Find the radius of director circle of the conic, which is locus of the point intersection of straight lines x 25 - y 24 =m, x 25 + y 24 = 1 m

Correct answer

07

Step-by-step solution

eliminating m from given equations by mutliplying the above two equations we have we get x ^2 (25)^2 - y ^2 (24)^2 =1 , Radius of director circle = a^2-b^2 clearly its director circle will have radius =7
