If `6x+7y=48` cut at two ponts `A` & `B` origin `(O)` then incentre of `/_\AOB` is (a) `(2,4)` (b) `(4,4)` (c) `(2,2)` (d) `(4,2)`

A line 4x+3y=24 cut the x -axis at point A and cut the y-axis at point B then incentre of triangle OAB is (A)(4,4) (B) (4,3) (C) (3,4) (D) (2,2)

lf 2A= 3B = 4C,then A :B :C is (A) 2 : 3 : 4 (B) 4 : 3 : 2 (C) 6 : 4 : 3 (D) 3 : 4 : 6

The line 7x+4y=28 cuts the coordinate axes at A and B. If O is the origin,then the ortho-centre of OAB is

If A(4,-4) and B(9,6) lies on y^(2)=4x and a point C on arc AOB(O= or ig in) such that the area of /_ACB is maximum then point c is (1)((1)/(4),1) (2) (1,(1)/(4))(3)(1,(1)/(2)) (4) ((1)/(2),1)

The coordinates of the middle point of the chord cut-off by 2x-5y+18=0 by the circle x^(2)+y^(2)-6x+2y-54=0 are (1,4) (b) (2,4) (c) (4,1) (d) (1,1)

If 2x+y=5 and 3x-4y=2, then the value of 2xy is (a) 4 (b) 6 (c) 8 (d) 10

The locus of the centre of a circle which cuts orthogonally the parabola y^(2)=4x at (1,2) will pass through(a) (3,4)(b)(4,3)(c)(5,3) (d) (2,4)

The centroid of triangle is (2,7) and two of its vertices are (4,8) and (-2,6). The third vertex is (0,0) b. (4,7) c. (7,4) d. (7,7)
