Class 11th

v = t – 4

 s =

s = 8 + 8 = 16m/s

V_avg = 16/8 = 8m/s

The different types of sets covered in this chapter are - Empty Set, Singleton Set, Finite Set, Infinite Set, Equal Sets, Equivalent Sets, Subset, Proper Subset, Universal Set, Power Set, and Disjoint Sets.

Union (? ) in sets means "or". It gives a set of all unique elements of two or more sets. Intersection (? ) means "and". It includes all the common elements of two or more sets.

Mathematics in Class 11 is considered tough as compared to Class 10 as it marks a notable leap in the abstractness and complexity. However, regular practice can help you to master the Maths Class 11 including the chapter 1 sets.

The universal set U includes the set of all natural numbers. It includes both the even and odd numbers. U= {1,2,3,4,5,6,7,8,9,10.}. U comprises all elements of Set A and Set B.

Sets is a collection of objects or members which are distinct objects. Normally, the objects are listed within curly braces {}. Example of a set - set of vowels in English - {a, e, i, o, u). Sets class 11 includes multiple exercises on sets concepts. 

K $=\frac{4\sqrt[]{3}}{\sqrt[]{3}x+y}$ $\frac{\text{exception 25:}}{\text{exception 25:}}$

K = $\frac{\sqrt[]{3}x-y}{4\sqrt[]{3}}$ $\frac{\text{exception 25:}}{\text{exception 25:}}$

$\therefore \frac{4\sqrt[]{3}}{\sqrt[]{3}x+y}=\frac{\sqrt[]{3}x-y}{4\sqrt[]{3}}$

$\frac{x^2}{16}-\frac{y^2}{48}=1$

48 = 16 (e2 – 1)

$e=\sqrt[]{4}=2$

  $\frac{GM}{{\left(3R/2\right)}^2}=\frac{GM}{R^3}*r$

$\Rightarrow OA=\frac{4R}{9}=r$

$AB=R-\frac{4R}{9}=\frac{5R}{9}\Rightarrow OA:AB=4:5=x:y\Rightarrow x=4$

Let a_n be the side of square A_n

$a_n=\sqrt[]{2}{a}_{n+1}$

a₁ = 12

a_n = 12 $*{\left(\frac{1}{\sqrt[]{2}}\right)}^{n-1}$

${\left(a_n\right)}^2<1$

$\frac{144}{2^{\left(n-1\right)}}<1$

$\Rightarrow 2^{\left(n-1\right)}>144$

$\Rightarrow n-1\ge 8$

$\Rightarrow n\ge 9$

 Kindly go through the solution

 $v=\omega \sqrt[]{A^2-s^2}\Rightarrow \frac{A\omega }{2}=\omega \sqrt[]{A^2-s^2}\Rightarrow s=\frac{\sqrt[]{3}A}{2}\Rightarrow x=3$
