Question

Find the scale factor of the dilation ( in fraction form , if necessary).(Hint:Scale Factor = Image length preimage length)

Answer 1

Answer:

The scale factor of the dilation is;

$\frac{1}{2}$

Explanation:

Given that;

Scale factor is image length divided by pre-image length;

$\text{ Scale factor=}\frac{\text{ image length}}{\text{Pre image length}}$

From the diagram;

$\begin{gathered} \text{Preimage length = 2 in} \\ \text{image length = 1 in} \end{gathered}$

Applying the above formula;

$\text{Scale factor =}\frac{1\text{ in}}{\text{2 in}}=\frac{1}{2}$

Therefore, the scale factor of the dilation is;

$\frac{1}{2}$
