A tangent at point P on a circle with centre O intersects a secant through O at point Q. If OP = 7 cm and OQ = 25 cm, then PQ is:

Maximize Z = 3x + 4y subject to x + y ≤ 4, x ≥ 0, y ≥ 0. The maximum value of Z is:

If the roots of the equation x² − kx + 16 = 0 are equal, then the value of k is:

The value of lim(x→0) sin(3x)/x is:

Add: 2/3 + 1/6.
