Statement 1: Line `(x-1)/1=(y-0)/2=(z2)/(-1)` lies in the plane `2x-3y-4z-10=0.` Statement 2: if line ` vec r= vec a+lambda vec b` lies in the plane `
Correct Answer - c Statement 2 is true as when the line lies in the plane, vector `vecb` along which the line is directed is perpendicular to the normal `vecc` of...

If each of the points `(x-1,4),(-2,y_1)` lies on the line joining the points `(2,-1)a n d(5,-3)` , then the point `P(x_1,y_1)` lies on the line. `6(x+
Correct Answer - B The equation of the line joining the points (2,-1) and (5,-3) is given by `y+1 = (-1+3)/(2-5)(x-2)` ` "or " 2x+3y-1 = 0 " " (1)` Since...

The center of a rectangular hyperbola lies on the line `y=2xdot` If one of the asymptotes is `x+y+c=0` , then the other asymptote is `6x+3y-4c=0` (b)
Correct Answer - D The asymptotes of a rectangular hyperbola are perpendicular to each other. Given one asymptote `x+y+c=0` Let the other asymptote be `x-y+lambda=0` We also know that the asymptotes...

Let `f(x)` be a quadratic expression such that `f(-1)+f(2)=0`. If one root of `f(x)=0` is `3`, then the other root of `f(x)=0` lies in (A) `(-oo,-3)`
Correct Answer - B `(b)` Since one root is `3`, let `f(x)=(x-3)(ax+b)` `implies f(x)=ax^(2)+(b-3a)x-3b`……….`(1)` Given, `f(-1)+f(2)=0` `implies (a+(3a-b)-3b)+(4a+2b-6a-3b)=0` `implies 2a-5b=0` `implies (b)/(a)=(2)/(5)` ………..`(2)` Now, product of roots `=(-3b)/(a)=-3((2)/(5))` since one root...
