To find: The scale factor of the dilation.

Answer to Problem 16PT
The scale factor is 52 .
Explanation of Solution
Given information: The given information is:
Calculation:
The scale factor is the ratio of a length on the image to a corresponding length on the preimage.
An enlargement is dilation with k>1 ; that is, the image is larger than the preimage.
A reduction is dilation with 0<k<1 ; that is, the image is smaller than the preimage
The distance between the vertices (−4,0) and (−6,0) for A is −4−(−6)=2 .
The distance between the vertices (−1,0) and (−6,0) for B is −1−(−6)=5 .
The scale factor is 52 .
Therefore, the scale factor is 52 .

- Decomposition geometry: Mary is making a decorative yard space with dimensions as shaded in green (ΔOAB).Mary would like to cover the yard space with artificial turf (plastic grass-like rug). Mary reasoned that she could draw a rectangle around the figure so that the point O was at a vertex of the rectangle and that points A and B were on sides of the rectangle. Then she reasoned that the three smaller triangles resulting could be subtracted from the area of the rectangle. Mary determined that she would need 28 square meters of artificial turf to cover the green shaded yard space pictured exactly.arrow_forward7. 11 m 12.7 m 14 m S V=B₁+ B2(h) 9.5 m 16 m h+s 2 na 62-19 = 37 +, M h² = Bu-29arrow_forwardwhat would a of a interscribed angle be with an arc of 93 degrees and inside abgles of 111 and 98arrow_forward
