c=6,9

To find the dilation of a shape centered at the origin by a scale factor of \(\frac{1}{3}\), we multiply each coordinate of the shape by the dilation factor.

Given the points:

  • \( A(3, 0) \)
  • \( B(9, 0) \)
  • \( C(6, 9) \)

We perform the dilation for each point as follows:

  1. For point \( A(3, 0) \): \[ A' = \left( 3 \cdot \frac{1}{3}, 0 \cdot \frac{1}{3} \right) = (1, 0) \]

  2. For point \( B(9, 0) \): \[ B' = \left( 9 \cdot \frac{1}{3}, 0 \cdot \frac{1}{3} \right) = (3, 0) \]

  3. For point \( C(6, 9) \): \[ C' = \left( 6 \cdot \frac{1}{3}, 9 \cdot \frac{1}{3} \right) = (2, 3) \]

Thus, the coordinates of the dilated shape are:

  • \( A'(1, 0) \)
  • \( B'(3, 0) \)
  • \( C'(2, 3) \)

These are the points of the shape after applying the dilation of \(\frac{1}{3}\).
