If the line `x-1=0` is the directrix of the parabola `y^2-k x+8=0` , then one of the values of `k` is `1/8` (b) 8 (c) 4 (d) `1/4`

If the line x-1=0 is the directrix of the parabola y^(2)-kx+8=0 ,then one of the values of k is (1)/(8)( b) 8 (c) 4 (d) (1)/(4)

the directrix of parabola y^(2)-2x+k=0 is x=1 then k

If the line x-1=0 is the directrix of the parabola y^(2)-kx+8=0 then "k" is A.) 3 B.)-3 C.)4 D.)5

If the line ax+by+c=0 is a tangent to the parabola y^(2)-4y-8x+32=0, then :

If the line y=-(7)/(2) is the directrix of the parabola x^(2)-ky+8=0 , then the sum of all the possible values of k is equal to

If the line x-1=0 is the directrix of the para bola y^(2)-kx+8=0,k!=0 and the parabola intersect the circle y^(2)+x^(2)=4 in two real distinct points,then the value of k is

If the line x + 2y = k is normal to the parabola x^(2) – 4x – 8y + 12 = 0 then the value of k/4 is :
