$\bf \textit{area of a regular polygon}\\\\
A=\cfrac{1}{4}ns^2\ cot\left( \frac{180}{n} \right)\qquad 
\begin{cases}
s=\textit{length of a side}\\
n=\textit{number of sides}\\
\frac{180}{n}=\textit{angle in degrees}\\
----------\\
s=14\\
n=6\leftarrow hexagon
\end{cases}
\\\\\\
A=\cfrac{1}{4}\cdot 6\cdot 14^2\cdot cot\left( \frac{180}{6} \right)$

make sure your calculator is in Degree mode

Please help me solve number 14 and 15

Charra [1.4K]

Answer:

Step-by-step explanation:

Similarity property,

" If the two triangles are similar then their corresponding sides will be proportional."

14). If ΔPQR ~ ΔUVW,

$\frac{PQ}{UV}=\frac{QR}{VW}=\frac{PR}{UW}$ [Statement}

$\frac{15}{10}=\frac{9}{6}=\frac{6}{4}$

$\frac{3}{2}=\frac{3}{2}=\frac{3}{2}$ [True}

Therefore, ΔPQR ~ ΔUVW [Theorem - SSS]

15). If ΔFHE ~ ΔDHG,

$\frac{EH}{HG}=\frac{HF}{DH}$ [Statement]

$\frac{24}{6}=\frac{36}{9}$

4 = 4

Therefore, ΔFHE ~ ΔDHG [Theorem - AA]

Show all steps. Simplify using order of operations plz help me asap

Nina [5.8K]

Answer:

$6$

Step-by-step explanation:

Work from the inside-out following PEMDAS.

$3^2=9$

$9-4=5$

$10+(5)=15$

So, now we need to calculate 90/15.

$90/15=18/3=6$

So, the answer is $\boxed{6}$ and we're done!

Write the linear system:

notsponge [240]

Answer:

(See explanation for further details).

Step-by-step explanation:

C) The linear system is:

$(-1)^{2} \cdot a + (-1)\cdot b + c = 5$

$c = - 4$

$(4)^{2}\cdot a + (4)\cdot b + c = 0$

After some algebraic handling:

$a - b + c = 5$

$c = -4$

$16\cdot a + 4\cdot b + c = 0$

By direct substitution:

$a - b - 4 = 5$

$16\cdot a + 4\cdot b - 4 = 0$

$a - b = 9$

$4\cdot a + b = 1$

$a = 9 + b$

$4\cdot (9+b)+b = 1$

$36 + 5\cdot b = 1$

$5\cdot b = -35$

$b = -7$

$a = 2$

D) The parameter values are: $a = 2$ , $b = -7$ , $c = -4$

E) The quadratic equation is $y = 2\cdot x^{2} - 7\cdot x -4$

18. Does the rule y=-5xº represent an exponential function? (1 point)<br><br> Ono<br><br> Oyes

Nikolay [14]

Answer:

No

Step-by-step explanation:

Given function is $y=5x^0$ .

We need to find does this represents an exponential function?

Let us see what does an exponential function means?

A function is said to be an exponential function, when $x$ is in the exponent.

In our problem it is $y=5x^0$ . Here we can see $x$ is raised to zero. That is a power function.

In power function $x$ raised to a definite power.
