Triangle ABC has coordinates A (-4, 4), B (4, 8), and C (4, 0). 

a. Find

the coordinates of the vertices of triangle A’B’C after a dilation using a scale factor of 0.75. 

b. Find the coordinates of the vertices of triangle A’B’C after a dilation of triangle A’B’C using a scale factor of 4. 

c. Use the scale factors given in parts (a) and (b) to find the scale factor you could use to dilate triangle ABC to its final image in one step. Explain.

2) If a figure has at least one vertex in every quadrant, will its dilation have at least one vertex in every quadrant? Explain.

3) The length of one side of an original figure is 110 units. The length of the corresponding side of the image figure is 11 units. What is the scale factor of the dilation?

4) You have $45 to buy noisemakers and hats for a party you are hosting. Each noisemaker costs $1 and each hat costs $3.
