Assignment 1 brief

Assignment written by Steve Atherton Date 26/08/2014

Assignment IV’d by Giles Dawes Date 1/09/2014

P1 Use a scientific calculator to perform calculations and apply manual checks to

results (where asked to).

Give answers to the stated levels of accuracy and in the correct units.

1 Calculate your answer to a, b and c without a calculator.

Show your working out. If you only write the answer you will fail.

a) 2 + 3 x 15 – 4 b) 33 – (18 – 23 ÷ 2) c) 105 ÷ 103

2 Work out the following using a calculator.

a) 40 – p 3.52 b) 2¼ x 3½ c) 13 + 122 – v121 d) 6! – 4!

3 The volume of a cone is given by V = 1/3 p r2 h

Calculate the volume if the radius, r is 100mm and the height h, is 150mm.

Give your answer to the nearest mm3

4 A rectangular piece of land has sides length 32.15m by 16.45m

a) Calculate an estimated answer for the area, show your working out.

b) Calculate an exact answer to the area.

c) Give your answer to the nearest square metre.

P2 Use standard mathematical techniques to simplify expressions and

solve problems using linear formulae

1 Simplify the following expressions

a) 3ab + 4bc + 2ab – bc b) 4x + 19 – 5x – 8 + 7x

c) 9 – 3(1 + 7c) d) 7(2f – 1) – 1(6f + 3)

2 Solve the following equations showing your working out. Check your answers by

substituting them in the original equation. Show your checking out for a) and b).

a) 8x + 12 = 54 b) 40 – 4y = y

c) 3x + 5 = 10 d) 5(x + 2) – 3(x – 5) = 29

2

M1 Use algebraic methods to solve linear, quadratic, simultaneous linear and quadratic

equations.

1 Solve these simultaneous equation using a recognised algebraic method.

a) 3x + 2y = 13 and 6x + y = 20

b) y = 2x + 5 and x² + 4y = 5

2 Produce simultaneous linear equations from the information below then solve them.

3 kilos of nails and 2 kilos of screws cost £25.60

4 kilos of nails and 1 kilo of screws cost £23.30

What is the cost of a) 1kg of screws and b) 1kg of nails?

3 Solve the following quadratic equations using a recognised method.

a) x2 + 6x + 5 = 0 b) x² – 13x + 22 = 0 c) m² = 6m + 27

D1 Independently carry out checks on calculations using relevant alternative mathematical methods and make appropriate judgments on the outcome.

Solve M1 questions number 1a and 3 using an alternative method and make

appropriate judgments on your answers.

Apply appropriate algebraic methods to find areas and volumes for one 2D and one 3D

complex problem.

1 A swimming pool is to be built on the plot of land shown below.

The pool is to be 1.5m deep and is a rectangle 20 m by 10 m with a semi-circular end. Around the pool is a paved area 1.5 m wide. The remaining area is to be lawn.

The pool is to be tiled with light blue tiles, with an oval shape on the bottom tiled in dark blue, measuring 15 m x 8 m

Calculate:
