- 1.A company's weekly profit, in £, is modelled by y = f(x), where x is the number of weeks since launch. The graph of y = f(x) has a maximum at (10, 45000). A rival company uses the same marketing strategy but starts trading 6 weeks later and has fixed costs £8000 higher every week, so its profit is modelled by y = f(x − 6) − 8000. In which week does the rival's maximum weekly profit occur, and what is it?
- 2.Work out the gradient of the straight line with equation y = (2x/5) − 3.
- 3.Solve 2x² − 7x + 3 = 0.
- 4.Work out the equation of the straight line through the points (−3, 4) and (1, −8).
- 5.The diagram shows two curves drawn on the same grid. Curve A is the graph of . Which equation could represent curve B?
- 6.A rule turns each input into an output. An input of 0 gives an output of −1, an input of 1 gives an output of 1, and an input of 2 gives an output of 3. Work out the rule, writing the input as x and the output as y.
- 7.A stack of firewood has 3 logs in the top layer. Each layer below has 4 more logs than the layer above it. Work out the number of logs in the 6th layer from the top.
- 8.A geometric sequence begins 80, 40, 20, 10, ... Work out the next term in the sequence.
- 9.A graph shows the total monthly cost of a mobile phone tariff against the number of minutes of calls. The line starts at £12 and stays level until 200 minutes, then rises by 5p for each further minute of calls. Use the graph to work out the total cost of a month in which 250 minutes of calls are made.
- 10.On Monday, a runner covers 15 km in 2.5 hours. On Tuesday, she covers 12 km in 1.5 hours. Using the formula speed = distance ÷ time, work out on which day she ran faster, and by how much.
- 11.The table shows the height, in metres, of a firework rocket at various times, in seconds, during its flight: 40 at t = 2, 54 at t = 3, and 60 at t = 4. Use the chord between t = 2 and t = 4 to estimate the gradient of the height-time graph at t = 3, stating the correct units.
- 12.The graph of y = x³ − 5x is reflected in the y-axis. Work out the equation of the image.y = x
- 13.Solve the inequality x² ≥ 16, giving your answer using set notation.
- 14.A straight line passes through the points (1, 3) and (2, 5). Work out the equation of the line.
- 15.The formula connecting speed, distance and time is v = s ÷ t. Work out v, in km/h, when s = 180 and t = 4.
