When you dilate the image by 3, you would multiply each value by 3. Since it's center is around 0, we really don't have to worry about much else.
-1*3= -3
-2*3= -6
0*3= 0
The new set of points are (-3,-6,0)
I hope this helps!

Answer:
26.13 ft²
Step-by-step explanation:
The total area is twice the area of the right triangles plus half the area of a circle of radius 3 ft.
Semicircle area = (1/2)(πr²)
semicircle area = (1/2)(3.14)(3 ft)² = 14.13 ft²
The area of the two right triangles is ...
total triangular area = (3 ft)(4 ft) = 12 ft²
Then the area of the figure is ...
figure area = semicircle area + total triangular area
= 14.13 ft² + 12 ft² = 26.13 ft²
Answer:
Step-by-step explanation:
<u>Use the ratio of corresponding sides of similar triangles:</u>
- 25/x = x / 144
- x² = 25*144
- x = √25√144
- x = 5*12
- x = 60
6 1/2 times 5=32.5
36-32.5=3.5
