ok...
So here we can use 22/7 , but that is not the exact answer?
If the RHS is similar to that 1 and 2 ,,,
hw is x=1 and y=0?
So 22/7 cant be used for pi any where???
Top row vector????
this vector means
????
Why Some Times?
u edited your post ????????
good way of telling me what is rt ???? Got it ...
thats good then
Ok...
got it!!!!!!!!!!!!
Thank you so much !!!!!!!!!!!!!
25%participate in both dance and drama
what is this rt?
Doesnt that come under cyclic symmetry?
If x^2 + 1/x^2 = 1 ...
What about x^3 + 1/x^3
Can you tell me the quick trick???? Please
Got it !!!!!!!!!!!!!!
we get n^2 - n -9900 = 0
after this..??
In a school day program 60% students participate in dance, 25% in drama and dance. Find the
percentage of students who participate in drama only.
I used v= pi r^2 h
11000=22/7 × r^2 × 35
r^2=11000/35 × 7/22
r^2= root 100
r=10
if r=10 d=2r
d=20
Am i wrong?
If x^2 = 5x then the value of x are
A) 0 B) 0 & 5 C) 5 D) 0 & - 5
2.The expressions with HCF & LCM as 4xy^2 & 8x^3y^5 is
A) 4x^2y^5 & 8x^3y^2 B) 4xy^5 & 8x^3y^2 C) 4x^2y^5 & 8xy^2 D) 4y^5 & 8y^2
3.Quadratic equation with roots ( 3 + or - root 2 ) is
A) x^2 + 6x 7 = 0 B) x^2 6x + 7 =0 C) x^2 + 6x 7 = 0 D) x^2 6x 7 = 0
4.In a graph , straight line intersects the parabola at(3,9) & (1, 1) Then the equation is
A) x^22x+3=0 B) x^2+2x3=0 C) x^23x+2=0 D) x^22x3=0
5.Relation between a cone and a cylinder with same radius and height is
A) cone = cylinder B) 3 cone = cylinder C) cone =3 cylinder D) All the above
6.The lateral surface area of a roller is 5sqm. Find the number of revolutions that it does
to cover a feild of 1000 sqm
A) 100 B) 200 C) 50 D) 500
please explain along with the answer
if we use the equation time=distance/speed , and the speed as x
we get,
first time=240/x
after increaing the speed, time= 240/x+2
240/x - 240/x + 2 = 1/2
I got the answer by this way
Can we solve it by this way ?? Is this method correct??
I did'nt understand why you multiplied by 2s(s+2),, and the following steps;
Please explain why you did it ??
how did you get that 12?
I dont know .. The question is given like this
If the ratio between first three terms and first six terms of GP is 125 : 152. Find the common ratio.
May be that SUM OF must be added... But it is not given in the book..
Even i got that
But i was not sure about it..
Thank you
How did you get ??
