The converse of the above statement is ‘If x � 8, then x � 3.’

The converse is false.

(c) Premise 1: If set M is a subset of set N, then M � N = M.

Premise 2: M � N ≠ M Conclusion: Set M is not a subset

∴ m = – 2—5

Answer: A

(a) mDE

= – 1—3

The equation of DE is y = mx + c, i.e.

y = – 1—3

x + c

Since DE passes through point D(–2, 3), x = –2 and y = 3.

3 = – 1—3

(–2) + c

c = 3 – 2—3

= 7—3

Hence, the equation of DE is

y = – 1—3

x + 7—3

.

At the x-axis, y = 0.

0 = – 1—3

x + 7—3

0 = –x + 7 x = 7 ∴ x-intercept = 7

(b) G is point (–2, 0). The equation of GF is y = mx + c, i.e.

y = – 1—3

Since GF passes through point G(–2, 0), x = –2 and y = 3.

0 = – 1—3

(–2) + c

c = – 2—3

Hence, the equation of GF is

The y–intercept of y = –2x3 – 9 is –9. Hence, the graph of y = –2x3 – 9 is as

shown below.

Answer: D

Paper 2 2 For y � –2x + 4, shade above the straight

line y = –2x + 4 and it should be a solid line.

For y � x + 1, shade below the straight line

y = x + 1 and it should be a solid line. For x � 4, shade to the left of the straight

line x = 4 and it should be a dashed line.

The region which satisfies all the given inequalities is as follows.

3 (a) When x = –1, y = 8 – (–1)3 = 9 When x = 1.5, y = 8 – (1.5)3 = 4.625(b)

Form 5 – Chapter 9 Earth as a SpherePassport To Success

(Fully–worked Solutions)

Paper 1 1

Since the longitude of point H is 35°E, ∠GOH = 35°.

Since the difference in longitude between point F and point H is 100°, ∠FOH = 100°.

∴ ∠GOF = 100° – 35° = 65° Therefore, the longitude of point F is 65°W.

Hence, the longitude of point J is(180 – 65)°E = 115°E

Answer: B

2

Since the difference in latitude between point D and point F is 90°, then

∠BOF = 90° – 50° = 40°

Therefore, ∠AOH = 40° because FOH is the diameter of the earth.

Hence, the latitude of point H is 40°N.

Answer: A

Paper 2 3

(a) Longitude of point P = (180 – 55)°E = 125°E

(b) Distance of MT = (55 + 10) × 60 × cos 42° = 2898.3 n.m.

(c) Distance of MQ = 4740 n.m. ∠MOQ × 60 = 4740
