Answer:
From the given graph:
the coordinates of triangle RST are;
R= (2, 1),
S= (2,-2),
T= (-1,-2)
Given: Scale factor = 
and center of dilation at (2,2)
The mapping rule for the dilation applied to the triangle as shown below:
; where k represents the scale factor i.e, 
or we can write it as ;
For R=(2, 1)
The image R' = 
⇒ R'= 
Similarly for S= (2, -2) and T= (-1,-2)
therefore, the image of S'= 
⇒ S'= 
The image of T' =
⇒T' = 
Now, labelling the image of triangle R'S'T' as shown in the figure given below
Answer:
15 m.
Step-by-step explanation:
If the figures are similar then the ratio of their heights is
∛128 / ∛250
= 0.8.
So 0.8 = 12/ h where h is the height of figure 1,
h = 12 / 0.8
= 15 m.
Answer: Simplifying ratios is just like simplifying fractions. Think of ratios as fractions. You divide a number that both numerator and denominator can be divided by.
<u>Example</u>
5/10 = 1/2
How did we get 1/2? Simple! You divide the numerator and denominator by 5.
5/10÷5/5=1/2
You do the same for ratios but the only difference is instead of putting a fraction bar (/) you put a colon (:)
Let's try another example but with a ratio!
<u>Example</u>
5:10 = 1:2
How did we get 1:2? Simple! Again we divided by 5 just like we did with the fraction example! So really ratios are just like fractions!
5:10÷5:5=1:2
<u>Remember</u>
The fraction bar is /
The ratio bar is :
Ratios are just like fractions but the symbol can sometimes trick people.
