A tennis ball is dropped from an initial height of 30 feet. It bounces 5 times, with each bounce height being about 2/3 of the height of the previous bounce.

Step-by-step explanation:

I'm thinking you want to know the height of the ball on that 5th bounce, right? This is of the form

where a is the initial height and b is the decay factor.  If the ball comes up to 2/3 of its height from the previous bounce, then b = 2/3 and our equation is

If you want to know the height y of the 5th bounce x, sub in a 5 for x and solve for y:

and get that

y = 320/81 or as a decimal, 3.9506 feet

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

with btw u said 100pts but it clearly says

i answerd and just got 10pts
