The single dilation of the shape is a dilation by a scale factor of 1.5 with center R
<h3>How to determine the dilation rule?</h3>
From the graph, we have the center of dilation to be point R.
This is so because R = R'
Also, we have:
R = (-1, -4)
S = (2, 0)
S' = (3.5, 2)
Calculate the distance RS and RS' using
This gives
Divide RS' by RS to determine the scale factor (k)
k = 7.5/5
k = 1.5
Hence, the single dilation of the shape is a dilation by a scale factor of 1.5 across point R

Radius, Diameter and Circumference
The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.

Answer:
1 4 /15
Step-by-step explanation:
3/5 + 2/3
the first step is to get a common denominator, 15
3/5 * 3/3 + 2/3 * 5/5
9/15 + 10/15
19/15
new we need to change it to a mixed number
15 goes into 19 one time with 4 left over
1 4/15
