Answer:</h2><h3>b. n is odd</h3><h2>
Step-by-step explanation:</h2>
In this problem, we assume that
is a whole number. The definition of inverse functions tells us that a function
has an inverse function if and only if the function is one-to-one, that is, if there is no any horizontal line intersecting the graph of
at more than one point. This only happens if
is odd. This is called the Horizontal Line Test for Inverse Functions. So let's take two examples:
FIRST:

Since n is even, an horizontal line will pass through two points as indicated in the first figure below.
SECOND:

Since n is odd, an horizontal line will pass through just one point as indicated in the second figure below.
Answer:
16 feet
Step-by-step explanation:
The geometry of the problem can be modeled by a right triangle. The Pythagorean theorem tells us the relationship between the various distances.
EH² +HF² = EF²
EH² + 12² = 20²
EH² = 400 -144
EH = √256 = 16
The hook is 16 feet below Edna.
Answer:
I agree it's annoying!!!
Step-by-step explanation:
I think the people who just spam questions are just lazy and they have nothing else to do with their lives. So they try to make themselves feel better by annoying other people. I hope you are having a good day other than people spamming questions!
