The tangent to the curve \(y = 4x^{3} + kx^{2} - 6x + 4\) at the point P(1, m) is parallel to the x- axis, where k and m are constants. Find the value of k

A.

3

B.

2

C.

-3

D.

-2

Correct answer is C

\(y = 4x^{3} + kx^{2} - 6x + 4\)

\(\frac{\mathrm d y}{\mathrm d x} = 12x^{2} + 2kx - 6\)

At P(1, m)

\(\frac{\mathrm d y}{\mathrm d x} = 12 + 2k - 6 = 0\) (parallel to the x- axis)

\(6 + 2k = 0 \implies k = -3\)

Find the fourth term of the binomial expansion of \((x - k)^{5}\) in descending powers of x.<

A.

\(10x^{3}k^{2}\)

B.

\(5x^{3}k^{2}\)

C.

\(-5x^{2}k^{3}\)

D.

\(-10x^{2}k^{3}\)

Correct answer is D

\((x - k)^{5} = ^{5}C_{0}x^{5}(-k)^{0} + ^{5}C_{1}x^{4}(-k)^{1} + ...\)

The fourth term in the expansion = \(^{5}C_{4 - 1}(x)^{5 - 3}(-k)^{3 = 10 \times x^{2} \times -k^{3}\)

= \(-10x^{2}k^{3}\)
