Find n such that P(n,5) = 42 P( n,3), n>4

Answer»

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

$\rm :\longmapsto\:P(n,5) = 42P(n,3)$

$\large\underline{\sf{To\:Find - }}$

The VALUE of n

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

Given that

$\rm :\longmapsto\:P(n,5) = 42P(n,3)$

We KNOW,

$\boxed{ \rm{ P(n,r) = \frac{n!}{(n - r)!} \: where \: n \geqslant r}}$

Using this, we GET

$\rm :\longmapsto\:\dfrac{n!}{(n - 5)!} = 42 \times \dfrac{n!}{(n - 3)!}$

$\rm :\longmapsto\:\dfrac{1}{(n - 5)!} = 42 \times \dfrac{1}{(n - 3)(n - 4)(n - 5)!}$

$\rm :\longmapsto\:1 = 42 \times \dfrac{1}{(n - 3)(n - 4)}$

$\rm :\longmapsto\:(n - 3)(n - 4) = 42$

$\rm :\longmapsto\:(n - 3)(n - 4) = 7 \times 6$

On comparing, we get

$\rm :\longmapsto\:n - 3 = 7$

$\bf\implies \:n = 10$

Verification :-

CONSIDER,

$\rm :\longmapsto\:P(n,5)$

$\rm \: = \: \: P(10,5)$

$\rm \: = \: \: \dfrac{10!}{(10 - 5)!}$

$\rm \: = \: \: \dfrac{10!}{5!}$

Now, Consider,

$\rm :\longmapsto\:42 \: P(n,3)$

$\rm \: = \: \: 42 \: P(10,3)$

$\rm \: = \: \: 42 \times \dfrac{10!}{(10 - 3)!}$

$\rm \: = \: \: 42 \times \dfrac{10!}{7!}$

$\rm \: = \: \: 42 \times \dfrac{10!}{7 \times 6 \times 5!}$

$\rm \: = \: \: \dfrac{10!}{5!}$

Hence,

$\rm :\longmapsto\:P(n,5) = 42P(n,3)$

Hence, Verified

2475.

Factorise the following 2x^2+7x+3 by sum and product

Answer»

ANSWER:

X = 3 OR x = $\frac{1}{2}$

Step-by-step EXPLANATION:

The EQUATION : $2x^{2} - 7x + 3$

SUM : -7

Product : 6

It can be split as -1 and -6.

$2x^{2} - x - 6x + 3$ = 0

x(2x - 1) - 3(2x - 1) = 0

(2x - 1)(x - 3) = 0

∴ x - 3 = 0 OR 2x - 1 = 0

x = 3 OR 2x = 1

∴x = 3 OR x = $\frac{1}{2}$

Answer» Step-by-step explanation: Factorization of the expression 1-2 a B-\left(a^{2}+b^{2}\right)1−2ab−(a 2 +b 2 ) is \BOLD{(1+a+b) (1-a-b)}(1+a+b)(1−a−b) Given: 1-2 a b-\left(a^{2}+b^{2}\right)1−2ab−(a 2 +b 2 ) To Find: Factorization of 1-2 a b-\left(a^{2}+b^{2}\right)1−2ab−(a 2 +b 2 ) Solution: The given expression is, 1-2 a b-\left(a^{2}+b^{2}\right)1−2ab−(a 2 +b 2 ) Now, the above expression can be written as 1-\left(a^{2}+b^{2}+2 a b\right)1−(a 2 +b 2 +2ab) The above expression can be written as, =1-(a+b)^{2}\left[\because(a+b)^{2}=a^{2}+b^{2}+2 a b\right]=1−(a+b) 2 [∵(a+b) 2 =a 2 +b 2 +2ab] Now, we get =(1)^{2}-(a+b)^{2}\left[\text { Since, } 1=1^{2}\right]=(1) 2 −(a+b) 2 [ Since, 1=1 2 ] Now, on EXPANDING the above EQUATION, the new expression is, =[1+(a+b)][1-(a+b)]=[1+(a+b)][1−(a+b)] Now, the equation becomes, =(1+a+b)(1-a-b)=(1+a+b)(1−a−b)

Answer»

Step-by-step explanation:

Factorization of the expression 1-2 a B-\left(a^{2}+b^{2}\right)1−2ab−(a

2

+b

2

) is

\BOLD{(1+a+b) (1-a-b)}(1+a+b)(1−a−b)

Given:

1-2 a b-\left(a^{2}+b^{2}\right)1−2ab−(a

2

+b

2

)

To Find:

Factorization of 1-2 a b-\left(a^{2}+b^{2}\right)1−2ab−(a

2

+b

2

)

Solution:

The given expression is,

1-2 a b-\left(a^{2}+b^{2}\right)1−2ab−(a

2

+b

2

)

Now, the above expression can be written as

1-\left(a^{2}+b^{2}+2 a b\right)1−(a

2

+b

2

+2ab)

The above expression can be written as,

=1-(a+b)^{2}\left[\because(a+b)^{2}=a^{2}+b^{2}+2 a b\right]=1−(a+b)

2

[∵(a+b)

2

=a

2

+b

2

+2ab]

Now, we get

=(1)^{2}-(a+b)^{2}\left[\text { Since, } 1=1^{2}\right]=(1)

2

−(a+b)

2

[ Since, 1=1

2

]

Now, on EXPANDING the above EQUATION, the new expression is,

=[1+(a+b)][1-(a+b)]=[1+(a+b)][1−(a+b)]

Now, the equation becomes,

=(1+a+b)(1-a-b)=(1+a+b)(1−a−b)

2497.

Find the eighth term of the geometric sequence which the third term is 36 and the fifth term is 81 .

Answer»

Answer:

The nth term of a GEOMETRIC sequence is given by

an = am×rn−m where:r = COMMON ratio

USE the formula above to SOLVE for r .

an = am×rn−m

a5 = a3×r5–3

a5 = a3×r2

81 = 36×r2

2.25 = r2

r = 1.5

Use again the formula to solve for the 8th term.

an = am×rn−m

a8 = a5×r8–5

a8 = 81×1.53

a8 = 81×1.53 = 273.375

Answer»

Answer:

=>7y+21-2x-4=14

=>7y+17-2x=14

=>7y-2x=14-17

=>7y-2x=-3 ------1st equation

4(y-2)+3(x-3)=2

=>4y-8+3x-9=2

=>4y+3x-17=2

=>4y+3x=2+17

=>4y+3x=19 ------2nd equation

3[7y-2x=-3]

2[4y+3x=19]

21y-6x=-9 -------3rd equation

8y+6x=38 -------4th equation

by elimination

adding EQATION 3 and 4

we get 29y=29

=>y=1

put 'y' is equal to 1 in equation 3

7-2x=-3

-2x=-10
