Question

figure e is dilated to form figure f. what is the scale factor of the dilation? scale factor =

Explanation:

Step1: Find the length of a corresponding side in both figures

Let's consider the vertical side of figure \(E\) and \(F\). The vertical side of figure \(E\) is \(2\) units (counting the grid - squares). The vertical side of figure \(F\) is \(4\) units.

Step2: Calculate the scale factor

The formula for the scale factor \(k\) of a dilation is \(k=\frac{\text{length of a side in image}}{\text{length of the corresponding side in pre - image}}\). Here, \(k = \frac{4}{2}\)

Answer:

\(2\)
