Answer:
where is the rest of the question?
Step-by-step explanation:
In this question, the thing that needs to be found is the number whose 20% would be 18. The information's required for getting to the solution are already provided in the question. based on those given information's, the answer can be deduced very easily.
Let us assume the unknown number to be = x
Then
(20/100) * x = 18
x/5 = 18
x = 18 * 5
= 90
so the unknown number in the question is 90. I hope the procedure is clear enough for you to understand.

Answer:
A) The graph of g(x) is shrunk vertically by a factor of 1/9
Step-by-step explanation:
The given graph g(x) = 1/9√x
f(x) = √x
The altitude of g(x) = 1/9
The altitude of f(X) = 1
When comparing the graph of g(x) with f(x), the graph of g(x) shrunk by 1/9 because of the altitude.
Here with I have attached the graph.
Therefore, answer: A) The graph of g(x) is shrunk vertically by a factor of 1/9
Thank you.
