Answer:

5^2+11^2=13^2 is the answer. However, once you add the 25 and 121 together(the squares of 5 and 11), which is 146, you then need to square root the 146 to get C.

1) -10m(-3 +3m) – 5(8m – 6)

Juliette [100K]

- 30m^2 - 10m + 30

distribute your negative 10, you will first get 30m, then - 30m^2.

next distribute the negative 5, you will get - 40m, then 30.

combine like terms, and make sure its in standard form, - 30m^2 - 10m + 30

What is the answer to this calculus problem???<br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7Bd%7D%7Bdx%7D%20%28e%20%7B%7D%5E

Answer:

see explanation

Step-by-step explanation:

Differentiate using the product rule

Given y = f(x)g(x), then

$\frac{dy}{dx}$ = f(x). g'(x) + g(x). f'(x)

here f(x) = $e^{x}$ ⇒ f'(x) = $e^{x}$

g(x) = cosx ⇒ g'(x) = - sinx

Hence

$\frac{dy}{dx}$ = $e^{x}$ (- sinx) + cosx $e^{x}$

= $e^{x}$ cosx - $e^{x}$ sinx

Identify the area of a regular hexagon with side length 14 in. rounded to the nearest tenth.

kakasveta [241]

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

make sure your calculator is in Degree mode
