Complete the table for y = x² - 4x + 1.

Draw the graph of y = x² - 4x + 1 for -1 ⩽ x ⩽ 5.

On the same grid, draw the graph of y = 2 x - 6 for - 1 ⩽ x ⩽ 5.

Use your graphs to solve the equation x² - 4x + 1 = 2x - 6.

Give your answers to 1 decimal place.

An octahedron is formed from two identical square based pyramids. The square bases are stuck together as shown.

The volume of the octahedron is 60 cm³. The length of the side of each pyramid’s square base is 5 cm.

Work out the height h cm of the octahedron. [The volume of a pyramid is × area of base × perpendicular height]

Vector a = and vector b = .

Nine consecutive numbers are written on a 3-by-3 grid. They are arranged, in ascending order, in a spiral as shown.

Karen writes the numbers 3 to 11 on her grid.

The total of the first column is 3 + 10 + 9 = 22.

Karen says

The total of the first column is one less than the total of the second column.

Show that this is correct for Karen’s grid.

Victor says

If any nine consecutive numbers are arranged in ascending order in this spiral on a 3-by-3 grid, the total of the first column will always be one less than the total of the second column.

Prove that Victor is correct.

A sequence is defined by the rule u_n+1 = 5u_n - 15.

If u₃ = 6, calculate

u₅

u₂

Trevor says

Show that Trevor is correct.

(a)........ minutes........ seconds

Claudine cycled a distance of 53 km in 2.7 hours. The distance is measured correct to the nearest km. The time is given correct to 1 decimal place.

Calculate the lower and upper bounds of her average speed.

Give your answers correct to 2 decimal places.

(b) lower bound =........ km / h

upper bound =........ km / h

Dani has a pack of 45 cards. Each card is either red or black.

One-third of the cards in the pack are red.

She picks two cards from the pack, without replacement.

Calculate the probability that Dani picks two black cards.

The histogram shows information about the weights of some of the parcels handled by a delivery company in one month.

Zoe says

There are fewer parcels weighing between 450 g and 700 g than parcels weighing between 300 g and 450 g.

Is Zoe correct? Show how you decide.

The delivery company delivered 6500 parcels weighing between 50 g and 100 g.

Complete the histogram to show this information.

Zoe uses the histogram to calculate the number of parcels weighing between 200 g and 250 g.

Explain why Zoe’s answer is unlikely to be reliable.

In the diagram,

• A, B and C are points on the circumference of a circle

• O is the centre of the circle

• angle OAB = 15°

• angle BCO = 10°.

Calculate the acute angle AOC.

In the diagram,

• E, F and D are points on the circumference of the circle

• G, D and H lie on a tangent to the circle

• angle EFD = 55°

• angle FDE = 43°.

Explain why angle HDF is 82°.
