RST is dilated about the origin, 0, to create R’S’T. Point R is located at (3,9) and point R’ is located at (1.2, 3.6). Which scale factor was used to perform the dilation?

Respuesta :

Answer:

0.4

Step-by-step explanation:

Since the dilatation is about the origin, then dividing the coordinates of the image R' by the coordinates of the original point R gives the scale factor

scale factor = [tex]\frac{1.2}{3}[/tex] = [tex]\frac{3.6}{9}[/tex] = 0.4
