Correct Answer: D. The Second World War boosted their morale

Explanation

(a) \(y = 2x^{2} - 7x - 3\)

(b)

(c)(i) Minimum value of y = -9

(ii) \(y = 2x^{2} - 7x - 3\)

Gradient = \(\frac{\mathrm d y}{\mathrm d x} = 4x - 7\)

Gradient at x = 1 : \(4(1) - 7 = 4 - 7 = -3\).

(d) \(2x^{2} - 7x - 5 = x + 4\)

\(2x^{2} - 7x - 5 + 2 = x + 4 + 2\)

\(2x^{2} - 7x - 3 = x + 6\)

\(\implies y = x + 6\)

From the graph, x = -0.9 or 5.

The Limitations to the power of the Governor in the Colonial Administration of Nigeria before the Second World War include:

(viii) Some of the demonstrations, riots, etc., for e.g. the Aba Women's Riot of 1929, etc. was a limitation to the powers of the Governor.

Correct Answer: D. 0.75

Explanation

R.D = \(\frac{\text{volume of liquid displaced}}{\text{volume of water displaced}}\)

= \(\frac{1}{2} - \frac{2}{3} = \frac{1}{2} \times \frac{3}{2} = \frac{3}{4}\)

= 0.75
