Introduction According to the International Program Center‚ U.S. Census Bureau‚ the total population of the World‚ projected to 03/27/08 at 19:37 GMT (EST+5) is 6‚657‚527‚872. (US Census Bureau) This rapid growth in population means little to most people living in this today’s world but it’s a phenomenon that should be a concern to all. It took from the start of human history to the industrial revolution around 1945 for the population to grow to 2 billion. If we then look at the figures after

There are physical and human geographic factors involved in the origins and growth of different towns and cities in different time periods of the world. In medieval Europe‚ the clearing of land and new techniques in agriculture led to higher food production‚ a rise in population‚ and greater economic freedom. This increase in productivity from the 11th through the 14th centuries led to urbanization. People bought foodstuffs and raw supplies from rural areas and sold items imported from other regions

exhibits and Exponential Growth period during Phase A of the given graph. This is visible from the graph because of the distinct J-shaped curve of the graph‚ this indicates that the curve is Exponential. The curve starts with stable phase not seeming to increase because the growth is slow due to the small population known as the Lag Phase. Then the growth build momentum and grows at an accelerating pace until environmental conditions prevent for their growth‚ this is known as the Exponential Growth Phase

Exponential Functions An exponential function is in which a constant base is raised to a variable power. Exponential functions are used to model changes in population size‚ in the spread of diseases‚ and the growth of investments. They can also accurately predict types of decline typified by radioactive decay. The essence of exponential growth‚ and a characteristic of all exponential growth functions‚ is that they double in size over regular intervals. The most important exponential function is

In mathematics‚ the exponential function is the function ex‚ where e is the number (approximately 2.718281828) such that the function ex is its own derivative.[1][2] The exponential function is used to model a relationship in which a constant change in the independent variable gives the same proportional change (i.e. percentage increase or decrease) in the dependent variable. The function is often written as exp(x)‚ especially when it is impractical to write the independent variable as a superscript
