If a superball is bounced from a height of 20 feet, the function
f(x)  20 (0.9)x gives the height of the ball in feet of each bounce,
where x is the bounce number. What will be the height of the
6th bounce? Round your answer to the nearest tenth of a foot.

Complete question:

If a Super ball is bounced from a height of 20 feet, the function F(x) = 20(0.9)ˣ gives the height of the ball in feet of each bounce, where x is the bounce number. What will be the height of the 6th bounce? Round your answer to the nearest tenth of a foot.

The height of the ball after the sixth bounce to the nearest tenth of a foot = 10.6 feet  

Step-by-step explanation:

Function representing the height of a ball in the question

F(x) = 20(0.9)ˣ

x= number of times which the ball has been bounced  In the question, we are given x as 6 times

The height after the 6th bounce is calculated as =  

F(x)= 20(0.9)ˣ

F(x) = 20(0.9)⁶

F(6) = 20 × 0.531441

F(6) = 10.62882 feet

Approximately to the nearest tenth = 10.6 feet.  

Therefore, the height of the ball after the 6th bounce in feet to the nearest tenth is 10.6 feet.

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
