Recall that a dilation with center (0, 0) and scale factor 
maps 
onto 
.
Now, triangle ADE is formed by
Whereas triangle ABC is formed by
In other words, the coordinates of B and C can be obtained by multiplying by 2 the coordinates of D and E.
This means that you get ABC from ADE by dilating with center (0,0) and scale factor 2.

Answer:
6/5=x/15
Step-by-step explanation:
6/5=x/15,where x is hight of the lamp post
x=18
Given:
The graph of a radical function.
To find:
The domain of the given radical function.
Solution:
We know that, domain is the set of input values or we can say domain is the set of x-values for which the function is defined.
From the given graph it is clear that, for each value of x there is a y-value. It means the function is defined for all real values of x. So,
Domain = Set of all real numbers.
Therefore, the correct option is A.
