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

If f(x) = 9(x - 7)^2 – 8<br> Find f( – 4)

____ [38]

Answer:

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:

$P=4s$

$P=4(a/4)$

$P=4a/4$

$P=a$
