The pie chart below summarises the average weekly expenditure by a sample of families on food and drink. The whole circle represents 100% of the expenditure. The circle is then divided into â€˜segmentsâ€™, and the area of each segment represents a fraction or pe

1. A coordinate system provides a systematic means of specifying the position of a particle. A system in one dimension involves choosing an origin and a positive direction in which values of the position coordinate increase. Values of the position coordinate are positive or negative numbers multiplied by an appropriate unit of length, usually the SI unit of length, the metre (m).

2. The movement of a particle along a line can be described graphically by plotting values of the particle's

Aims The main aim of this section is to look at some different ways of measuring price increases.

In this section you will be looking at measuring price changes using price indices. In order to do this you will need to understand the concept of a price ratio.

Introduction

Graphs are a common way of presenting information. However, like any other type of representation, graphs rely on shared understandings of symbols and styles to convey meaning. Also, graphs are normally drawn specifically with the intention of presenting information in a particularly favourable or unfavourable light, to convince you of an argument or to influence your decisions.

Suppose that a manager is planning or exploring the possibility of a change (in working practices, for example). The manager can represent the current situation as a horizontal line. The driving forces, those forces or reasons that are supportive of a change, can be represented as downward-pointing arrows that are seeking to push the line. The restraining forces, those forces or reasons that are likely to resist the change, can then be represented by upward-pointing arrows that are supporting

Experiments as Modus Operandi
Architecture has for too long focused on the presentation of pristine objects and the presentation in drawing form. A critical understanding of the field, however, necessitates a reevaluation of the roles of the process involved in the production of building. Rather than emphasizing surface appearances, an architecture rooted in process aims ultimately at revealing the fundamental and deep structures inherent within the making of architecture. One of the primary tasks of the process is to provok

These minor units are therefore tenths of a centimetre, commonly known as 'millimetres'. (There are 10 millimetres in 1
