Answer:


Step-by-step explanation:
<u>Composite Function</u>
Suppose f(x) and g(x) are real functions, the composite function named
is defined as:

The composite function can be found by substituting g into f.
We are given these functions:



Find:
a) h(g(x))
Substituting g into h:

b) h(g(f(x))
First we find g(f(x)):

Operating:

Simplifying:

Now find h(g(f(x)) replacing the above equation into h:

Simplifying and rearranging:


Answer:
121, 64, and 16
Step-by-step explanation:
A perfect square is the product of a rational number multiplied by itself. So 11*11=121, 8*8=64, and 4*4=16
Answer:

Step-by-step explanation:
So just divide the areas by the length:

And that is your width.
From the graph at x = 0, y = 0
Check1:
y = cosx
0 = cos(0)
0 = 1
therefore, this is not the function
Check2:
y = sinx
0 = sin(0)
0 = 0
therefore, this is the function
Conclusion:
the function in the graph is y = sinx
I think that she started with 10.. I'm not 100% sure, though
