If order doesn't matter (e.g. all the positions in the committee are essentially identical) then the number of possible choices is

.

1) Let's simplify those expressions making use of exponents rules:

Note that the exponent outside the parenthesis is 'distributed' over each term inside.
2) Similarly for the second expression we can state that:
Answer:
There are Even, Odd and None of them and this does not depend on the degree but on the relation. An Even function:
And Odd one: 
Step-by-step explanation:
1) Firstly let's remember the definition of Even and Odd function.
An Even function satisfies this relation:

An Odd function satisfies that:

2) <u>Since no function has been given</u>. let's choose some nonlinear functions and test with respect to their degree:



3) Then these functions are respectively even and odd, because they passed on the test for even and odd functions namely,
and
for odd functions.
Since we need to have symmetry to y axis to Even functions, and Symmetry to Odd functions, and moreover, there are cases of not even or odd functions we must test each one case by case.
19.37cm is 74.5% of 26cm so we then we need to take away 19.37 from 26cm that leaves us with 6.63
hope i helped was quite hard just remember the way i did it
Answer:
It should be D if not Than A
