Answer:
From the graph: we have the coordinates of RST i.e,
R = (2,1) , S = (2,-2) , T = (-1,-2)
Also, it is given the scale factor and center of dilation C (1,-1)
The mapping rule for the center of dilation applied for the triangle as shown below:
or
or
Now,
for R = (2,1)
the image R' = or
⇒ R' =
For S = (2, -2) ,
the image S'= or
⇒ S' =
and For T = (-1, -2)
The image T' = or
⇒ T' =
Now, label the image of RST on the graph as shown below in the attachment:
Answer:
81.39% increase.
Step-by-step explanation:
Given: There is change in number from 43 to 78.
First lets find the amount of change or difference in number.
Difference in number=
∴ Difference in number show that there is an increase of 35 number.
Now, finding the percent change in the number.
Percent=
⇒ Percent change in number=
∴ 81.39% increase in the number.
