Question

4

Select the correct answer.
A triangle with vertices at A(0, 0), B(0, 4), and C(6, 0) is dilated to yield a triangle with vertices at A'(0, 0), B'(0, 10), and C'(15, 0). The origin is the
center of dilation. What is the scale factor of the dilation?
O A. 1.5
О в. 2
O Cc. 2.5
OD. 3

Answer 1

C. 2.5

Explanation:

B (0,4) --> B' (0,10)

4 * 2.5 = 10

`(10)/(4) = 2.5`

C (6,0) --> C' (15,0)

6 * 2.5 = 15

`(15)/(6) = 2.5`

Scale factor = 2.5
