$5326.135 will be his ending balance after one year.

<u>Solution:</u>

Deposited amount = $2,300

Rate of interest = 1.13% per week

A=P\left(1+\frac{r}{n}\right)^{n t}

where A = final amount  

P = principal = 2300

r = interest rate  = 1.13\%=\frac{1.13}{100}=0.0113

n = number of times interest applied per time period  = 52 week

(1 year has 52 weeks)

t = number of time periods elapsed = 1 year

On substituting the values we get,

Amount=2300 \times\left(1+\frac{0.0113}{52}\right)^{52}

\Rightarrow2300\times(\frac{52+0.0113}{52})^{52}\rightarrow2300\times(\frac{52.0113}{52})^{52}\rightarrow2300\times(1.000217)^{52}

On solving we get, \Rightarrow5326.135

Therefore, the amount is $5326.135.

Write the given expression as an algebraic expression in x. tan(2 cos^-1(x))
miv72 [106K]
\bf tan\left[ 2cos^{-1}(x) \right]\implies tan\left[ 2cos^{-1}\left( \frac{x}{1} \right) \right]&#10;\\\\\\&#10;\textit{if we say }cos^{-1}\left( \frac{x}{1} \right)=\theta\textit{  that means }tan\left[ 2cos^{-1}\left( \frac{x}{1} \right) \right]\iff tan(2\theta)\\\\&#10;-----------------------------\\\\&#10;cos^{-1}\left( \frac{x}{1} \right)=\theta\implies cos(\theta)=\cfrac{x}{1}\cfrac{\leftarrow adjacent=a}{\leftarrow hypotenuse=c}\\\\&#10;-----------------------------\\\\&#10;

\bf \textit{again, using the pythagorean theorem to get the opposite side}&#10;\\\\\\&#10;c^2=a^2+b^2\implies \pm\sqrt{c^2-a^2}=b\implies \pm\sqrt{1^2-x^2}=b&#10;\\\\\\&#10;\pm\sqrt{1-x^2}=b\\\\&#10;-----------------------------\\\\&#10;tan(2\theta)=\cfrac{2tan(\theta)}{1-tan^2(\theta)}\implies tan(2\theta)=\cfrac{2\cdot \frac{\pm\sqrt{1-x^2}}{x}}{1-\left( \frac{\pm\sqrt{1-x^2}}{x} \right)^2}&#10;\\\\\\

\bf tan(2\theta)=\cfrac{\frac{\pm2\sqrt{1-x^2}}{x}}{1-\frac{1-x}{x}}\implies &#10;tan(2\theta)=\cfrac{\frac{\pm2\sqrt{1-x^2}}{x}}{\frac{x-1+x}{x}}&#10;\\\\\\&#10;tan(2\theta)=\cfrac{\pm2\sqrt{1-x^2}}{x}\cdot \cfrac{x}{2x-1}&#10;\implies &#10;tan(2\theta)=\cfrac{\pm 2\sqrt{1-x^2}}{2x-1}
