The shortest distance between the line L_1=(hat i - hat j hat k) lambda (2 hat i - 14 hat j 5 hat k) and L_2=(hat j hat k) mu (-2 hat i - 4 hat 7 hat) then L_1 and L_2 is

A line is a drawn from P(4,3) to meet the lines L_1 and l_2 given by 3x+4y+5=0 and 3x+4y+15=0 at points A and B respectively. From A , a line perpendicular to L is drawn meeting the line L_2 at A_1 Similarly, from point B_1 Thus a parallelogram AA_1 B B_1 is formed. Then the equation of L so that the area of the parallelogram AA_1 B B_1 is the least is (a) x-7y+17=0 (b) 7x+y+31=0 (c) x-7y-17=0 (d) x+7y-31=0

In the morning, a milkman filled 5(1/2) L of milk in his can. He sold to Renu, Kamla and Renuka 3/4 L each, to Shadma he sold 7/8 L and to Jassi he gave 1(1/2) L. How much milk is left in the can?

If L _(1) : 4x - 3y + 7=0 and L _(2) : 8x - 6y -1 =0 are two tangents to a circle C, length of whose diameters is d, then d is equal to

Find the L.C.M of 4/5, 2/3 and 5/7

Let A be the vertex and L the length of the latus rectum of the parabola,y^(2)-2y-4x-7=0 The equation of the parabola with A as vertex 2L the length of the latus rectum and the axis at right angles to that of the given curve is:
