Mathematical Modeling of Urban Population Changes
Background of Issue
The growth of population is the issue that caused widespread concern in the world now. As the world’s top 1 populous country, China’s population problem becoming more prominent. Because of the base of large population, although China has implemented the one-child policy to practice family planning, population is still increasing greatly. This huge population pressure has brought a series of problems on China’s social, political, economic, health, employment, etc. therefore, research and solve the population problem is particularity important for China. [3]Usually people will notice that in newspapers about population growth forecast, when it comes to the end of this century or the middle of next century, the whole world or a certain region’s population will reach XX billions. It is important to note that the number of population forecast in the each newspaper will show large difference for the same time, it’s clearly due to result of using different mathematical models in population calculation.

As the human society entered the 20th century, the rapid development in science and technology has made productivity improved strongly, meanwhile, the world’s population is growing in an unprecedented scale. Every unit time for increasing billion in population, has been shorten from one hundred years to two or three decades. The earth we live on, has been carrying its’ 6 billion people entered into the 21 century. For quite a long time, human reproductions has been spontaneously, only because of the rapid expansion of population and dramatically worsen of environment quality, people just suddenly come to realize the truth that it is extremely urgent to research the relationship between human and nature, the variation trend of population, and how to control it.

Introduction
Mathematics finds its root way back more than 5000 years. Mathematics has helped people solve complex problems, represent different problems and transfer knowledge and skill about the different problems. Mathematical models have often being developed to solve and represent these problems especially in natural sciences and engineering disciplines (Arnold 2000). Mathematical models can be defined as a...

...Mathematicalmodeling is commonly used to predict the
behavior of phenomena in the environment. Basically,
it involves analyzing a set of points from given data
by plotting them, finding a line of "best fit" through
these points, and then using the resulting graph to
evaluate any given point. Models are useful in
hypothesizing the future behavior of populations,
investments, businesses, and many other things that
are characterized by...

...also stated in the this song, “36-24-36? Ha ha, only if she's 5'3”. Based on the height and specific measurements we can infer that he favors the physique of urban models. Amber Rose, Rosa Acosta, Kimbella, and Stephanie Santiago are currently the first class urban models in the hip hop industry. Urban models promote themselves in the urban era to the elite of the hip-hop industry. Each of these women are all known for having...

...the pattern of populationchange in the UK?
There are many different components that all add together for the reason why population does change in a specific location. This change is considered ‘dynamic’ as it is constantly changing due to many factors that are always effecting the rate of populationchange.
One of the biggest influences of populationchange would be...

...hapter 8 Homework (EXPLAIN YOUR ANSWERS)
One point questions:
1. a) How can time be incorporated into the theory of consumer behavior (think opportunity costs)?
Time also has a value, so it also should be considered in decision making and utility maximization. The total price of a product should also include the time spent in consuming the product. (how much you make per hour). Usually when people consider their time, their consumer behavior appears to be more rationale.
b) Explain...

...around us.
MathematicalModeling
As we approach day to day life we often need to quantify the things around us, giving structure and numeric value to various situations. This ability to add structure enables us to make choices based on patterns we see that are weighted and systematic. With this structure in place we can model and even predict behavior to make decisions. Adding a numerical structure to a real world situation is called...
