A/C to question,
9 + 12 + 15 + ....... n terms = 306
you can see that ,
common difference of the series is always equal to 3 . e.g (12 - 9) = (15 - 12) = 3
so, this series is in AP .

now,
Let total number of terms = n in such a way that sum of n terms = 306.

we know,

here, a = 9 , d = 3 and Sn = 306
now,

See this definition in ur maths ncert book u will find all definition with examples ??

power set is the set with all possible subsets denoted by p(a) where a is any other set.
universal set is the set which contain all subsets of other sets and it is denoted by U.
A subset is a set which contain elements of other set.
nullset or empty set does not contain any element
(i)A={x:x is the multiple of 0 <x>18}

Gaurav Seth 4 years, 5 months ago

Any Set that does not contain any element is called the empty or null or void set. The symbol used to represent an empty set is – {} or φ. Examples:

  • Let A = {x : 9 < x < 10, x is a natural number} will be a null set because there is NO natural number between numbers 9 and 10. Therefore, A = {} or φ
  • Let W = {d: d > 8, d is the number of days in a week} will also be a void set because there are only 7 days in a week.

Gaurav Seth 4 years, 5 months ago

A universal set is a set which contains all the elements or objects of other sets, including its own elements. It is usually denoted by the symbol ‘U’.

Suppose Set A consist of all even numbers such that, A = {2, 4, 6, 8, 10, …} and set B consist of all odd numbers, such that, B = {1, 3, 5, 7, 9, …}. The universal set U consist of all natural numbers, such that, U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10,….}. Therefore, as we know, all the even and odd numbers are a part of natural numbers. Therefore, Set U has all the elements of Set A and Set B.

Gaurav Seth 4 years, 5 months ago

The power set is a set which includes all the subsets including the empty set and the original set itself. It is also a type of sets. If set A = {x,y,z} is a set, then all its subsets {x}, {y}, {z}, {x,y}, {y,z}, {x,z}, {x,y,z} and {} are the elements of powerset, such as:

Power set of A, P(A) = {x}, {y}, {z}, {x,y}, {y,z}, {x,z}, {x,y,z} and {}

Where P(A) denotes the powerset.

@ Gaurav.. Thanks ?

Gaurav Seth 4 years, 5 months ago

 

Are A = {x : x – 5 = 0} and B = {x : x is a positive  integral root of the equation x2 - 2x - 15} equal sets?

In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others.

1088 is right answer ? this question start from 5th class u don't know how to solve this problem

Gaurav Seth 4 years, 5 months ago

P = Rs. 800 [Amount deposited]

T = 3 years

R = 12%

 

S.I. = PRT/100

S.I. = 800 × 3 × 12/100

S.I. = 8 × 3 × 12

S.I. = 288

 

Amount recieved = Rs. 288 + Rs. 800 {Principal + Simple Interest}

Rs. 1088

Use the formulas Sn=n/2(a+l)

Yogita Ingle 4 years, 5 months ago

The series of odd integers from 1 to 2001 is,1,3,5,7..............,2001

a=1

d=3−1=2

l=2001

an​ = a+(n−1)d

2001=1+(n−1)2

2000=2(n−1)

∴n=1001

Sn​=n/2 ​[a+l]

=1001/2 ​[1+2001]

=10,02,001
