What is the solution ofthe given matrixequation?[3 15 2]X =[-1 23 1]

Answer»

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

Given that,

$\rm :\longmapsto\:\: \begin{bmatrix} 3 & <klux>1</klux>\\ 5 & <klux>2</klux>\end{bmatrix}X = \: \begin{bmatrix} - 1 & 2\\ 3 & 1\end{bmatrix} - - (1)$

Let assume that,

$\rm :\longmapsto\:A = \begin{bmatrix} 3 & 1\\ 5 & 2\end{bmatrix}$

and

$\rm :\longmapsto\:B = \: \begin{bmatrix} - 1 & 2\\ 3 & 1\end{bmatrix}$

So, equation (1) can be rewritten as

$\rm :\longmapsto\:AX = B$

$\red{ \bf \: Pre - multiply \: by \: {A}^{ - 1} \: on \: both \: sides}$

$\rm :\longmapsto\: {A}^{ - 1} AX = {A}^{ - 1} B$

$\rm :\longmapsto\: X = {A}^{ - 1} B - - (2)$

Now,

As

$\rm :\longmapsto\:A = \begin{bmatrix} 3 & 1\\ 5 & 2\end{bmatrix}$

$\rm :\longmapsto\: |A| = 6 - 5 = 1$

$\rm :\longmapsto\:adjA = \begin{bmatrix} 2 & - 1\\ - 5 & 3\end{bmatrix}$

We know,

$\rm :\longmapsto\: {A}^{ - 1} = \dfrac{1}{ |A| } adjA$

Hence,

$\rm :\longmapsto\: {A}^{ - 1} = \dfrac{1}{1} \begin{bmatrix} 2 & - 1\\ - 5 & 3\end{bmatrix}$

$\bf\implies \: {A}^{ - 1} = \begin{bmatrix} 2 & - 1\\ - 5 & 3\end{bmatrix} - - - (3)$

Now SUBSTITUTING all the VALUES in equation (2), we get

$\rm :\longmapsto\:X = \begin{bmatrix} 2 & - 1\\ - 5 & 3\end{bmatrix}\: \begin{bmatrix} - 1 & 2\\ 3 & 1\end{bmatrix}$

$\rm :\longmapsto\:X = \begin{bmatrix} - 2 - 3 & 4- 1\\ 5 + 9 & - 10 + 3\end{bmatrix}\:$

$\bf :\longmapsto\:X = \begin{bmatrix} -5 & 3\\ 14 & - 7\end{bmatrix}\:$

Additional INFORMATION :-

$\boxed{ \sf \: {AA}^{ - 1} = {A}^{ - 1}A =I}$

$\boxed{ \sf \: A \: (adjA) = (adjA) \: A = |A|I}$

$\boxed{ \sf \: |adjA| = { |A| }^{n - 1}}$

$\boxed{ \sf \: |AB| = |A| |B| }$

23306.

P(x)=x square+x-1 find the zeroes of the polynomial

Answer»

Solution:

Given,

→ x² + X - 1 = 0

We have to find out the ZEROS of the given equation.

Comparing with ax² + bx + c = 0, we get,

→ a = 1, B = 1, c = -1

So,

→ Discriminant (D) = b² - 4ac

→ D = 1² - 4 × 1 × (-1)

→ D = 1 + 4

→ D = 5

So,

→ x = (-b ± √D)/2a

→ x = (-1 ± √5)/2

Therefore,

→ x = (-1 + √5)/2 and (-1 -√5)/2

Answer:

x = (-1 + √5)/2 and (-1 -√5)/2

At what speed does the second train Y travel if the first train travels at 80 km/h.YAAH WE ARE FRIENDS BUDDY ❤friendship is a single soul develop in two bodies ☺☺✌
Answer» Let speed of Train B = x 120/x= √(9/16) => x = 4 x 120/3 = 160 km/hr Note : This can be solved WITHOUT USING this formula by using fundamentals of TIME, Speed & Distance. Derivation of formula : Let x be the total distance and t be the time at which the two trains meet. Let s1, s2 are speeds of train A, train B respectively and a & b are the times at which they REACH the destination after they meet. x = t(s1 + s2) ...(1) x = (t + a)s1 ...(2) x = (t + b)s2 ...(3) Solving (1), (2) & (3) t = √(a*b) => Time to meet is the Geometric Mean of individual time after meeting. => s1/s2 = √(b/a)

Two trains X and Y start at the same time in the opposite direction from two points P and Q and arrive at their destinations 36 and 25 hours respectively after their meeting each other. At what speed does the second train Y travel if the first train travels at 80 km/h.YAAH WE ARE FRIENDS BUDDY ❤friendship is a single soul develop in two bodies ☺☺✌

Answer»

Let speed of Train B = x

120/x= √(9/16)

=> x = 4 x 120/3 = 160 km/hr

Note : This can be solved WITHOUT USING this formula by using fundamentals of TIME, Speed & Distance.

Derivation of formula :

Let x be the total distance and t be the time at which the two trains meet.

Let s1, s2 are speeds of train A, train B respectively and a & b are the times at which they REACH the destination after they meet.

x = t(s1 + s2) ...(1)

x = (t + a)s1 ...(2)

x = (t + b)s2 ...(3)

Solving (1), (2) & (3)

t = √(a*b)

=> Time to meet is the Geometric Mean of individual time after meeting.

=> s1/s2 = √(b/a)

P(x)=x²+x-1 find the zeroes of the polynomial

Answer»

Step-by-step explanation:

Given a and ẞ are zeroes of the polynomial F(x) = ax2 + BX + c

a+ B = -b/a

aß = c/a.

If a and ẞ are zeroes of the QUADRATIC polynomial p(x)=x2-(k-6)x+(2k+1) and a+B= aßa+ B = k - 6 and aß = 2k + 1

Given that a + B = aß

k-6=2k +1

23337.	Solve the pair of linear equation x/6+y/15=4 & x/3-y/12=19/4
Answer» Step-by-step explanation: X/6 + y/15 =4. x/3 - y/12 =19/4. Multiply EQUATION (x/6 + y/15 = 4) by 30 both Left HAND side and right hand side. Now if you multiply Left hand side by 30 we get 30(x/6 + y/15) = 30x/6 + 30y/15 =5x + 2Y. Now if we multiply Right hand side of the equation by 30 we get 430 = 120. Now if we multiply Left hand side of the equation x/3 - y/12 =19/4 by 12 we get 12(x/3-y/12) =12x/3-12y/12 =4x-y. Now if we multiply Right hand side of the equation by 12 we get 12(19/4) =319 =57. Now we got two new equations 5x+2y =120 and 4x-y = 57 Now multiply the equation 4x-y = 57 by 2 Both Left hand side and Right hand side we get 2(4x-y) = 257. We get 8x-2y = 114. Now if we ADD 5x + 2y = 120 and 8x-2y = 114 both Left hand side and Right hand side we get 5x+2y+8x-2y = 120 + 114 13x =234 So x = 234/13 = 18. So if we substitute x= 18 in 5x+2y = 120 We get 518 +2y = 120 90 + 2y = 120 2y= 120-90 2y = 30 y = 15. So x= 18 and y = 15. Hope you understood.

Solve the pair of linear equation x/6+y/15=4 & x/3-y/12=19/4

Answer»

Step-by-step explanation:

X/6 + y/15 =4.

x/3 - y/12 =19/4.

Multiply EQUATION (x/6 + y/15 = 4) by 30 both Left HAND side and right hand side.

Now if you multiply Left hand side by 30 we get

30*(x/6 + y/15)

= 30*x/6 + 30*y/15

=5x + 2Y.

Now if we multiply Right hand side of the equation by 30 we get

4*30 = 120.

Now if we multiply Left hand side of the equation x/3 - y/12 =19/4 by 12 we get

12*(x/3-y/12)

=12*x/3-12*y/12

=4x-y.

Now if we multiply Right hand side of the equation by 12 we get

12*(19/4)

=3*19

=57.

Now we got two new equations 5x+2y =120 and 4x-y = 57

Now multiply the equation 4x-y = 57 by 2 Both Left hand side and Right hand side we get 2*(4x-y) = 2*57.

We get 8x-2y = 114.

Now if we ADD 5x + 2y = 120 and 8x-2y = 114 both Left hand side and Right hand side we get

5x+2y+8x-2y = 120 + 114

13x =234

So x = 234/13 = 18.

So if we substitute x= 18 in 5x+2y = 120

We get

5*18 +2y = 120

90 + 2y = 120

2y= 120-90

2y = 30

y = 15.

So x= 18 and y = 15.

Hope you understood.

To prove that :---- - cos theta + sin theta +1 / cos theta + sin theya -1 = sec theta + tan theta

Answer»

Answer:

Step-by-step explanation:

CORRECT QUESTION :-

$\dfrac{cos\theta+sin\theta+1}{cos\theta-sin\theta+1}=sec\theta+tan\theta$

Solution :-

Taking L.H.S :-

$= \dfrac{cos\theta+sin\theta+1}{cos\theta-sin\theta+1}$

Dividing Numerator and Denominator with "costheta"

$=\dfrac{\dfrac{cos\theta+sin\theta+1}{cos\theta}}{\dfrac{cos\theta-sin\theta+1}{cos\theta}}$

We KNOW that :-

1) sinA/cosA = tanA

2) 1/cosA = secA

$= \dfrac{1+tan\theta+sec\theta}{1-tan\theta+sec\theta}$

We know that :-

$1) sec^2A-tan^2A = 1$

$\implies \dfrac{sec^2\theta-tan^2\theta+tan\theta+sec\theta}{1-tan\theta+sec\theta}$

$\dfrac{((sec\theta+tan\theta)\times(sec\theta-tan\theta))+(sec\theta+tan\theta)}{1-tan\theta+sec\theta}$

$= \dfrac{sec\theta+tan\theta(sec\theta-tan\theta+1)}{1+tan\theta-sec\theta}$

$= sec\theta+tan\theta$
