a ball is thrown straight up from the top of a 128 foot tall building with an initial speed of 32 feet per second. the height of
STatiana [176]
Factoring, you have
  h(t) = -16(t^2 -2 -8) = -16(t -4)(t +2)

The ball hits the ground when h(t) = 0, so
  0 = -16(t -4)(t +2)
  t = 4 or -2

The positive solution is the one of interest.
  It will take 4 seconds for the ball to hit the ground.

A cube has a side length of x inches. What expression represents the total volume, in cubic inches, of the cube?
Pie

Answer:

Volume = x^3 cubic inches

Step-by-step explanation:

A cube is the 3D version of a square. Since one side length is x inches, all the other side lengths are same, x inches each.

We know,

Volume = area of base * height

THe base is a square and the area is side * side. We know each side is x, so we have:

Area of Square = Area of Base = x * x = x^2

Now, we know height is also same side length, x, thus the volume becomes:

Volume = area of base * height

Volume = x^2*x

We add the exponents when we have same base multiplied, so the expression for volume becomes:

Volume = x^2*x=x^3
