Compound interest

Posted by Raushan Raj 7 years, 1 month ago

1 answers

Shivam Anand 7 years, 1 month ago

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.

{tex}=2\left\{\frac{\cos\left(90^\circ-32^\circ\right)}{\sin32^\circ}\right\}-\sqrt3\left\{\frac{\cos38^\circ cosec\left(90^\circ-38^\circ\right)}{\tan15^\circ\tan60^\circ\tan\left(90^\circ-15^\circ\right)}\right\}{/tex}
{tex}= 2 \left( \frac { \sin 32 ^ { \circ } } { \sin 32 ^ { \circ } } \right) - \sqrt { 3 } \left\{ \frac { \cos 38 ^ { \circ } \sec 38 ^ { \circ } } { \tan 15 ^ { \circ } \times \sqrt { 3 } \times \cot 15 ^ { \circ } } \right\}{/tex} {tex}\left[\because\;\cos\left(90-\theta\right)=\sin\theta\;,\;\cos ec\left(90-\theta\right)=sec\theta,\;\tan\left(90-\theta\right)=cot\theta\;\right]{/tex}
{tex}= 2 - \sqrt { 3 } \left\{ \frac { \cos 38 ^ { \circ } \times \frac { 1 } { \cos 38 ^ { \circ } } } { \tan 15 ^ { \circ } \times \sqrt { 3 } \times \frac { 1 } { \tan 15 ^ { \circ } } } \right\} = 2 - \frac { \sqrt { 3 } } { \sqrt { 3 } } = 2 - 1 = 1{/tex} {tex}\left[sec\theta=\frac1{\cos\theta},\;cot\theta=\frac1{\tan\theta}\right]{/tex}

therefore, {tex}2\left(\frac{\cos58^\circ}{\sin32^\circ}\right)-\sqrt3\left(\frac{\cos38^\circ cosec52^\circ}{\tan15^\circ\tan60^\circ\tan75^\circ}\right)=1{/tex}

Draw a line segment of length 7cm . Find a point p on it which divide it in the ratio 3:5

Posted by Susmita Kumari 6 years, 6 months ago

CBSE > Class 10 > Mathematics

1 answers

Sia ? 6 years, 6 months ago

We have to draw a line segment of length 7 cm.Then,we have to find a point P on it, which divides it in the ratio 3 : 5.
Steps of construction:

Draw a line segment {tex}AB=7{/tex} cm.
Draw a ray AX, making an acute {tex}\angle BAX{/tex} with AB.
Mark {tex}3+5=8{/tex} points, i.e, {tex}A_1, A_2, A_3, A_4 ...A_8{/tex} on AX, such that {tex}AA_1 = A_1A_2 = A_2A_3 = A_3A_4 ... = A_7A_8{/tex}
Join A{tex}_8{/tex}B
From A₃, draw {tex}A_3P || A_8B{/tex} which intersects AB at point P [ by making an angle at A₃ equal to {tex}\angle AA_8B{/tex}
Then, P is the point on AB which divides it in the ratio 3:5. So, {tex}AP : PB = 3:5{/tex}

Justification: In {tex}\triangle ABA_8{/tex}, we have {tex}A_3P || A_8B{/tex}
{tex}\therefore \frac{AP}{PB}=\frac{AA_3}{A_3A_8}{/tex} [ by basic proportionality theorem]
By construction, {tex}\frac{AA_3}{A_3A_8}=\frac{3}{5}{/tex}
Hence, {tex}\frac{AP}{PB}=\frac{3}{5}{/tex}

According to the question, {tex}\triangle ABC {/tex} is an equilateral triangle.
In {tex}\triangle{/tex}ABD, using Pythagoras theorem,

{tex}\Rightarrow{/tex} AB² = AD² + BD²
{tex}\Rightarrow{/tex} BC² = AD² + BD², (as AB = BC = CA)
{tex}\Rightarrow{/tex} (2 BD)² = AD² + BD², (perpendicular is the median in an equilateral triangle)
{tex}\Rightarrow{/tex} 4BD² - BD² = AD²
{tex}\therefore{/tex} 3BD² = AD²

Prove 2is rational no.

Posted by Niraj Singh 7 years, 1 month ago

CBSE > Class 10 > Mathematics

1 answers

Kannu Kranti Yadav 7 years, 1 month ago

Let , √2 be a rational number . Then it can be written in the form of a/b where b≠0 and ( a,b are co prime no.s) √2=a/b , now squaring on both sides.. 2= a²/b²... 2b²=a² .. it means a² is divisible by 2 . So a is also divisible by 2. .......... Let , a=2c , now squaring on both sides a²=4 c² putting value of a²... 2b²=4c² --> b²=2c² it means b² is divisible by 2 , so b is also divisible by 2 . Therefore our assumption is wrong . Hence, due to contradiction √2 is an irrational number as it has other common factor other than a and b . Hence, proved that √2 is an irrational number
