Answer:
2
Step-by-step explanation:


So,
To compose a function with another, substitute the inside function into every place where x appears in the outer function.
For (h * h)(x), substitute h(x) for every x in the outer function, h(x).

For (f * f)(x), substitute f(x) for every x in the outer function, f(x).

Hope this helps!

Answer:
The value of c is 3
Step-by-step explanation:
Here, we want to get the value of c
From the question, we can select a single x-point
when x = 16
f(x) = 2
g(x) = -1
Thus;
g(16) = f(16) - c
-1 = 2 - c
c = 2 + 1
c = 3
Can use right angle angle trigonometry as this is a right triangle
sine is opposite over hypotenuse
sin 60 = BC/AB because opposite to 60 is BC and the hypotenuse is AB.
rearrange for AB
sin 60 = BC/AB
AB sin 60 = BC
AB = BC / sin 60
we are given that BC = 15 in
AB = 15 / sin60
AB = 17.321 in (calculator
can use tangent of 60 degrees to find AC
tangent is opposite over adjacent so
tan(60) = BC / AC
AC tan 60 = BC
AC = BC / tan 60
AC = 15 / tan 60
AC = 8.660 in
