Let there be `ngeq3` circles in a plane. The value of `n` for which the number of radical centers is equal to the number of radical axes is (assume that all radical axes and radical centers exist and are different). a. `7` b. `6` c. `5` d. none of these

Let there be n circles no three of which have collinear centres.If the total number of radical axes is equal to total number of possible radical centres,then possible value of n is

ln n(n>=3) circles the centres of no three circles are collinear. If the number of the radical axes of the circles is equal to the number of the radical centres of the circles then n^(2)-4n-5=

2nd idetical coins are arrangeed in a row and the number of ways in which the number of heads is equal to the nuber of tails is 70, then n= (A) 4 (B) 5 (C) 3 (D) none of these

Let a,b,c in N, then number of ordered triplet (a,b,c) such that 5a+6b+3c=50

STATEMENT-1 : If n circles (n ge 3) , no two circles are non-centric and no three centre are collinear and number of radical centre is equal to number of radical axes, then n = 5. and STATEMENT-2 : If no three centres are collinear and no two circles are concentric, then number of radical centre is ""^(n)C_(3) and number of radical axs is ""^(n)C_(2).

Let f(x) = ax^(2)+bx+c where a,b,c are real numbers. If the numbers 2a ,a +b and c are all integers ,then the number of integral values between 1 and 5 that f(x) can takes is______

The radical center of three given circles will be the center of a fourth circle which cuts all the three circles orthogonally.

The number of possible outcomes in a throw of n ordinary dice in which at least one of the die shows and odd number is a.6^(n)-1 b.3^(n)-1 c.6^(n)-3^(n) d.none of these

The radius of the circle which touches the co- ordinates axes and the line 3x+4y=12 is 1 (b) 2 (c) 3 (d) 6

The difference between the place values of 7 and 3 in the number 527435 is 4 (b) 5 (c) 45 (d) 6970 (e) none of these
