If a ball is dropped from a height of 18 ft the function f(x)=18 (0.75)^xgives the height in feet of each bounce, where x is the bounce number. What will the height of the 7th bounds to the nearest tenth of a foot

f ( 7 ) = 2.4 ft

Step-by-step explanation:

Solution:-

- This is modeled using a geometric sequence function with initial height from which ball is dropped hi = 18 feet, and a decrease in height by 25% after each successive bounce :

                       f ( x ) = 18 (0.75)^x

Where,   x e [ 0 , ∞ ) : The number of bounces.

              f (x) : The maximum height after xth bounce.

- The maximum height reached by the ball after its 7th bounce. So, x = 7:

                        f ( 7 ) = 18 (0.75)^7

                        f ( 7 ) = 2.4027 ft

- To the nearest tenth:

                      f ( 7 ) = 2.4 ft

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
