The total measure of the inner angles of a shape is determined by the expression;
(n-2)*180° where n is the number of sides.
(3-2)180°
1*180°
180° is the total measure of the inner angles.
To put that as an equation;
180° = 77° + 62° + x°
x = 41°

Well we have the triangle.
We know that a triangle has a total of 180 degrees, right?
So...
We add 77+62=139
180-139=
41 degrees.
Hope this helps!

Complete the equation. (4x)^2(4x)^3(4x)^9=(4x)__ Fill in the blank.

Answer:

4x^{14}

Step-by-step explanation:

in that equation, when you multiply integers with exponents, the integers multiply but the exponents add.

2+3+9 = 14

which means that the awnser is 4x^{14}

How much money should be invested at 5% interest, compounded quarterly, so that 7 years later the investment will be worth $5000

vampirchik [111]

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\to &\$5000\\
P=\textit{original amount deposited}\\
r=rate\to 5\%\to \frac{5}{100}\to &0.05\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{quarterly, four times}
\end{array}\to &4\\
t=years\to &7
\end{cases}
\\\\\\
5000=P\left(1+\frac{0.05}{4}\right)^{4\cdot 7}\implies 5000=P(1.0125)^{28}\\\\\\ \cfrac{5000}{(1.0125)^{28}}=P$
