G/LM/Jun24/G4005/E7 7357/2 Section A Answer all questions in the spaces provided. 1 One of the equations below is the equation of a circle. Identify this equation. [1 mark] box Tick () one box. (x + 1)2 – (y + 2)2 = –36 (x + 1)2 – (y + 2)2 = 36 (x + 1)2 + (y + 2)2 = –36 (x + 1)2 + (y + 2)2 = 36 2 The graph of y = f (x) intersects the x‑axis at (–3, 0), (0, 0) and (2, 0) as shown in the diagram below. box y A – 3 The shaded region A has an area of 189 The shaded region B has an area of 64 2 Find the value of ∫–3 f (x) dx Circle your answer. 2 x B [1 mark] –253 –125 125 253 Turn over for the next question Turn over U 3 Solve the inequality (1 – x)(x – 4) 0 [1 mark] box Tick () one box. {x : x 1} {x : x 4} {x : x 1} ∩ {x : x 4} {x : x 1} {x : x ≥ 4} {x : x 1} ∩ {x : x ≥ 4} 4 Use logarithms to solve the equation 5x–2 = 71570 box Give your answer to two decimal places. [3 marks] Turn over for the next question Turn over U 5 Given that find dy dx y = x3 sin x [3 marks] box 6 It is given that and that θ is obtuse. (2 sin θ + 3 cos θ)2 + (6 sin θ – cos θ)2 = 30 box Find the exact value of sin θ. Fully justify your answer. [6 marks] Turn over U 7 On the first day of each month, Kate pays £50 into a savings account. Interest is paid on the total amount in the account on the last day of each month. The interest rate is 0.2% At the end of the nth month, the total amount of money in Kate’s savings account is £Tn Kate correctly calculates T1 and T2 as shown below: T1 = 50 × 1.002 = 50.10 T2 = (T1 + 50) × 1.002 = ((50 × 1.002) + 50) × 1.002 = 50 × 1.0022 + 50 × 1.002 ≈ 100.30 box 7 (a) Show that T3 is given by T3 = 50 × 1.0023 + 50 × 1.0022 + 50 × 1.002 [1 mark] 7 (b) Kate uses her method to correctly calculate how much money she can expect to have in her savings account at the end of 10 years. 7 (b) (i) Find the amount of money Kate expects to have in her savings account at the end of 10 years.
