Question

Tim throws a stick straight up in the air from the ground. The function h = –16t2 + 48t models the height, h, in feet, of the stick above the ground after t seconds. Which inequality can be used to find the interval of time in which the stick reaches a height of more than 8 feet?A.) –16t2 + 48t > 8B.) –16t2 + 48t < 8C.) –16t2 + 48t ³ 8D.) –16t2 + 48t £ 8

Answer 1

Answer:-16t2 + 48t > 8

Step-by-step explanation

Answer 2

The inequality to find the interval of time in which the stick reaches a height of more than 8 feet is $\mathbf{-16t^2 + 48t > 8}$

The height function is given as:

$\mathbf{h(t) = -16t^2 + 48t}$

When the height is more than 8 feet.

More than means greater than.

So, we have:

$\mathbf{h(t) >8}$

Substitute $\mathbf{h(t) = -16t^2 + 48t}$ in $\mathbf{h(t) >8}$

$\mathbf{-16t^2 + 48t > 8}$

Hence, the required inequality is $\mathbf{-16t^2 + 48t > 8}$
