    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.

    4. Let the number of elements of the sets A and B be p and q respectively. Then the number of relations from the set A to the set B is

    (A) 2p+q

    (B) 2pq

    (C) p + q

    (D) pq

    Ans : (B)

    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.
