@mickym said: the no. of common tangents to the circles x2 + y2 – 2x – 2y – 23 = 0 and x2 + y2 – 12x – 26y + 141 = 0 ?

bhai ek r mil jaaye to q easy ho jaaye
Bro assume R
then tell wat will be the side in terms of R
@watsnew24 said:
Easy hai bro just circle wali eqn yaad honi chaiye
@watsnew24 said:
i will go with C
no......:(

2R/R+2

bhai similar triangle ka formula se jo cube ki height wahi upar wale triangle ka base radius

no......
to 1.25 minus

answer kya hai......

(x-x1)^2 + (y-y1)^2 = r^2

@007pagal sunny leone wale may even though ki jagah sirf though hoga...

Although vs Though vs Even though


Although - linking word - expresses the idea of contrast.


e.g. - Although Amit has a car, he doesn't often drive it.


The clause with although can come at the end.


e.g. - Although the cafe was crowded, we found a table. OR We found a table, although the cafe was crowded.


Though - is informal. It means the same as although.


e.g. - Though / Although I liked the sweater, I decided not to buy it.


We can use though at the end of a sentence.


e.g. - I liked the sweater. I decided not to buy it, though.


Even though - is stronger, more emphatic than although.


e.g. -
1). Ram looked quite fresh, even though he'd been playing cricket.
2). Even though you dislike Sanya, you should try to be nice to her.

to 1.25 minusanswer kya hai......
answer is B......and i dont know why.....somebody plz explain this.....
mera bhi 1.25 minus aur 30 seconds bhi....maine A socha tha

bhai ye kaise aaya

ab aapne poocha matlab wrong hi hoga

khair

cube ki height agar x hai to jo upar wala triangle banega uska base bhi x hi hoga(cone mein)

ab 2/2-x = R/x

isko x k liye solve kiya to ye aya
