The area of a rectangle is 100cm2. After a dilation, the area is 25cm2. What is the scale factor? You may give your answer as a fraction or decimal

1/4 or 0.25

Step-by-step explanation:

Initial area of the rectangle = 100cm²

After dilation, the area reduces to 25cm²

This shows that there is reduction in the size of the rectangle.

The ratio of the final area to the initial area will give the scale factor.

Ratio = 25cm²:100cm²

= 25/100

= 1/4

The scale factor is therefore 1/4 or 0.25

2

step-by-step explanation:

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
