2. If y = 4x + 3 is parallel to a tangent to the parabola y2 = 12x, then its distance from the normal parallel to the given line is

WBJEE 2014, Mathematics

Ans: (B)

Sol:

We have equation of line,

y = 4x + 3

So, slope of line = 4

Also, a = 3

Equation of normal

y = mx – 2am – am3

y = 4x – 216

3. In a ΔABC, tanA and tanB are the roots of pq(x2 + 1) = r2x. Then ΔABC is

(A) a right angled triangle

(B) an acute angled triangle

(C) an obtuse angled triangle

 (D) an equilateral triangle

Ans: (A)

Sol:

We have equation, pq(x2 + 1) = r2x.

So, pqx2 – r2x + pq = 0

tanA and tanB are the roots of the above equation

Product of roots = tanA. tanB = pq/pq = 1

tanA tanB = 1

So, tan(A+B) is undefined

∴∠C = π / 2

So, ABC is right angled triangle.

Sol:

Number of elements in set A = p

Number of elements in set B = q

Number of relations from the set A to the set B is pq.
