Identify the area of a regular hexagon with side length 14 in. rounded to the nearest tenth.
kakasveta [241]
\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)

Can you explain how to do this?
ivanzaharov [21]
Hi there! The answer is x = 1

Let's solve this problem step by step!
8(10) {}^{2x}  = 800

First divide both sides of the equation by 8.
10 {}^{2x}  = 100

Now rewrite 100 as a power of 10.
10 {}^{2x}  = 10 {}^{2}

Now we can use the following rule, which basically means that two different exponents of the same base must be the same
{g}^{a}  =  {g}^{b}  \\ a = b



We now get this.
2x = 2



Finally divide both sides by 2.
x = 1



~ Hope this helps you!

negative 1 times the sum of twice a number and 3 is equal to two times the difference of -4 times the number and 3. What is the
zaharov [31]

Answer:

1.5

Step-by-step explanation:

Let the number be denoted as "a"

-1 (2a + 3) = 2 (-4a + 3)

-2a - 3 = -8a + 6

-2a + 8a = 6 + 3

6a = 9

a = 9/6

a = 3/2 = 1.5

A system of equations consists of y = x3 + 5x + 1 and y = x. The equations are equal at approximately x = -0.25, -0.5, 0.5, 0.25
Afina-wow [57]

Answer:

x=-0.25

Step-by-step explanation:

we have

y=x^{3}+5x+1 -----> equation A

y=x -----> equation B

Using a graphing tool-----> to resolve the system of equations

Remember that the solution of the system of equations is equal to the intersection point both graphs

see the attached figure

the solution is x=-0.25
