I think step five is correct but no sure
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

Answer:
<h2>V = 27m³</h2>
Step-by-step explanation:
We know: All faces of a cube are squares.
The formula of an area of a square with a side <em>s</em>:
<em>A = s²</em>
We have <em>A = 9m²</em>
Substitute:
<em>s² = 9 → s = √9 = 3 m</em>.
The formula of a volume of a cube with an edge <em>s</em>:
<em>V = s³</em>
Substitute:
<em>V = 3³ = 27 m³</em>
