Since it's a Trapezoid with its non - parallel sides equal to one another,

[ By forming co - interior angle pair ]



Now, similarly,



Similarly,



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.
Answer:
((3+5)/2,(6+11)/2)=(4,8.5)
Answer:
282.74in 2
Step-by-step explanation:
r Radius = 5in
h Height = 4in
Answer:
The standard deviation of the sample mean is
Step-by-step explanation:
From the question we are told that
The mean is 
The standard deviation is 
The sample size is 
Generally the standard deviation of the sample mean is mathematically represented as

substituting values
