22.	Find x,0
Answer» CORRECT STATEMENT is Find x, $\sf \: If \: A = \begin{bmatrix} cosx & - sinx\\ sinx & cosx\end{bmatrix}, \: 0 < x < \dfrac{\pi}{2} \: when \: A + A' = I$ $\large\underline{\sf{Solution-}}$ Given that $\rm :\longmapsto\:A = \begin{bmatrix} cosx & - sinx\\ sinx & cosx\end{bmatrix}$ So, $\rm :\longmapsto\:A' = \begin{bmatrix} cosx & sinx\\ - sinx & cosx\end{bmatrix}$ Now, ACCORDING to statement, $\rm :\longmapsto\:A + A' = I$ $\rm :\longmapsto\:\begin{bmatrix} cosx & - sinx\\ sinx & cosx\end{bmatrix} + \begin{bmatrix} cosx & sinx\\ - sinx & cosx\end{bmatrix} = \begin{bmatrix} 1 & 0\\ 0 & 1\end{bmatrix}$ $\rm :\longmapsto\:\begin{bmatrix} 2cosx & 0\\ 0 & 2cosx\end{bmatrix} = \begin{bmatrix} 1 & 0\\ 0 & 1\end{bmatrix}$ On comparing, we get $\rm :\longmapsto\:2cosx = 1$ $\rm :\longmapsto\:cosx = \dfrac{1}{2}$ $\rm :\longmapsto\:cosx = cos60 \degree$ $\bf\implies \:x = 60 \degree \:$ Additional Information :- For any two matrices A and B, $\boxed{ \bf \: {(A + B)}^{'} = A' + B' }$ $\boxed{ \bf \: {(A - B)}^{'} = A' - B' }$ $\boxed{ \bf \: {(kA)}^{'} = k \: A' } \: \sf \: where \: k \in \: R$ $\boxed{ \bf \: {(A' )}^{'} = A}$ $\boxed{ \bf \: {(AB)}^{'} = B' A' }$

22.

Find x,0

Answer» CORRECT STATEMENT is

Find x,

$\sf \: If \: A = \begin{bmatrix} cosx & - sinx\\ sinx & cosx\end{bmatrix}, \: 0 < x < \dfrac{\pi}{2} \: when \: A + A' = I$

$\large\underline{\sf{Solution-}}$

Given that

$\rm :\longmapsto\:A = \begin{bmatrix} cosx & - sinx\\ sinx & cosx\end{bmatrix}$

So,

$\rm :\longmapsto\:A' = \begin{bmatrix} cosx & sinx\\ - sinx & cosx\end{bmatrix}$

Now,

ACCORDING to statement,

$\rm :\longmapsto\:A + A' = I$

$\rm :\longmapsto\:\begin{bmatrix} cosx & - sinx\\ sinx & cosx\end{bmatrix} + \begin{bmatrix} cosx & sinx\\ - sinx & cosx\end{bmatrix} = \begin{bmatrix} 1 & 0\\ 0 & 1\end{bmatrix}$

$\rm :\longmapsto\:\begin{bmatrix} 2cosx & 0\\ 0 & 2cosx\end{bmatrix} = \begin{bmatrix} 1 & 0\\ 0 & 1\end{bmatrix}$

On comparing, we get

$\rm :\longmapsto\:2cosx = 1$

$\rm :\longmapsto\:cosx = \dfrac{1}{2}$

$\rm :\longmapsto\:cosx = cos60 \degree$

$\bf\implies \:x = 60 \degree \:$

Additional Information :-

For any two matrices A and B,

$\boxed{ \bf \: {(A + B)}^{'} = A' + B' }$

$\boxed{ \bf \: {(A - B)}^{'} = A' - B' }$

$\boxed{ \bf \: {(kA)}^{'} = k \: A' } \: \sf \: where \: k \in \: R$

$\boxed{ \bf \: {(A' )}^{'} = A}$

$\boxed{ \bf \: {(AB)}^{'} = B' A' }$

Total there is 40 litres of milk in starting . So, he will drink 40 litre of mixture on 40th day so, all the milk was empty on 40th day. We have to calculate the amount of water he added in these 40 days because he drank all the water thay he added in 40 days. So, on 1st day, he added 1 litre of water after drinking 1 litre of milk, similarly 2 litre on second day... On 39TH day he will add 39 litres of water in container,and on 40th day all the mixture was empty and he will not add anything. So Formula of ADDING N natural numbers : \begin{gathered} \\ \bf \: = \frac{n \times (n + 1)}{2} \end{gathered} = 2 n×(n+1) (equation 1) In this case value of n = 39 so putting value of n = 39, in equation 1, we get Total quantity of water added : \bf = \frac{39 \times 40}{2} = 39 \times 20 = 780= 2 39×40 =39×20=780 So, He added total 780 litres of water till all the milk is empty.

Answer»

ong>Answer:

780

Step-by-step explanation:

one LITRE of milk on first day , then he add up one litre of water in it and then on second day he drink 2 litres of that mixture,he drinks 3 litre of mixture on third day and it goes on.

Total there is 40 litres of milk in starting .

So, he will drink 40 litre of mixture on 40th day so, all the milk was empty on 40th day.

We have to calculate the amount of water he added in these 40 days because he drank all the water thay he added in 40 days.

So, on 1st day, he added 1 litre of water after drinking 1 litre of milk, similarly 2 litre on second day...

On 39TH day he will add 39 litres of water in container,and on 40th day all the mixture was empty and he will not add anything.

So

Formula of ADDING N natural numbers :

\begin{gathered} \\ \bf \: = \frac{n \times (n + 1)}{2} \end{gathered}

=

2

n×(n+1)

(equation 1)

In this case value of n = 39

so putting value of n = 39, in equation 1, we get

Total quantity of water added :

\bf = \frac{39 \times 40}{2} = 39 \times 20 = 780=

2

39×40

=39×20=780

So,

He added total 780 litres of water till all the milk is empty.

Hi find the equation of locus of point equidistant from the points (1,3) (5,7)

Answer»

<P> $\textbf{Given:}$

$\textsf{Points are (1,3) and (5,7)}$

$\textbf{To <klux>FIND</klux>:}$

$\textsf{The locus of a point which is equidistant from the}$

$\textsf{given two points}$

$\textbf{Solution:}$

$\textsf{Let the given points be A(1,3) and B(5,7)}$

$\textsf{Let P(h,k) be the moving point}$

$\textsf{As per given data,}$

$\mathsf{PA=PB}$

$\mathsf{\sqrt{(h-1)^2+(k-3)^2}=\sqrt{(h-5)^2+(k-7)^2}}$

$\textsf{Squaring on bothsides, we get}$

$\mathsf{(h-1)^2+(k-3)^2=(h-5)^2+(k-7)^2}$

$\mathsf{h^2+1-2h+k^2+9-6k=h^2+25-10h+k^2+49-14k}$

$\mathsf{10-2h-6k=74-10h-14k}$

$\mathsf{8h+8k-64=0}$

$\mathsf{h+k-8=0}$

$\therefore\mathsf{The\;locus\;of\;P\;is}$

$\boxed{\mathsf{x+y-8=0}}$

$\textbf{Find more:}$

Answer» ong>ANSWER: Proof: Let x be an arbitrary odd number. By definition, an odd number is an integer that can be written in the form 2K + 1, for some integer k. This means we can write x = 2k + 1, where k is some integer. ... Since this logic WORKS for any odd number x, we have shown that the square of any odd number is odd.
