If the 4 points made by intersection of lines 2x-y+1=0,x-2y+3=0 with the coordinate axes are concyclic then centre of circle is (A) ((7)/(4),(5)/(4))(B)((7)/(4),(-5)/(4))(C)((-7)/(4),(5)/(4))(D)((-7)/(4),(-5)/(4))

If p/q = 5/7 then (3p)/(4q) =square

Find: d. 4 (4)/(7) xx 5 (3)/(5)

Let the polynomials be (1) -13q^(5) + 4q^(2) + 12q (2) (x^(2) + 4 ) ( x^(2) + 9) (3) 4q^(8) - q^(6) + q^(2) (4) - ( 5)/( 7) y^(12) + y^(3) + y^(5) Then ascending order of their degree is

4(4)/(5)-:6(2)/(5)=?(3)/(4) (b) (5)/(7) (c) (5)/(8)(d)(7)/(11) (e) None of these

If the sides of the triangle are p,q,sqrt(p^(2)+q^(2)+pq,) then the greatest angle is : a) (pi)/(2) b) (5pi)/(4) c) (2pi)/(3) d) (7pi )/(4)
