Question

Rectangle QUAD has coordinates Q(0,0) U (0,4) A(7,4) and D(7,0) . Q'U'A'D is the image of QUAD after dilation with center (0,0) and scale factor 7. what are the coordinates of point U'?

Answer 1

Answer:

The coordinates of point U' are (0, 28)

Explanations:

The coordinates of triangle QUAD are:

Q(0, 0)

U(0, 4)

A(7, 4)

D(7, 0)

Center of dilation = (0, 0)

Scale factor = 7

Since the scale factor is 7, the coordinates of all the points in the rectangle Q'U'A'D' will be gotten by multiplying the x and y coordinates by the scale factor, 7

Therefore, the coordinates of the point U' will be :

U' (7x0, 7x4) = U'(0, 28)
