Question

ERROR ANALYSIS Describe and correct the error in finding the scale factor of the dilation.​

Answer 1

k = 2

Explanation:

A dilation is a type of transformation that changes the size of the pre-image without changing its shape.

The scale factor of dilation is found by using the ratio of new length to the original length.

Therefore, to find the scale factor of a dilation, divide the measure of a side of the image by the measure of the corresponding side of the pre-image.

Therefore, the correct calculation for finding the scale factor of the dilation is:

`\boxed{\begin{aligned}k&=(4)/(2)\\\\&=2\end{aligned}}`
