Answer:
to simplify 2m - [n - (m - 2n)], you have to go though this steps:
2m - [n - (m - 2n)] = 2m - [n - m + 2n] = 2m - n + m - 2n = 3m - 3n
Step-by-step explanation:
What does the number 0.7 represent?
The ball bounces to 30% of its previous height with each bounce.
The height at which the ball bounces at the nth bounce is 0.3 feet.
The ball bounces to 70% of its previous height with each bounce.
The height from which the ball was dropped at the nth bounce is 0.7 feet.
Answer:
The ball bounces to 70% of its previous height with each bounce.
Step-by-step explanation:
In physics terminology, the number 0.7 is the coefficient of restitution. It is the ratio of the height of bounce (n+1) to the height of bounce (n).
The meaning of the number is that the ball bounces to 70% of the height of the previous bounce.
Answer:
The ball bounces to 70% of its previous height with each bounce.
Step-by-step explanation:
A ball is dropped from a certain height. The function below represents the height f(n), in feet, to which the ball bounces at the nth bounce:
f(n) = 9(0.7)n
The number 0.7 represents that the ball bounces to 70% of its previous height with each bounce.
Answer:
Step-by-step explanation:
Perimeter is the sum of the side lengths
If polygon A has perimeter
Then polygon B has perimeter of
Since P = 144
We can write a ratio comparing the sides of both polygons.
A:B = 3:1
Since we know that 144 is the perimeter for polygon A, we can substitute it.
144:B = 3:1
~Simplify
144 = 3B
Divide 3 to both sides
48 = B
Therefore, the perimeter of B is 48 units.
Best of Luck!
Answer:
the square root of 16 is 4
Step-by-step explanation:
2x – y = –2
x + 2y = 24
x – 2y = –16
Answer: it would be shifted up
