Question 1 · Coordinate geometry

Find the distance between the points (−4, 5) and (16, 26).

  1. A. 58
  2. B. 28
  3. C. 29 ✓
  4. D. 30

Answer: 29. Distance = √(20² + 21²) = √841 = 29.

Question 2 · Quadratic equations

What is the larger root of x² − 12x + 32 = 0?

  1. A. 8 ✓
  2. B. 32
  3. C. 12
  4. D. 4

Answer: 8. x² − 12x + 32 = (x − 8)(x − 4) = 0, so the roots are 8 and 4. The larger is 8.

Question 3 · Probability

A bag holds 1 red, 3 blue and 2 green balls. One ball is picked at random. What is the probability it is red?

  1. A. 1/6 ✓
  2. B. 1/7
  3. C. 1/2
  4. D. 1/3

Answer: 1/6. Probability = favourable ÷ total = 1/6.

Question 4 · Trigonometry

Find the value of sin 30° + cos 60°.

  1. A. 1 ✓
  2. B. 5/4
  3. C. 1/2
  4. D. 2

Answer: 1. Use sin 30° = ½, cos 60° = ½, tan 45° = 1, sin 90° = 1 and cos 0° = 1. sin 30° + cos 60° = 1.

Question 5 · Pythagoras theorem

A right-angled triangle has legs of 15 cm and 36 cm. How long is the hypotenuse?

  1. A. 51 cm
  2. B. 39 cm ✓
  3. C. 38 cm
  4. D. 78 cm

Answer: 39 cm. c² = 15² + 36² = 225 + 1296 = 1521, so c = 39 cm.
