- 1.A square tile has an area of 144 cm². Work out the side length of the tile.
- 2.Solve the inequality 3x − 1 ≤ 11.
- 3.How many turning points does the graph of y = x² − 7x + 10 have?y = x² − 7x + 10
- 4.The curve y = 2x² − 12x + 7 has a minimum point. By completing the square, find the value of x at which the minimum occurs.y = 2x² − 12x + 7
- 5.Three consecutive integers add up to 72. Using n for the smallest integer, form an equation and solve it to find the smallest of the three integers.
- 6.Work out the equation of the straight line through the points (−2, 1) and (0, 7).
- 7.A theatre's front row has 18 seats. Each row behind has 4 more seats than the row in front. Which row has exactly 62 seats?
- 8.By completing the square, find the turning point of the curve y = x² + 8x − 3.y = x² + 8x − 3
- 9.A hot air balloon is at a height of 20 m and rises at a steady rate. After 4 minutes it is at a height of 52 m. Work out the rate at which the balloon rises, in metres per minute.
- 10.A number machine multiplies its input by 2 and then subtracts 5. Work out the output when the input is 6.
- 11.A rectangular sheet of metal measures 20 cm by 12 cm. A square of side x cm is cut from each corner and the sides are folded up to make an open box of volume 200 cm³. This gives x³ − 16x² + 60x − 50 = 0, which can be solved using the iterative formula xₙ₊₁ = (16xₙ² − xₙ³ + 50)/60. The starting value is x₀ = 1, so x₁ is the value after the formula has been used once. Work out x₃, and use it to find the longer side of the base of the box correct to 1 decimal place.
- 12.A tap fills a tank at a varying rate. A graph shows the rate of flow, in litres per minute, against time, in minutes. What does the area under this graph represent?
- 13.The 2nd term of a geometric sequence is 6 and the 4th term is 24. Given that all the terms of the sequence are positive, work out the common ratio.
- 14.A machine bought for £2,400 loses 12% of its value every year. After how many complete years does its value first fall below £1,500?
- 15.A zip-line runs from a platform 25 m high to a landing point 5 m high, over a horizontal distance of 40 m. Work out the gradient of the zip-line.
