Answer 1

Answer:

1) B) 7

2) C) (0,0)

Step-by-step explanation:

1) Any polynomial with degree x has x number of roots.

Here, x=7

so, no. of roots = 7

2) y=2at

   =>dy/dt=2a

   x=at²

   =>dx/dt=2at=y

   so,

   dy/dx=(dy/dt) / (dx/dt) = 2a/y

   but tangent ⊥ar to x-axis,

   so, tangent will be parallel to y-axis

   so, slope of tangent = slope of y-axis

  =>2a/y=0

  =>a=0

  so,

  x = at² = 0(t²) = 0

  y = 2at = 2(0)t = 0

 Hence,

 Pont of contact is (0,0) i.e origin.
