The height, h, in feet of a ball above the ground is given by h = −16t2 + 64t + 80, where t is the time in seconds. How long doe

Gwar [14]

Answer:

t = 5 seconds

Step-by-step explanation:

It is given that, the height h, in feet of a ball above the ground is given by :

$h=-16t^2+64t+80$

Where t is in seconds

We need to find how long does it take the ball to hit the ground? When it hits the ground, its height will be equal to 0. So,

$-16t^2+64t+80=0\\\\t=\dfrac{-64\pm \sqrt{(64)^2-4\times (-16)(80)} }{2\times -16}\\\\t=\dfrac{-64+ \sqrt{(64)^2-4\times (-16)(80)} }{2\times -16},\dfrac{-64-\sqrt{(64)^2-4\times (-16)(80)} }{2\times -16}\\\\t=-1\ s\ \text{and}\ t=5\ s$

Neglecting negative time.

It means ball will take 5 seconds to hit the ground.

The square shown has a perimeter of 32 units. The square is rotated about line k. what is the circumfrence of the base

boyakko [2]

The circumference equal to 25 units

<h3>What is perimeter of square?</h3>

The perimeter of square is 4 times the side.

P= 4* side

The perimeter of the square,

4x = P

Now P is = 32 units then,

32 units = 4(x)

x = 8 inches

So, the diameter of the cylinder formed by the rotation of 8 inches

Now, the circumference of the base is

C = 2πr = πD

If r =8 inches

C = π(8 units) = 8π units

C = 8(3.14) = 25.12 units

Hence, the circumference equal to 25 units
