For right triangles, tangent is opposite length over adjacent length

tangent of 34 is x over 20 because x is the opposite side and 20 is the adjacent

tan(34) = x / 20
x = 20tan(34)
To three decimal places, a decimal approximation is
x ≈ 13.490

Answer:

F'=12.1243557 N

Step-by-step explanation:

Let the horizontal component of force he is pulling with be F' Newtons and the force applied be F Newtons.

$\therefore \cos \theta = \frac{Horizontal \: Force}{Force \: applied}$

$\therefore \cos \theta = \frac{F'}{F}$

$\therefore F'=F\cos \theta$

$\therefore F'=14.\cos 30\degree$

$\therefore F'=14.\frac{\sqrt 3}{2}$

$\therefore F'=7\sqrt 3$

$\therefore F'=12.1243557 \: N$

11000 is compounded semiannually at a rate of 12% for 21 years. Find the total amount in the compound interest account

marishachu [46]

$\bf ~~~~~~ \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\dotfill &\$11000\\
r=rate\to 12\%\to \frac{12}{100}\dotfill &0.12\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{semiannually, thus twice}
\end{array}\dotfill &2\\
t=years\dotfill &21
\end{cases}$
