Answer:

Step-by-step explanation:

In a function, one x-value must have just one y-value assigned to it. So in short, C is the only table that does not represent a function because it has two values of Y (-3, and -1) for one value of x (1).

What is the area of a regular polygon with 100 sides and a perimeter of 100 units?

PolarNik [594]

Now, if the regular polygon has 100 sides, and the perimeter is 100 units, that simply means that each side is 1 unit, foot, meter, else.

so, we know each side is 1 unit long, and we know there are 100 sides,

$\bf \textit{area of a regular polygon}\\\\
A=\cfrac{1}{4}ns^2cot\left( \frac{180}{n} \right)\quad 
\begin{cases}
n=\textit{number of sides}\\
s=\textit{length of a side}\\
\frac{180}{n}=central~angle\\
\qquad~~ in~degrees\\
----------\\
n=100\\
s=1
\end{cases}
\\\\\\
A=\cfrac{1}{4}\cdot 100\cdot 1^2\cdot cot\left( \frac{180}{100} \right)\implies A=25cot\left(\frac{9}{5}^o \right)
\\\\\\
A\approx 795.51289884$

A neighbor needs to put up a square fence around her garden to keep the deer out. If the area is 500 square feet, how much fence

Maurinko [17]

Let's say side length is s.
s*s = 500, so s = √500.

4 sides needed, total length thus 4*s.

4√500 ≈ 89.4
