Answer:

The scale factor is \frac{1}{2}.

Step-by-step explanation:

The given rule of dilation is

D_{O,K}=(10,0)\rightarrow (5, 0)

It means the  figure is dilated by scale factor K with center at origin.

If a figure dilated by scale factor K  center at origin, then the scale factor is

K=\frac{\text{x-coordinate of image}}{\text{x-coordinate of preimage}}

The x-coordinate of image is 5 and the x-coordinate of preimage is 10. So, the scale factor is

K=\frac{5}{10}

K=\frac{1}{2}

Therefore the scale factor is \frac{1}{2}.
