Answer:

5.12 seconds to the nearest hundredth.

Step-by-step explanation:

When the ball hits the ground h = 0 so

-16t^2 + 81t + 5 = 0

t =  [ -81 +/- sqrt ((81^2 - 4 * -16 * 5)]/ (2*-16)

=  (-81 +/- sqrt 6881) / -32

= 5.12 , -0.6

So the answer is 5.123 seconds.

A cylinder has volume 45 pie and radius 3. What is its height?
liraira [26]

Answer:

5 units

Step-by-step explanation:

The <u>volume of the cylinder</u> is the area of the circle multiplied by it's height. Therefore, the volume of the cylinder is πr² × h, which when simplified, gives us πr²h. Let's substitute the volume and the radius in the formula to find the height.

⇒ πr²h = Volume of cylinder

⇒ (π)(3²)(h) = 45π

Now, simplify the equation to evaluate the area of the cylinder.

⇒ (π)(3²)(h)/(3²)(π) = 45π/(3²)(π)

⇒ (h) = 45π/(9)(π) = 45/(9) = 5 units
