... 29 May 2007 Mathematics Prove the quadratic formula by completing the square. The quadratic equation has the solutions
To prove this, we will complete the square.
Consider the general quadratic equation
with a 0. First divide both sides of the equation by a to get
which leads to
Next complete the square by adding to both sides
Finally we take the square root of both sides:
or
We call this result the Quadratic Formula and normally write...

Table1: Amount of drug in the Bloodstream
Part A
1) Use this information to help you find a suitable function to model this data.
Since the rate of decrease of the drug is directly (approximately) proportional to the amount remaining, so let assume that the function is of type y=ae^ (-kt).
Now when value of t is equal to 0 in that case y is...

...**MATH** PORTFOLIO: CREATING A LOGISTIC MODEL A geometric population growth model takes the from where r is the growth factor and is the population at year n. For example, if the population were to increase annually by 20%, the growth factor is r = 1.2, and this would lead to an exponential growth. If r = 1 the population is stable. A logistic model takes a similar form to the geometric, but the growth factor depends on the size of the population and is variable. The growth factor is often estimated as a linear function by taking estimates of the projected initial growth rate and the eventual population limit.

...Book **Report**/Review, Mathematics Pure **Math** **Report** Introduction From the study of statistical processes, this study investigates the relationship between the height of players and the BMI. It uses random sampling to select 40 samples from the members of the Mosley Hill athletic club. The driving force of this study is the hypothesis that tall people have higher BMI. The results of quantitative analysis are expected to show the relationship between the BMI and the heights of the runners. At the end of the analysis and presentation, the linear regression results will show whether there is positive correlation, negative correlation or null correlation between the two variables. This research...

INTRODUCTION
A mathematical model is an abstract model that uses mathematical language to describe the behavior of a system. It is an accurate representation of the relationship between two or more variables relevant to a given situation or problem
The process of developing such models is known as mathematical modeling. Mathematical models are used particularly in natural sciences and engineering disciplines such as physics, biology and mechanical engineering but also in social sciences such as economics and political science.
**Mathe**matical models can take many forms, including but not limited to dynamical systems, statistical models, differential equations, or game theoretic models. These and other model...

... Statistics Samples The interest is to determine whether the new program established to aid in improving the performance of students has an impact. As such, the sample score is 40 pairs of students. The first sample is the pretest where 40 students who are not involved in the program participate. The second sample is the posttest where 40 students are involved in the program participate. The relationship of these samples is that the pretest has corresponding posttest of the students.
Problem
The problem involves determination of the performance of the students in terms of scores. Thus, when each student (ith) score prior and after participation in the program is xi and yi respectively, it is clear that the pair (xi, yi) gives... Statistics...
