Answer:
0.78125 m
Step-by-step explanation:
First term of this geometric series is 50 m, and the common ratio is 1/2.
Thus, a(n) = (50 m)(1/2)^(n-1)
After the 7th bounce, the ball will reach a height of a(7) = (50 m)(1/2)^(7 - 1), or
a(7) = 50 / (2^6) m = 0.78125 m

Answer:
$129
Step-by-step explanation:
Let us represent:
Cost Adult tickets = x
Cost Children's tickets = y
The total cost of ticket = C =
A family goes to an amusement park adult tickets cost $21 children under 10 years of age pay $15
C = $21 × x + $15 × y
C = 21x + 15y
The total cost of 4 adult tickets and 3 children's tickets is calculated as:
C = 21 × 4 + 15 × 3
C = 84 + 45
C = $129
