared + 75 t + 25, where T is measured in seconds and H is height in feet. What values of T best describe the times when the disc is flying in the air?

Answer 1

Answer 2

Incorrect question, the correct Question is h(t) = -16t 2 squared + 75 t + 25

Answer:

Therefore,

t = 5 seconds suits the best value.Step-by-step explanation:

Given:

The function that models flying disk situation is

$h(t)=-16t^{2}+75t=25$

Where  is measured in seconds and h is height in feet.

To Find:

What values of T best describe the times when the disc is flying in the air?

t = ? at h(t) = 0

Solution:

The function that models flying disk situation is

$h(t)=-16t^{2}+75t+25$

Put h(t) = 0

$0=-16t^{2}+75t+25$

$(t-5)(t+\dfrac{5}{16})=0\\\\t = 5\ or\ t =-\dfrac{5}{16}$

As t cannot be negative

t = 5 s

Therefore,

t = 5 seconds suits the best value.
