Answer: They are inverses of each other
==========================================================
Explanation:
We'll need to compute h(f(x)) and f(h(x)) to see if we get x each time.

and,

Both composite functions lead to x each time.
The equations h(f(x)) = x and f(h(x)) = x being true means each function is the inverse of the other.
This is a triangular prism.
The lateral faces are triangles; this means that the two bases are parallel to one another. This makes it a prism instead of a pyramid.
The bases being triangles makes it a triangular prism.
Answer:
94°
Step-by-step explanation:
it is a similar triangle and corresponding angles of similar triangles are equal. and interior angles of triangles always equal to 180°
Answer:

Step-by-step explanation:
We have the four thickest books from the line plot given by
Two books of
inch thick and the two books of
inch thickness.
So when the two
inch thick book is being piled on the top of a
inch thick books.
Therefore, the total thickness of the pile of books is given by :



Therefore, the thickness of the pile is
.
