To perform a dilation centered at the origin with a scale factor of \(\frac{1}{5}\), you'll multiply each coordinate of the vertices by the scale factor.
The original coordinates are:
- \( F(-5, -10) \)
- \( G(0, -10) \)
- \( H(3, 0) \)
Now, we apply the scale factor of \(\frac{1}{5}\):
1. For point \( F \):
\[
F' = \left(-5 \cdot \frac{1}{5}, -10 \cdot \frac{1}{5}\right) = \left(-1, -2\right)
\]
2. For point \( G \):
\[
G' = \left(0 \cdot \frac{1}{5}, -10 \cdot \frac{1}{5}\right) = \left(0, -2\right)
\]
3. For point \( H \):
\[
H' = \left(3 \cdot \frac{1}{5}, 0 \cdot \frac{1}{5}\right) = \left(\frac{3}{5}, 0\right)
\]
Thus, the coordinates of the vertices after the dilation are:
- \( F'(-1, -2) \)
- \( G'(0, -2) \)
- \( H'\left(\frac{3}{5}, 0\right) \)
The original coordinates are:
- \( F(-5, -10) \)
- \( G(0, -10) \)
- \( H(3, 0) \)
Now, we apply the scale factor of \(\frac{1}{5}\):
1. For point \( F \):
\[
F' = \left(-5 \cdot \frac{1}{5}, -10 \cdot \frac{1}{5}\right) = \left(-1, -2\right)
\]
2. For point \( G \):
\[
G' = \left(0 \cdot \frac{1}{5}, -10 \cdot \frac{1}{5}\right) = \left(0, -2\right)
\]
3. For point \( H \):
\[
H' = \left(3 \cdot \frac{1}{5}, 0 \cdot \frac{1}{5}\right) = \left(\frac{3}{5}, 0\right)
\]
Thus, the coordinates of the vertices after the dilation are:
- \( F'(-1, -2) \)
- \( G'(0, -2) \)
- \( H'\left(\frac{3}{5}, 0\right) \)
