Answer: 1/3
Step-by-step explanation:
We know that after dilation with scale factor k the coordinates of pre-image (x,y) map to (kx,ky) of the image.
From the given graph, the coordinate of A =(9,4) and the coordinate of A' (3,2)
Then
and 

Therefore, the scale factor of the dilation is 1/3.
2x+5=12
Subtract 5 from both sides
=2x=7
Divide by 2
X=2/7
Answer:
y=sin(°/3) means that y equals the sine of a given degree divided by 3.
D=2r=2·4=8 cm
A = L² (L=d)
A = 8² = 64 cm²
