X+y+z=1, 2x+3y+2z=2 and ax+ay+2az=4 solve the equation by the method of inversion

Answer»

$\textbf{Given:}$

$<klux>X</klux>+y+z=1,\;2x+<klux>3Y</klux>+2z=2,\;ax+ay+2az=4$

$\textbf{To find:}$

$\text{The values of x,y and z by matrix inversion <klux>METHOD</klux>}$

$\textbf{Solution:}$

$\text{The given system of equations can be written as}$

$\left[\begin{array}{ccc}1&1&1\\2&3&2\\a&a&2a\end{array}\right]\left[\begin{array}{c}x\\y\\z\end{array}\right]=\left[\begin{array}{c}1\\2\\4\end{array}\right]$

$\text{This is of the form}\;AX=B$

$\text{Here}$

$A=\left[\begin{array}{ccc}1&1&1\\2&3&2\\a&a&2a\end{array}\right]$

$|A|=1(6a-2a)-1(4a-2a)+1(2a-3a)$

$|A|=4a-2a-a$

$|A|=a$

$\text{Cofactor matrix of A is}$

$\left[\begin{array}{ccc}4a&-2a&-a\\-a&a&0\\-1&1&0\end{array}\right]$

$\text{Adjoint of matrix A = Transpose of cofactor matrix of A}$

$\text{Then}$

$adj\,A=\left[\begin{array}{ccc}4a&-a&-1\\-2a&a&0\\-a&0&1\end{array}\right]$

$A^{-1}=\frac{1}{|A|}(adjA)$

$A^{-1}=\frac{1}{a}\left[\begin{array}{ccc}4a&-a&-1\\-2a&a&0\\-a&0&1\end{array}\right]$

$\text{Now,}$

$X=A^{-1}B$

$X=\frac{1}{a}\left[\begin{array}{ccc}4a&-a&-1\\-2a&a&0\\-a&0&1\end{array}\right]\left[\begin{array}{c}1\\2\\4\end{array}\right]$

$X=\frac{1}{a}\left[\begin{array}{c}4a-2a-4\\-2a+2a+0\\-a+0+4\end{array}\right]$

$X=\frac{1}{a}\left[\begin{array}{c}2a-4\\0\\4-a\end{array}\right]$

$X=\left[\begin{array}{c}\frac{2a-4}{a}\\0\\\frac{4-a}{a}\end{array}\right]$

$\therefore\textbf{The solution is}$

$\bf\,x=\frac{2a-4}{a}$

$\bf\,y=0$

$\bf\,z=\frac{4-a}{a}$

Find m so that (–2)m + 1 × (–2)3 = (–2)9

Answer»

$(-2)^{m+1} \times (-2)^{3} = (-2)^{9}$

$\implies (-2)^{(m+1+3)} = (-2)^{9}$

$\boxed {\pink { a^{m} \times a^{n} = a^{m+n} }}$

$\implies (-2)^{m+4} = (-2)^{9}$

$\implies m + 4 = 9$

$\boxed {\pink { If \: a^{m} = a^{n} \:then \: m = n }}$

$\implies m = 9 - 4$

$\implies m = 5$

THEREFORE.,

$\red { Value \:of \: m } \green { = 5 }$

Answer» Answer: 306 Step-by-step EXPLANATION: SUPPOSE the number is : A0B According to the question Ax100+ 0x10+ B= 34 (A+0+B) => 100A+ B= 34 A+ 34 B => 100A- 34A = 34B-B => 66A= 33B => 6 A= 3 B Hence A= 3, B =6 the number is 306 Again 603- 306 = 396 PROVED

In a three digit number middle digit is zero. Anumber is 34 times sum of digits. If digits on unitsand hundred place are interchanged then newnumber formed is more by 396 than originalnumber. Find the number (2002)

Answer»

Answer:

306

Step-by-step EXPLANATION:

SUPPOSE the number is : A0B

According to the question

Ax100+ 0x10+ B= 34 (A+0+B)

=> 100A+ B= 34 A+ 34 B

=> 100A- 34A = 34B-B

=> 66A= 33B

=> 6 A= 3 B

Hence A= 3, B =6

the number is 306

Again 603- 306 = 396

Answer» Step-by-step EXPLANATION: For C CP = 9.90 For B SP= 9.90 Loss= 10 per cent CP= SP×100/100-Loss = 9.90×100/100-10 = Rs.11 For A SP=11 Profit= 2.5 percent CP= 11×100/100+2.5 = 13.5 So, A paid 13.5

39.

A sold in article to b at A profit of 2.5 %, B sold the same article to C at a loss of 10%. if C paid 9.90 for it, how much did it cost to A

Answer»

Step-by-step EXPLANATION:

For C

CP = 9.90

For B

SP= 9.90

Loss= 10 per cent

CP= SP×100/100-Loss

= 9.90×100/100-10

= Rs.11

For A

SP=11

Profit= 2.5 percent

CP= 11×100/100+2.5

= 13.5

So, A paid 13.5

Answer» (i) His TOTAL investment is ₹4320. (ii) The rate of return is 12.5% Step-by-step explanation: Nominal VALUE of each share = 100 RS. Dividend on one share = 15% × 100 = 15 Rs. Let the number of purchased SHARES =n Number of shares × dividend per share = annual dividend n × 15 = 540 15n = 540 n = 36 (i) His total investment = Number of shares × Market value of per share Market value of one share = 100 +(20% ×100) = 100 + 20 = 120 Rs. His total investment = 120 × 36 = 4,320 Rs. (ii) Rate of return on his investment = $\frac{income}{investment}\times 100$ = $\frac{540}{4320}\times 100$ = 12.5% The rate of return is 12.5% Learn more dividend and rate of return : brainly.in/question/7948430

A man invests a sum of money in Rs.100 shares, paying 15%dividend, quoted at 20% premium. If his annual dividend isRs.540, calculate :(i) His total investment.(ii) The rate of return on his investment.

Answer»

(i) His TOTAL investment is ₹4320.

(ii) The rate of return is 12.5%

Step-by-step explanation:

Nominal VALUE of each share = 100 RS.

Dividend on one share = 15% × 100

= 15 Rs.

Let the number of purchased SHARES =n

Number of shares × dividend per share = annual dividend

n × 15 = 540

15n = 540

n = 36

(i) His total investment = Number of shares × Market value of per share

Market value of one share = 100 +(20% ×100)

= 100 + 20

= 120 Rs.

His total investment = 120 × 36 = 4,320 Rs.

(ii) Rate of return on his investment = $\frac{income}{investment}\times 100$

= $\frac{540}{4320}\times 100$

= 12.5%

The rate of return is 12.5%
