The side lengths of a rectangle are all multiplied by 5. What happens to its perimeter?
stiv31 [10]

Answer:

The perimeter is multiplied by 5.

Step-by-step explanation:

Perimeter of a rectangle:

The perimeter of a rectangle with sides l and w is given by:

P = 2(l + w)

The side lengths of a rectangle are all multiplied by 5.

This means that l = 5l, w = 5w. So

P_M = 2(5l + 5w) = 2*5(l+w) = 10(l + w)

What happens to its perimeter?

The rate is:

\frac{P_M}{P} = \frac{10(l+w)}{2(l+w)} = 5

The perimeter is multiplied by 5.

The figure shows the graphs of three functions. One is the position function of a car, one is the velocity of the car, one is it
Anika [276]

a) Is the twitch - initial positive twitch or sudden movement, which is what makes the car jolt into action.

b) is the acceleration - graph shows the acceleration and deceleration of the car.

c) is the velocity - starts at 0 and increases until the car travels at its right speed.

d) is the position - assuming that the car is going on only one direction. This graph is the only one that does not go back to the x-axis.

Find (w² + 1)(w³ - w + 1).
Citrus2011 [14]

Answer:

Product is w^5+w^2-w+1

Step-by-step explanation:

Given: (w^2+1)(w^3-w+1)

Simplify the product of polynomial.

It is product of binomial with trinomial.

\Rightarrow (w^2+1)(w^3-w+1)

\Rightarrow w^2(w^3-w+1)+1(w^3-w+1)        (Distributive property)

\Rightarrow w^2\cdot w^3-w^2\cdot w+w^2\cdot 1+w^3-w+1  (Distributive property)

\Rightarrow w^5-w^3+w^2+w^3-w+1             (combine like term)

\Rightarrow w^5+w^2-w+1

Product is w^5+w^2-w+1
