Answer: 4
Step-by-step explanation: 18/6 =3 so do 12/3 and it will give you 4
Try this way:
Note,
1. that 16/2=8 it means 10/2=5.
2. that 10*3=30, it means 16*3=48
Finally for whole table:
================
forks: 16 8 48
================
spoons: 10 5 30
================
By just changing the x and numbers you can solve it:
-4x=-8 => x=2
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
