Rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the

Brut [27]

Answer:

The time that the rocket will hit the ground is 12.87 seconds.

Step-by-step explanation:

Given : The rocket is launched from a tower $y=-16x^2+199x+90$ . The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation.

To find : The time that the rocket will hit the ground ?

Solution :

When the rocket hit the ground i.e. height became zero y=0,

Equation is $y=-16x^2+199x+90$

Substitute y=0,

$-16x^2+199x+90=0$

Using quadratic formula, $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-(199)\pm\sqrt{(199)^2-4(-16)(90)}}{2(-16)}$

$x=\frac{-199\pm\sqrt{45361}}{-32}$

$x=\frac{-199+\sqrt{45361}}{-32},\frac{-199-\sqrt{45361}}{-32}$

$x=-0.43,12.87$

Reject negative value.

The time taken is 12.87 seconds.

The volume of the styrofoam collar is approximately 1,960.35 $in^{3} .$

Step-by-step explanation:

Step 1:

The given styrofoam collar is a hollow cylinder. A hollow cylinder consists of an outer radius and an inner radius.

This given hollow cylinder has an outer radius of 8 inches and an inner radius of 5 inches. The height of the cylinder is 16 inches.

To calculate the volume of a hollow cylinder we subtract the volume of a cylinder constructed with the inner radius from the volume of a cylinder with the outer radius.

Step 2:

The volume of a cylinder, $V = \pi r^{2} h.$
