Final answer:
After dilating Point A (5,15) with a scale factor of 0.20, the new coordinates of A' are (1, 3).
Step-by-step explanation:
When a point is dilated with a scale factor, the coordinates of the point are multiplied by that scale factor. Given that Point A (5,15) is being dilated with a scale factor of 0.20, you can find the new coordinates for A' by multiplying each original coordinate by 0.20.
To calculate:
A'x = original x-coordinate × scale factor = 5 × 0.20 = 1
A'y = original y-coordinate × scale factor = 15 × 0.20 = 3
Therefore, the coordinates of point A' after dilation are (1, 3).
