Simplify 2m - [n - (m - 2n)]. -3m - n 3m - n -3m - 3n 3m - 3n

Answers

Answer 1

Answer: If you would like to simplify 2m - [n - (m - 2n)], you can do this using the following steps:

2m - [n - (m - 2n)] = 2m - [n - m + 2n] = 2m - n + m - 2n = 3m - 3n

The correct result would be 3m - 3n.

Answer 2

Answer:

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

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

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.

Answers

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.

Polygon A is similar to polygon B the sides of polygon A are three times larger then the corresponding sides of polygon B the perimeter of polygon A is 144 what is the perimeter of polygon B ?

Answers

Answer:

48 units

Step-by-step explanation:

Perimeter is the sum of the side lengths

If polygon A has perimeter

P = a+b+c+d for example

Then polygon B has perimeter of

P' = 1/3a+1/3b+1/3+1/3d = 1/3P as each side is 3 times smaller than the corresponding side

Since P = 144

P' = 1/3P = 1/3*144 = 48 units

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.

If y=2x-3 were changed to y=2x+5 , how would the graph of new function compare with the original?

Answers

The new graph would have the same slope (2) as the original one,
but its y-intercept would be [ 5 - (-3) ] = 8 higher.

The new straight line would be parallel to the original straight line,
and they would be 8 units apart everywhere.

Answer: it would be shifted up
