Answer:

H) 2

Step-by-step explanation:

$\frac {\sqrt {1 - \cos^{2}x}}{\sin x} + \frac {\sqrt {1 - \sin^{2}x}}{\cos x}$

= $\frac {\sin x}{\sin x} + \frac {\cos x}{\cos x}$ [since 0 < x < (π/2) and $\sin^{2}x + \cos^{2}x = 1$ ]

= (1 + 1)

= 2

We know that in general,

by $\sqrt {x}$ we mean the positive square root of x only.

$1200.00 is deposited into an account that earns 6.5% interest, which is compounded four times per year. How much money will be

choli [55]

$\bf ~~~~~~ \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$1200\\
r=rate\to 6.5\%\to \frac{6.5}{100}\to &0.065\\
n=
\begin{array}{llll}
\textit{times it compounds per year}
\end{array}\to &4\\
t=years\to &6
\end{cases}
\\\\\\
A=1200\left(1+\frac{0.065}{4}\right)^{4\cdot 6}\implies A=1200(1.01625)^{24}$
