Polygon ABC D is dilated rotated and translated to form polygon a prime be prime see prime see the prime the endpoints of a B are at zero and -7 and eight and eight in the endpoints of a prime be prime or at six and -6 and two and 1.5 what is the scale factor of the dilation

Answer:

[tex]\dfrac12[/tex]

Step-by-step explanation:

The endpoints AB are at (0,-7) and (8,8)

The endpoints A'B' are at (6,-6) and (2,1.5)

To determine the scale factor of the dilation, we determine the lengths of the segments AB and A'B' using the distance formula.

[tex]AB=\sqrt{(8-0)^{2}+(8-(-7))^{2}}\\=\sqrt{8^{2}+15^{2}}\\=\sqrt{64+225}\\=\sqrt{289}\\AB=17[/tex]

[tex]A^{\prime} B^{\prime}=\sqrt{(2-6)^{2}+(1.5-(-6))^{2}}\\=\sqrt{4^{2}+7.5^{2}} \\=\sqrt{16+56.25}\\=\sqrt{72.25}\\A'B'=8.5[/tex]

Length of AB in the pre-image = 17 Units

Length of AB in the image, A'B'=8.5 Units

Therefore, the scale factor of the dilation

= [tex]\dfrac{8.5}{17}=\dfrac12[/tex]
