Question

Which types of dilation are the given scale factors?

Select Expansion or Contraction to correctly describe the type of dilation for each given scale factor.

Answer 1

The scale factor determines whether dilation is an expansion or a contraction.

Step-by-step explanation:

In terms of dilation, the scale factor determines whether the dilation is an expansion or a contraction. If the scale factor is greater than 1, it indicates expansion, which means the size is increasing. If the scale factor is between 0 and 1, it indicates contraction, which means the size is decreasing.

For example, if we have a scale factor of 2, it means the object is expanding, and each dimension of the object is doubled. On the other hand, if we have a scale factor of 0.5, it means the object is contracting, and each dimension of the object is halved.

Answer 2

Any negative number is going to be a contraction.

expansion= bigger dilation
contraction= smaller dilation

Let's use the number 2, for example, to help us solve.

2*-4= -8

-8 is less than -4 since the bigger a negative number something is, the smaller in value it has.

It is a contraction.

2*2.5= 5

5 is bigger than 2.

It is an expansion.

2*2/3= 1 1/3

2 is bigger than 1 1/3.

This is a contraction.

2*-.75= -1.5

2 is bigger than -1.5.

This is a contraction.

I hope this helps!
