Answer:
1.5
Step-by-step explanation:
The average rate of change is 1.5
when x=0 , the value of y =1
when x=2 the value of y = 4
<em>average rate of change formula = </em>
a= 0 , f(a)=1
b=2, f(b)= 4
4 - 1 / 2 - 0 = 3/2 = 1.5

Step-by-step explanation:
Answer: The height of the model on the right is 22.5 cm .
Step-by-step explanation:
We can see that , the given different models of the same triangular-shaped garden are similar.
For the first model 1 cm = 3.75 m
whereas for the second model 1 cm = 2.5 m
Now , the constant rate of proportion for this (k) = 
Now , if height of the model on the left is 15 cm , then the height of the model on right = 15 x k
= 15 x 1.5
= 22.5 cm
Hence, the height of the model on the right is 22.5 cm .
