guys please help me how to prepare for english and hindi exam .my exam is starting from 2nd march.i didnt go to school this session .

is there any condition for n to be an integer

a small mistake in last fifth line it is

d>30-3d sorry for that

this quest requires some concept of function chapter

let the no be

A-d, A, A+d, b (in increasing order)

as given b-(A-d)=30

b=30+A-d now numbers

A-d, A, A+d, 30+A-d

apply gm formula

A*(30+A-d)=(A+d)^2

........after solving u will get

, as A>0 then

10-d>0......., 10>d

and all terms are postive thus d>0 and it must be divisible by 3 because A is a integer

so we have options for d ------ 3, 6, 9

but A-d>0 (all terms are +VE)

A>d,

d>30-d , d>7.5

so finally we will take d=9 and then

A=27 numbers are

18 ,27 ,36, 48

their sum =129

really nice

he do any crime and get caught in the jail and do second crime of breaking jail and going outside

he do 45 crime outside and 45 times break jail which is also a crime

my answer is right because you didnt mentioned about common difference to be a positive integer .thus i considere a c.d. a positive real number

which is equal to 0.00000..........................................01

which is very small value

is there anyone other than ronnie who says i m wrong

I WAS RIGHT OR WRONG

i forgot to write in few places so sorry for that

i dont know i m right or wrong

if we have to consider minimum postitive common difference then

c.d.=

it is such a small quantity such that

so a1+a5+a10+a15+a19+a24=225

6 *(a1)=225

a1=225/6

and sum of 24 terms

a1+a2+a3+...........+a24

=24*(a1)

=24*225/6

=900

a little bit mistake ,but concept of you two is exactly right,only this matters

a little bit mistake ,but concept of you two is exactly right,only this matters

i dont know i m right or wrong

alpha=A and beta=B

if A and B are roots of a quadratic eq then quadratic eq is given by

(x-A)(x-B)=0

x^2 -(A+B)x +AB=0

comparing it with our given eq we get

A+B=1 and AB=1 now

=

=1+

clear me first that there are 5 pairs of diff shoes or 5 diff shoes

question is this

$\hspace{-16}$If $\mathbf{a>b>c}$ and $\mathbf{a,b,c}$ are the Roots of the equation\\\\ $\mathbf{x^3-2x^2-x+1=0}$\;.Then value of $\mathbf{a^2b+b^2c+c^2a=}$$

cubic polynomial equation

I dont know i am right or wrong

answer is b

because the direction of force of repulsion or attraction is always perpendicular to surface separating two medium
