The vertices of a trapezoid are shown below.

(0 , 6), (6 , 12), (6 , 9), (0 , 12)

Which of the following points is a vertex for the image produced by a dilation about the origin with a scale factor of 1/2?
A.
(0 , 6)

B.
(8 , 14)

C.
(12 , 24)

D.
(3 , 0)
To find the image produced by a dilation about the origin with a scale factor of 1/2, we need to multiply the coordinates of each vertex by the scale factor.

The coordinates for the given vertices are:
(0, 6), (6, 12), (6, 9), (0, 12)

For a scale factor of 1/2, we multiply each coordinate by 1/2:

(0 * 1/2, 6 * 1/2) = (0, 3)
(6 * 1/2, 12 * 1/2) = (3, 6)
(6 * 1/2, 9 * 1/2) = (3, 4.5)
(0 * 1/2, 12 * 1/2) = (0, 6)

The coordinates for the image are:
(0, 3), (3, 6), (3, 4.5), (0, 6)

Among the given options, the vertex (3, 6) matches the coordinates of the image. Therefore, the correct answer is:

B. (3, 6)
