SOLVE IT:33, 15, 24,52, 117_____,460

Answer»

Correct Qᴜᴇsᴛɪᴏɴ :-

13, 15, 24 , 52 , 117, ____ , 460 ?

Sᴏʟᴜᴛɪᴏɴ :-

we have to COMPLETE the series with suitable Pattern.

Lets Try to See The difference Between Numbers First .

➼ 15 - 13 = 2

➼ 24 - 15 = 9

➼ 52 - 24 = 28

➼ 117 - 52 = 65

➼ X - 117 = ?

➼ 460 - X = ?

Now, when we See Difference We can see Our Logic .

☛ Logic :- Add (Natural NUMBER)³ + 1

So,

➼ 15 - 13 = 2 = 1³ + 1

➼ 24 - 15 = 9 = 2³ + 1

➼ 52 - 24 = 28 = 3³ + 1

➼ 117 - 52 = 65 = 4³ + 1

So, Next Will be 5³ + 1

➼ 117 + (5³+1) = 243 . (ANS.)

Lets Check Now, Next will be (6³ + 1) .

HENCE,

➼ 243 + (6³ + 1)

➼ 243 + 217

➼ 460 (Satisfy).

Therefore , Our Correct Answer will be 243 which Satisfy the given series.

If x=9-4√5, find the value of x² + 1/x²

Answer»

QUESTION :–

▪︎ If ${ \bold{x = 9 - 4 \sqrt{5} }}$ then find the value of ${ \bold{ {x}^{2} + \dfrac{1}{ {x}^{2} } = ? }}$

ANSWER :–

$\\ \longrightarrow{ \red {\boxed{ \bold{ {x}^{2} + \dfrac{1}{ {x}^{2} } = 322 }}}} \\$

EXPLANATION :–

GIVEN :–

$\\ { \implies \: \bold{x = 9 - 4 \sqrt{5} }} \\$

TO FIND :–

$\\ \implies { \bold{ {x}^{2} + \dfrac{1}{ {x}^{2} } = ? }} \\$

SOLUTION :–

• First , we have to find $\: \: \: { \bold{ \dfrac{1}{x} \: \: - }} \\$

$\\ \implies{ \bold{ \dfrac{1}{x} \: \: = \frac{1}{9 - 4 \sqrt{5} } }} \\$

• Now Rationalization –

$\\ \implies{ \bold{ \dfrac{1}{x} \: \: = \frac{1}{9 - 4 \sqrt{5} } \times \frac{9 + 4 \sqrt{5} }{9 + 4 \sqrt{5} } }} \\$

$\\ \implies{ \bold{ \dfrac{1}{x} \: \: = \frac{9 + 4 \sqrt{5} }{(9)^{2} - (4 \sqrt{5}) ^{2} } }} \\$

$\\ \implies{ \bold{ \dfrac{1}{x} \: \: = \frac{9 + 4 \sqrt{5} }{81 - 80 } }} \\$

$\\ \implies{ \bold{ \dfrac{1}{x} \: \: = 9 + 4 \sqrt{5} }} \\$

• We know a property –

$\\ \implies{ \pink{ \boxed{\bold{ {(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab }}}} \\$

• So that –

$\\ \implies{ \bold{ {(x + \frac{1}{x} )}^{2} = {x}^{2} + \dfrac{1}{ {x}^{2} } + 2( \cancel x)( \frac{1}{ \cancel x} ) }} \\$

$\\ \implies{ \bold{ {(x + \frac{1}{x} )}^{2} = {x}^{2} + \dfrac{1}{ {x}^{2} } + 2 }} \\$

• We should write this as –

$\\ \implies{ \bold{ {x}^{2} + \dfrac{1}{ {x}^{2} } = {(x + \frac{1}{x} )}^{2} - 2 }} \\$

• Now PUT the values –

$\\ \implies{ \bold{ {x}^{2} + \dfrac{1}{ {x}^{2} } = {(9 - \cancel{4 \sqrt{5} } +9 + { \cancel{4 \sqrt{5} }} )}^{2} - 2 }} \\$

$\\ \implies{ \bold{ {x}^{2} + \dfrac{1}{ {x}^{2} } = {(18)}^{2} - 2 }} \\$

$\\ \implies{ \bold{ {x}^{2} + \dfrac{1}{ {x}^{2} } = 324 - 2 }} \\$

$\\ \implies{ \boxed{ \bold{ {x}^{2} + \dfrac{1}{ {x}^{2} } = 322 }}} \\$

Find the equation of the straight lines each passing through the point ( 6 , -2 )and whose sum of the intercepts is 5

Answer»

Answer:

GIVEN :–

▪︎ Straight line passing from point (6,-2).

▪︎ Sum of intercepts = 5

TO FIND :–

Equation of straight line .

SOLUTION :–

▪︎ Intercept FORM of line is –

\begin{lgathered}\\ \implies \: { \boxed{ \bold{ \dfrac{x}{a} + \dfrac{y}{b} = 1 }}} \\\end{lgathered}

⟹

a

x

+

b

y

=1

\begin{lgathered}\\ \to \: { \bold{Here \: a \: \: and \: \: b \: \: are \: \: x - intercept \: \: and \: \: y - intercept \: \: respectively.}} \\\end{lgathered}

→Hereaandbarex−interceptandy−interceptrespectively.

▪︎ According to the question line passing from a point (6,-2) , So that –

\begin{lgathered}\\ \implies{ \bold{ \dfrac{6}{a} + \dfrac{( - 2)}{b} = 1 \: \: \: \: - - - - eq.(1)}} \\\end{lgathered}

⟹

a

6

+

b

(−2)

=1−−−−eq.(1)

• And sum of intercepts = 5

\begin{lgathered}\\ \implies{ \bold{ a + b= 5 \: \: \: \: - - - - eq.(2)}} \\\end{lgathered}

⟹a+b=5−−−−eq.(2)

▪︎ Now by eq.(1) and eq.(2) –

\begin{lgathered}\\ \implies{ \bold{ \dfrac{6}{a} + \dfrac{( - 2)}{(5 - a)} = 1 }} \\\end{lgathered}

⟹

a

6

+

(5−a)

(−2)

=1

\begin{lgathered}\\ \implies{ \bold{ \dfrac{6(5 - a) - 2(a)}{a(5 - a)} = 1 }} \\\end{lgathered}

⟹

a(5−a)

6(5−a)−2(a)

=1

\begin{lgathered}\\ \implies{ \bold{ \dfrac{30- 6a- 2a}{a(5 - a)} = 1 }} \\\end{lgathered}

⟹

a(5−a)

30−6a−2a

=1

\begin{lgathered}\\ \implies{ \bold{ \dfrac{30 - 8a}{a(5 - a)} = 1 }} \\\end{lgathered}

⟹

a(5−a)

30−8a

=1

\begin{lgathered}\\ \implies{ \bold{ 30 - 8a = 5a - {a}^{2} }} \\\end{lgathered}

⟹30−8a=5a−a

\begin{lgathered}\\ \implies{ \bold{ {a }^{2} - 13A + 30 = 0 }} \\\end{lgathered}

⟹a

−13a+30=0

\begin{lgathered}\\ \implies{ \bold{ {a }^{2} - 10a - 3a + 30 = 0 }} \\\end{lgathered}

⟹a

−10a−3a+30=0

\begin{lgathered}\\ \implies{ \bold{ a(a - 10) - 3(a - 10 )= 0 }} \\\end{lgathered}

⟹a(a−10)−3(a−10)=0

\begin{lgathered}\\ \implies{ \bold{( a - 3)(a - 10) = 0 }} \\\end{lgathered}

⟹(a−3)(a−10)=0

\begin{lgathered}\\ \implies{ \bold{a = 3 \: , \: a = 10 }} \\\end{lgathered}

⟹a=3,a=10

• Now using eq.(2) –

\begin{lgathered}\\ \implies{ \bold{b = 2 \: , \: b = - 5 }} \\\end{lgathered}

⟹b=2,b=−5

EQUATION :–

(1) When a = 3 , b = 2 :–

\begin{lgathered}\\ \implies \: { \boxed{ \bold{ \dfrac{x}{3} + \dfrac{y}{2} = 1 }}} \\\end{lgathered}

⟹

(2) When a = 10 , b = -5 :–

2 men and 7 boys can do a work in 4 days.the same work is done in 3 days by 4 men and 4 boys.how long would it take for one man and one boy to do it alone??

Answer»

ANSWER:

Step-by-step EXPLANATION: let no. of MEN be =X

let no. of boys=y

first equation-2x+7y=4

second equation=4x+4y=3

$2x+7y=4\\2x=4-7y\\\frac{4-7y}{2} =x$

insert value of x in second equation

$\frac{4-7y}{2} +4y=3\\\frac{4-7y+8y}{2} =3\\\\\frac{4+y}{2} =3\\\frac{4+y}{} =6\\ y=2$

4-7y/2=x

4-14/2=x

10/2=x

5=x

x+y=2+5=7

The product of two number is 205/7. If one of the number is 6⅔find the other

Answer»

Answer:

4 11/28

Step-by-step EXPLANATION:

LET the other no. be X

6 2/3 multiplied by x = 205/7

x = 205/7 ÷ 6 2/3

= 205/7 ÷ 20/3

= (205×3) / (7×20)

= (41×3) / (7×4)

= 123/28
