A ball is dropped from a height of 50 feet. The function f(x) = 50(0.6)x gives the height in feet of feet of each bounce, where x is the bounce number. What is the height of the third bounce to the nearest tenth of a foot?

Answers

Answer:

The height of the third bounce is 10.8 feet

Step-by-step explanation:

Let us solve the question

∵ A ball is dropped from a height of 50 feet

∵ The function f(x) = 50[tex](0.6)^{x}[/tex] gives the height in feet of each bounce

∵ x is the bounce number

∵ We need to find the height of the third bounce

∴ x = 3

→ Substitute x by 3 in the function above

∵ f(3) = 50(0.6)³

∴ f(3) = 50(0.126)

∴ f(3) = 10.8

∴ The height of the third bounce is 10.8 feet

The distance between X and Y is 6 1/2 units. Which number could represent the point Y?

Answers

Answer:

[tex]\huge\boxed{\sf 3.5}[/tex]

Step-by-step explanation:

Distance = [tex]\sf 6 \frac{1}{2} \ units = 6.5 \ units[/tex]

Here X is -3

So,

Point Y = -3 + 6.5 = 3.5

[tex]\rule[225]{225}{2}[/tex]

Hope this helped!

~AH1807

Answer:

B

Step-by-step explanation:

so we know x is -3

we also know that the number has to be 6.5 units away from -3

so, -3 plus 6.5 is 3.5

-3 minus 6.5 is -9.5

Either 3.5 or -9.5 would work but 3.5 is the only listed option, so the answer is B
