Total: 50 marks · 10 questions. Method marks are awarded for a correct method even where the final answer is wrong. Values read from the graph in Q9 are accepted within about 5 kWh of the value given.
Q1Indices[5]
(a) 93x−1 = 32(3x−1) = 36x−2 and 27x+2 = 33x+6, so 6x − 2 = 3x + 6 and x = 8/3
(a) gradients: −1/2 from the first, −3/k from the second. No solution means they are equal, so −3/k = −1/2 and k = 6
(b) substituting: x2 + (x − 3)2 = 17 gives 2x2 − 6x − 8 = 0, i.e. (x − 4)(x + 1) = 0. x = 4, y = 1 or x = −1, y = −4
Q3Similar solids[5]
(a) length ratio 6 : 9 = 2 : 3, so volume ratio = 8 : 27. Volume of Q = 240 × 27/8 = 810 cm3
(b) surface area ratio = (3/2)2 = 2.25, so the area painted on Q is 225 % of that on P
(c) 810 cm3 of water cannot fit into a 240 cm3 container, so container P overflows
Q4Similar triangles[5]
(a) ∠DAE = ∠BAC (common angle) and ∠ADE = ∠ABC (corresponding angles, DE ∥ BC). Two equal angles, so triangle ADE is similar to triangle ABC (AA similarity test)
(b) AD/AB = 6/10 = 3/5, so BC = 9 ÷ 3/5 = 15 cm
(c) area ratio = (3/5)2 = 9/25, so area of ABC = 27 ÷ 9/25 = 75 cm2
Q5Trigonometry[5]
(a) ST = 45 tan 32° = 28.1 m (3 s.f.)
(b) the flag is 28.119 − 5 = 23.119 m above the ground, so the angle = tan−1(23.119/45) = 27.2° (1 d.p.)
(c) PS = 45 ÷ cos 32° = 53.1 m (3 s.f.)
Q6Graph sketching[5]
(a) y = −2x + 4: a straight line falling from (0, 4) to (2, 0)
(b) y = 3: a horizontal line through (0, 3)
(c) y = x2 − 4: an upward parabola cutting the x-axis at (−2, 0) and (2, 0), the y-axis at (0, −4), with turning point (0, −4)
Q7Graph reading in context[5]
(a) $4. This is the fixed booking fee, charged before any distance is travelled
(b) gradient = (22 − 4)/10 = 1.8, so the fare rises by $1.80 for each kilometre travelled
(c) C = 1.8d + 4
(d) C = 1.8(15) + 4 = $31
Q8Completing the square[5]
(a) x2 − 6x + 2 = (x − 3)2 − 9 + 2 = (x − 3)2 − 7
(b) turning point (3, −7)
(c) (x − 3)2 − 7 = 1 gives (x − 3)2 = 8, so x = 3 ± 2√2 = 0.17 or 5.83 (2 d.p.)
Q9Statistics[5]
(a) the median is the 60th value; read from the curve, ≈ 332 kWh
(b) lower quartile (30th value) ≈ 285 kWh and upper quartile (90th value) ≈ 385 kWh, so the interquartile range ≈ 100 kWh
(c) the survey does not support the claim: the median from the survey (≈ 332 kWh) is higher than 300 kWh
Q10Quadratic word problem[5]
(a) x(x + 3) = 150, which expands to x2 + 3x − 150 = 0
(b) x = [−3 ± √(9 + 600)] / 2 = [−3 ± √609] / 2, so x = 10.8 or −13.8; the negative value is rejected
