A bouncy ball is dropped such that the height of its first bounce is 5.5 feet and each successive bounce is 64% of the previous
ahrayia [7]

Answer:

  0.4 ft

Step-by-step explanation:

It can be convenient to let a spreadsheet compute the values for you. Here, we have written an explicit formula for the height of the n-th bounce:

  h = 5.5×0.64^(n-1)

We have written the formula this way because we are given the height of the first bounce, not the starting height. Each bounce multiplies the height by a factor of 0.64. Then the 7th bounce will have a height of ...

  h = 5.5×0.64^6 ≈ 0.378 ≈ 0.4 . . . . feet

The surface area of a cube is 6(a/4)^2, where a is a positive constant. What is the perimeter of one face of the cube?
maksim [4K]

Answer: The perimeter is a

Step-by-step explanation:

1. By definition, the formula for calculate the surface area of a cube is:

SA=6s^{2}

Where s is the lenght of any edge of the cube.

2. You know that the surface area of the cube of the problem is 6(a/4)^{2}, therefore the lenght of each edge of the cube is:

s=a/4

3. Each face of the cube is a square, therefore the perimeter of one face is:

P=4s

P=4(a/4)

P=4a/4

P=a
