Point C is the center of dilation. Line segment B A is dilated to create line segment B prime A prime. The length of C A is 4. The length of A A prime is 16. What is the scale factor of the dilation of line segment BA?

Step-by-step explanation:

Given

See attachment for figure

Required

The scale factor (k)

Since point C is the center of dilation, the scale factor (k) is calculated using:

So, we have:

$18 was the price of the t-shirt

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
