Divide 9/40 will give you 0.225
Multiply it by 100
= 0.225 x 100 = 22.5%
For a dilation centered around the origin
Dk (x,y) = (kx, ky)
So let's say you have a rectangle PQRS where
P = (0,0)
Q = (4,0)
R = (4,4)
S = (0,4)
To get the dilation of this PQRS to P'Q'R'S' with scale factor 1/4 you multiply every coordinate by 1/4.
P' = (0.0)
Q' = (1,0)
R' = (1,1)
S' = (0,1)
The new cordinates for point q(1,0)
Answer:
19.4 cm
Step-by-step explanation:
Divide the Area by the length to find the width
Y intercept is -7
