Kya kabhi parents and children equal ho sakten h . Aaise hi bhagwan aur ham bhi kabhi equal nahi ho sakten. Kyounki ounhone hame banaya h aur ham khud ko banane wale ke kabhi barabar nahi ho sakte kaise bhi. Vo parmatma h aur ham kewal aatma.

Time cannot be destroyed because we are bound to move with time. But time can be wasted by simply sitting without thinking and looking at the clock continuously . And by more sleeping and wasting time in social networking sites.

Life is not a hell if you see clearly it a a very beautiful gift of God. On the other hand if we se other species, animals , birds ,trees etc . They are more unhappy , scared, or malaise then us but they didn't complain for their life just not because they are unable to speak but they know it's value more than human beings. In really, after so many problems they are living and can be called as lived .But mostly all lived humans beings are dead because of their poor and bad works or thinking.

No legendary you're wrong.... the correct formula for finding proper subset is 2ⁿ-1 as Yogita mam has written.... And the formula 2ⁿ you're saying is for finding no. of subsets.... I hope u understand and if u still have any doubt u can ask me....

Yogita Ingle 5 years, 3 months ago

The number of proper subsets of any set is given by the formula 2ⁿ -1 where n is the number of elements in the set.

Here n = 5

2⁵ -1 = 32 - 1 = 31

What is permutation?

Posted by Rithika Mishra 5 years, 3 months ago

CBSE > Class 11 > Mathematics

1 answers

Yogita Ingle 5 years, 3 months ago

A permutation is defined as an arrangement in a definite order of a number of objects taken some or all at a time. Counting permutations are merely counting the number of ways in which some or all objects at a time are rearranged. The convenient expression to denote permutation is defined as “ ⁿP_r”.

The permutation formula is given by,

P_r = n!/(n-r)! ; 0 ≤ r ≤ n

If the lines 2x + y-3=0,5x+Ky-3=0 and 3x-y-2=0 are concurrent , find the value of K

Gaurav Seth 5 years, 3 months ago

We know that, Three lines are said to be concurrent, if they pass through a common point which also means that the point of intersection of any two lines always lies on the third line.

Now, the three given equations of line are:

2x + y − 3 = 0 ... (1)

5x + ky − 3 = 0 ... (2)

and 3x − y − 2 = 0 ... (3)

Firstly, we will solve the equations (1) and (3) and find out the value of x and y. The corresponding value of x and y will also satisfy the equation (2) as all the given lines are concurrent.

Therefore, on adding (1) and (3), we get

2x + y − 3 + 3x − y − 2 = 0

⇒ 5x - 5 = 0

⇒ x = 1

On putting value of x in (1), we get

2(1) + y − 3 =0

⇒ y - 1 = 0

⇒ y = 1

So, the point of intersection of two lines is (1, 1).

Now, this point will also satisfy the equation (2).

Therefore, on putting (x, y) = (1, 1) in (2), we get

5(1) + k(1) − 3 = 0

⇒ k + 2 = 0

⇒ k = - 2

⠀ 5 years, 3 months ago

Let p(k) = n(n+1)(n+2) divisivle by 6
For n = 1 ,
p(k) is true
Let for n = k ,p(k) is true
For n = k+1:
(k+1)(k+2)(k+3)
k(k+1)(k+2)(k+3)/k divisible by 6
So by mathematical induction , statement is true for all n€N
