Answer:

The letter has rotation symmetry only

Step-by-step explanation:

This is because if you rotate N by 360 degrees, it would be the same shape as the it was the first time. It can't be reflection symmetry because If you cut it in half it isn't the same both sides.

Simplify 13 over the quantity of negative 3 plus 2i.

jasenka [17]

$\frac{13}{(-3+2i)}$

To simplify we need to rationalize it. which can be done by multiplying composite of denominator. That is multiply by -3-2i

$=\frac{13}{(-3+2i)}*\frac{(-3-2i)}{(-3-2i)}$

Now multiply numerator with numerator and denominator with denominator

$=\frac{(-39-26i)}{(-3)^2-(-2i)^2}$

$=\frac{(-39-26i)}{9-(4i^2)}$

$=\frac{(-39-26i)}{9-(4(-1))}$

$=\frac{(-39-26i)}{9-(-4)}$

$=\frac{(-39-26i)}{9+4}$

$=\frac{(-39-26i)}{13}$

$=-3-2i$

Hence final answer is $=-3-2i$

Need to know the population in 2015

Margarita [4]

$\bf P=1110.9e^{kt}\quad 
\begin{cases}
P=1200 &\textit{in thousands}\\
t=2 &\textit{in 2002}
\end{cases}\implies 1200=1110.9e^{k2}
\\\\\\
\cfrac{1200}{1110.9}=e^{2k}\implies ln\left( \frac{1200}{1110.9} \right)=ln(e^{2k})\implies ln\left( \frac{1200}{1110.9} \right)=2k
\\\\\\
\cfrac{ln\left( \frac{1200}{1110.9} \right)}{2}=k\implies 0.0385755\approx k\implies 0.0386\approx k\\\\
-------------------------------\\\\$

$\bf P=1110.9e^{0.0386t}\qquad 
\begin{cases}
t=14\\
\textit{year 2015}
\end{cases}\implies P=1110.9e^{0.0386\cdot 14}
\\\\\\
P\approx 1907.0747\implies about\ 1,907,075\textit{ once rounded up}$
