Answer» GIVEN:- $\rm{x-\dfrac{1}{x}=4}$ TO FIND:- $\rm{x^2+\dfrac{1}{x^2}}$ IDENTITY USED:- $\rm{(a-b)^2=a^2-2ab+b^2}$ Now, $\implies\rm{x-\dfrac{1}{x}=4}$ Squaring the both SIDES. $\implies\rm{(x-\dfrac{1}{x})^2=(4)^2}$ $\implies\sf{x^2+\dfrac{1}{x^2}-2\times{\cancel{x}}}\times{\dfrac{1}{\cancel{x}}}=16}$ $\implies\rm{x^2+\dfrac{1}{x^2}-2=16}$ $\implies\rm{x^2+\dfrac{1}{x^2}=18}$ .

19.

If x-1/x=4,then find the value of x2+1/x2

Answer»

GIVEN:-

$\rm{x-\dfrac{1}{x}=4}$

TO FIND:-

$\rm{x^2+\dfrac{1}{x^2}}$

IDENTITY USED:-

$\rm{(a-b)^2=a^2-2ab+b^2}$

Now,

$\implies\rm{x-\dfrac{1}{x}=4}$

Squaring the both SIDES.

$\implies\rm{(x-\dfrac{1}{x})^2=(4)^2}$

$\implies\sf{x^2+\dfrac{1}{x^2}-2\times{\cancel{x}}}\times{\dfrac{1}{\cancel{x}}}=16}$

$\implies\rm{x^2+\dfrac{1}{x^2}-2=16}$

$\implies\rm{x^2+\dfrac{1}{x^2}=18}$ .

HENCE, The value of $\rm{x^2+\dfrac{1}{x^2}}$ is 18.

SOME MORE IDENTITY.

$\rm{(a+b)^2=a^2+2ab+b^2}$

$\rm{a^3+b^3=(a+b)(a^2-ab+b^2)}$

$\rm{a^3-b^3=(a-b)(a^2+ab+b^2)}$

Answer» Answer: Fundamental Principle of Addition Step-by-step explanation: "If there are two jobs such that they can be performed independently in ‘m’ and ‘n’ ways RESPECTIVELY, then either of the two jobs can be performed in (m + n) ways." Example :- In her class of 10 girls and 8 boys, the teacher has to select either a girl OR a boy. In how many ways can she make her SELECTION? Here the teacher has to CHOOSE either a girl OR a boy (Only 1 student) For selecting a boy she has 8 options/ways OR that for a girl 10 options/ways. The first of these can be performed in 8 ways and the SECOND in 10 ways. Therefore, by fundamental principle of addition either of the two jobs can be performed in (8 + 10) ways. Hence the teacher can make the selection of a student in 18 ways.

in muli storey building,1/8 of the 728 residents watch the discovery channel ,3/4 watch national geographic and the rest watch cartoon network.what fraction of the total number of residents watch cartoon network

Answer»

Answer:

1/8

Step-by-step explanation:

TOTAL NUMBER of residents = 728

Find the number of residents that watched DISCOVERY channel:

Number of residents = 1/8 x 728

Number of residents = 91

Find the number of residents that watched national GEOGRAPHIC:

Number of residents = 3/4 x 728

Number of residents = 546

Find the number of residents that watched cartoon network:

Number of residents = 728 - 91 - 546

Number of residents = 91

Find the fraction of residents that watched cartoon network:

Fraction = 91/728 = 1/8

Question :A fraction becomes 9/11, if 2 is added to both the numerator & denominator. If 3 is added to both the numerator & denominator it becomes 5/6. Find the fraction.

Answer»

$\large{\underline{\underline{\tt{\red{Answer-}}}}}$

$\large{\boxed{\rm{\blue{Fraction\:=\:\dfrac{7}{9}}}}}$

$\large{\underline{\underline{\tt{\red{Explanation-}}}}}$

Let the numerator and denominator be X and y respectively.

$\rightarrow$ Fraction = $\tt{\dfrac{x}{y}}$

$\bold{\pink{\rm{According\:to\:the\:question-}}}$

If 2 is added to both the numerator & denominator, the fraction BECOMES $\tt{\dfrac{9}{11}}$

$\therefore$ $\tt{\dfrac{x+2}{y+2}\:=\:\dfrac{9}{11}}$

$\rightarrow$ $\tt{11(x+2)\:=\:9(y+2)}$

$\rightarrow$ 11x + 22 = 9y + 18

$\rightarrow$ 11x + 22 - 9y - 18 = 0

$\rightarrow$ 11x - 9y = -4

$\rightarrow$ x = $\tt{\dfrac{9y-4}{11}}$ __________(1)

$\rule{200}2$

If 3 is added to both the numerator & denominator it becomes 5/6.

$\therefore$ $\tt{\dfrac{x+3}{y+3}\:=\:\dfrac{5}{6}}$

$\rightarrow$ 6x + 18 = 5y + 15

Putting the value of x,

$\rightarrow$ 54 - 24 = 55y - 33

$\rightarrow$ $\tt{\cancel{-}\:y\:=\:\cancel{-}\:9}$

$\large{\boxed{\tt{\pink{y\:=\:9}}}}$

★ Now, put the value of y in (1),

$\rightarrow$ x = $\tt{\dfrac{81-4}{11}}$

$\rightarrow$ x = $\tt{\cancel{\dfrac{77}{11}}}$
