Answer:
Geometric sequence
=54(2/3)^(n-1)
Step-by-step explanation:
Given that a ball is bounced and get up and again hits the ground and bounces up, and so on.
The first height after first hit = 54 inches
Next second peak = 36 inches
III peak = 24 inches
The second peak is 2/3 of first height
and third peak is 2/3 of second height
Thus there is a pattern of geometric sequences such that each peak is 23 of initial peak
IN general nth peak = 54(2/3)^(n-1)
Answer:
B. y = -5x -2
Step-by-step explanation:
Fill in the given values in the form ...
y = (slope)x + (y-intercept)
y = -5x +(-2)
y = -5x -2 . . . . simplify; matches choice B
Answer:
its A 22%
Step-by-step explanation:
Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
