7.

Find f(x)g (x) = x² + x - 2 and (gof) (x) = 4x² -10x + 4

Answer»

Answer:

2x-3

Step-by-step explanation:

given G(x)=x²+x-2

and gof(x)=4x²-10x+4=>g(F(x))=4x²-10x+4...(1)

g(f(x)) is ALSO equal to f(x)²+f(x)-2...(2)

from 1 and 2 we get

f(x)²+f(x)-2=4x²-10x+4

f(x)²-f(x)+2F(x)-2=4x²-8x-2x+4

f(x)²+f(x)+(1/2)²=4x²-10x+4+2+(1/2)²

(f(x)+1/2)²=4x²-10x+6+1/4

(f(x)+1/2)²=4x²-10x+25/4=(2x-5/2)²

f(x)+1/2=2x-5/2

f(x)=2x-3

17.	(x+y+1)dy/dx=1 differential equation
Answer» ANSWER: $\sf <klux>X</klux>+y=Ce^y-2$ Step-by-step explanation: Given: The differential equation (x + y + 1) dy/dx = 1 To Find: Solution for the given differential equation Solution: $\sf (x + y+1)\dfrac{dy}{dx} =1$ $\sf \dfrac{dy}{dx} =\dfrac{1}{x+y+1}$ $\sf \dfrac{dx}{dy} =x+y+1$ $\sf \dfrac{dx}{dy} -x=y+1$ Now this is in the form of a LINEAR differential equation, $\sf \dfrac{dx}{dy} +Px=Q$ where P = -1 and Q = y + 1 Now finding the INTEGRATING factor (I.F), $\displaystyle \sf I.F=e^{\int\limits {P} \, dy }$ Substitute the data, $\displaystyle \sf I.F=e^{\int\limits {-1} \, dy }$ $\implies \sf e^{-y}$ Now the solution of a linear differential equation is given by, $\displaystyle \sf x\times (I.F)=\int\limits {(Q\times I.F)} \, dy +C$ Substituting it we get, $\displaystyle \sf x\times e^{-y}=\int\limits {(y+1)\times e^{-y}} \, dy$ Now integrating by parts, $\displaystyle \sf x\times e^{-y}=(y+1)\times -e^{-y}-\int\limits {1\times -e^{-y}} \, dy$ $\displaystyle \sf xe^{-y}=-(y+1)\times e^{-y}-e^{-y}+C$ TAKING $\sf e^{-y}$ common, $\sf xe^{-y}=e^{-y}(-y-1-1)+C$ Now dividing by $\sf e^{-y}$ we get, $\sf x=-y-2+Ce^y$ $\sf x+y=Ce^y-2$ This is the solution of the given differential equation.

17.

(x+y+1)dy/dx=1 differential equation

Answer»

ANSWER:

$\sf <klux>X</klux>+y=Ce^y-2$

Step-by-step explanation:

Given:

The differential equation (x + y + 1) dy/dx = 1

To Find:

Solution for the given differential equation

Solution:

$\sf (x + y+1)\dfrac{dy}{dx} =1$

$\sf \dfrac{dy}{dx} =\dfrac{1}{x+y+1}$

$\sf \dfrac{dx}{dy} =x+y+1$

$\sf \dfrac{dx}{dy} -x=y+1$

Now this is in the form of a LINEAR differential equation,

$\sf \dfrac{dx}{dy} +Px=Q$

where P = -1 and Q = y + 1

Now finding the INTEGRATING factor (I.F),

$\displaystyle \sf I.F=e^{\int\limits {P} \, dy }$

Substitute the data,

$\displaystyle \sf I.F=e^{\int\limits {-1} \, dy }$

$\implies \sf e^{-y}$

Now the solution of a linear differential equation is given by,

$\displaystyle \sf x\times (I.F)=\int\limits {(Q\times I.F)} \, dy +C$

Substituting it we get,

$\displaystyle \sf x\times e^{-y}=\int\limits {(y+1)\times e^{-y}} \, dy$

Now integrating by parts,

$\displaystyle \sf x\times e^{-y}=(y+1)\times -e^{-y}-\int\limits {1\times -e^{-y}} \, dy$

$\displaystyle \sf xe^{-y}=-(y+1)\times e^{-y}-e^{-y}+C$

TAKING $\sf e^{-y}$ common,

$\sf xe^{-y}=e^{-y}(-y-1-1)+C$

Now dividing by $\sf e^{-y}$ we get,

$\sf x=-y-2+Ce^y$

$\sf x+y=Ce^y-2$

This is the solution of the given differential equation.

26.	4/x -9/y= -1 and 15x/2 -5y=0. Solve for x and y
Answer» Hope this is helpful for you Step-by-step explanation: Solution: We have, 3X8 = 2X12. So, we write the given equation in the following form: [(x + 2)(x + 12)][(x + 3)(x + 8)] = 4x2 => (x2 + 14x + 24)(x2 + 11x + 24) = 4x2 Dividing throughout by x2, we get (x + 14 + 24/x)(x + 11 + 24/x) = 4 => (y + 14)(y + 11) = 4, where x + 24/x = y => y2 + 25Y + 154 = 4 => y2 + 25y + 150 = 0 => (y + 15)(y + 10) = 0 => y = -15, -10 If y = -15, then x + 24/x = -15 => x2 + 15x + 24 = 0 => x = [-15 ±√129]/2 If y = -10, then x + 24/x = -10 => x2 + 10x + 24 = 0 => (x + 4)(x + 6) = 0 => x = -4,-6. Hence, the ROOTS of the given equation are -4,-6, [-15 ±√129]/2.

26.

4/x -9/y= -1 and 15x/2 -5y=0. Solve for x and y

Answer»

Hope this is helpful for you

Step-by-step explanation:

Solution: We have, 3X8 = 2X12. So, we write the given equation in the following form:

[(x + 2)(x + 12)][(x + 3)(x + 8)] = 4x2

=> (x2 + 14x + 24)(x2 + 11x + 24) = 4x2

Dividing throughout by x2, we get

(x + 14 + 24/x)(x + 11 + 24/x) = 4

=> (y + 14)(y + 11) = 4, where x + 24/x = y

=> y2 + 25Y + 154 = 4

=> y2 + 25y + 150 = 0

=> (y + 15)(y + 10) = 0

=> y = -15, -10

If y = -15, then

x + 24/x = -15

=> x2 + 15x + 24 = 0

=> x = [-15 ±√129]/2

If y = -10, then x + 24/x = -10

=> x2 + 10x + 24 = 0

=> (x + 4)(x + 6) = 0

=> x = -4,-6.

Hence, the ROOTS of the given equation are -4,-6, [-15 ±√129]/2.

40.

A-1/a=3, find a^3-1/a^3

Answer»

Answer:

36

Step-by-step EXPLANATION:

(a - 1/a)^3 = a^3-1/a^3 -3 a×1/a(a-1/a)

(3)^3 =a^3-1/a^3-3(3)

27 = a^3-1/a^3-9

X^3 + 1/x^3 = ? What is the answer

Answer»

QUESTION :–

• If $\: \: { \bold{x + \dfrac{1}{x} = \sqrt{3} }} \: \:$ , then find $\: \: { \bold{x {}^{3} + \dfrac{1}{x {}^{3} } = ? }} \: \:$

ANSWER :–

GIVEN :–

$\\ \: \: { \huge{.}} \: \: { \bold{x + \dfrac{1}{x} = \sqrt{3} }} \: \: \\$

TO FIND :–

$\: \: { \huge{.}} \: \: { \bold{x {}^{3} + \dfrac{1}{x {}^{3} } = ? }} \: \:$

SOLUTION :–

$\\ \: \implies \: { \bold{x + \dfrac{1}{x} = \sqrt{3} }} \: \: \\$

• TAKE cube on both side –

$\\ \: \implies \: { (\bold{x + \dfrac{1}{x} ) {}^{3} = (\sqrt{3} ) {}^{3} }} \: \: \\$

• Using IDENTITY –

$\\ \: \longrightarrow \: \large { \boxed{ (\bold{a+ b) {}^{3} = { a }^{3} + {b}^{3} + 3ab(a + b)}}} \: \: \\$

• So that –

$\\ \: \implies \: { \bold{(x ) {}^{3} + (\dfrac{1}{x}) {}^{3} + 3(x)( \dfrac{1}{x} ) [x + \dfrac{1}{x} ] = ( \sqrt{3} ) {}^{3} }} \\$

$\\ \: \implies \: { \bold{(x ) {}^{3} + (\dfrac{1}{x}) {}^{3} + 3(x + \dfrac{1}{x})= 3 \sqrt{3} }} \\$

$\\ \: \implies \: { \bold{(x ) {}^{3} + (\dfrac{1}{x}) {}^{3} + 3( \sqrt{3} )= 3 \sqrt{3} }} \\$

$\\ \: \implies \: { \bold{x {}^{3} + \dfrac{1}{x {}^{3} }= 3 \sqrt{3} - 3 \sqrt{3} }} \\$

$\\ \: \implies \large{ \boxed { \bold{x {}^{3} + \dfrac{1}{x {}^{3} }= 0 }}} \\$

• HENCE , $\: \: \: { { \bold{x {}^{3} + \dfrac{1}{x {}^{3} }= 0 }}}$

46.	Determine the values of and b for which the following pairs of linear equations has infinitely many solutions3x-(a+1)y=2b-15x+1(1-2a)y=3b
Answer» Answer: Hope it helps MRK ME AS BRAINLIEST Step-by-step explanation: Given PAIR of linear equations: 3x-(a+1)y=2b-1......................1 5x+(1-2a)y=3B......................2 Here we have, a1=3 , a2=5 , b1=-a-1 , b2=1-2a , c1=2b-1 , c2=3b The condition required for which pair of linear equation has INFINITELY many SOLUTION is, a1/a2 = b1/b2 = c1/c2 By putting all values we have, 3/5 = (-a-1)/(1-2a) = (2b-1)/(3b) 3/5 = (-a-1)/(1-2a) and 3/5 = (2b-1)/(3b) 3-6a = -5a-5 and 9b =10b-5 a = 8 and b=5 For value of a=8 and b=5 ,the given pair of linear equation has infinitely many solutions.

Determine the values of and b for which the following pairs of linear equations has infinitely many solutions3x-(a+1)y=2b-15x+1(1-2a)y=3b

Answer»

Answer:

Hope it helps MRK ME AS BRAINLIEST

Step-by-step explanation:

Given PAIR of linear equations:

3x-(a+1)y=2b-1......................1

5x+(1-2a)y=3B......................2

Here we have,

a1=3 , a2=5 , b1=-a-1 , b2=1-2a , c1=2b-1 , c2=3b

The condition required for which pair of linear equation has INFINITELY many SOLUTION is,

a1/a2 = b1/b2 = c1/c2

By putting all values we have,

3/5 = (-a-1)/(1-2a) = (2b-1)/(3b)

3/5 = (-a-1)/(1-2a) and 3/5 = (2b-1)/(3b)

3-6a = -5a-5 and 9b =10b-5

a = 8 and b=5

For value of a=8 and b=5 ,the given pair of linear equation has infinitely many solutions.
