This week concepts were of function problems which may include exponentials and logarithms within the functions. With these types of function we can find out information for breaking-even and profit analysis, compound interest, continuous compound interest and doubling time for an investment. Out of these concepts from this week lesson plan, currently understanding and using doubling time for an investment would be the most important.

In this world we live in today, the economy has taken a huge down turn due to major banks making their own share of poor investments. With this down turn in the global economy, many people had their Saving Accounts, 401Ks, and Pensions nearly wiped out. All these may be different types of investments we use to help pay for retirement, but they are essential to being able to retire at an early enough age. Otherwise a person would only have to look forward to working during their own golden years instead of taking it easy.

With the concept of doubling time for an investment, we can with some calculation figure out how long it would take for a certain sum of money, known as the principal, would take to double its value in a certain given time period at a certain given fix interest rate all at a certain interval. This is done with the equation A=P( 1+r/m)^mt. With this equation, to figure out t which is time for the principal to double, we can sub in 2P for A since the other known value are r the interest rate and m equals 1. Once we solve the equation for t we find the amount of time needed to double the investment made.

With the concept of this function, doubling time for an investment in use, a person can now safely and accurately predict the amount of time for growth in their investments. Within this global economic down turn, knowing and planning a financially secure future has become important for anyone in the general society. If more people were able to use this concept of doubling time for an investment, the...

The Body Mass Index (BMI) is an indicator to help people to determine if they might have a longer life span than average, are probably not overweight, are probably overweight, or are obese. The intervals for each are from 17 to 22, 23 to 24.999, 25 to 29.9, and over 30 respectively. Notice that it is between 17 and 22. That is not inclusive but rather a...

...the same base.
When an exponential equation has both sides of the equation as the same base one needs to rewrite the equation in the form of bM=bN. For instance, 24x-3=8. To make this the same base we need to make 8 a base of two by writing it as 2^3. Then we have 24x-3=23. Then we get rid of the base and get 4x-3=3. Finally we solve for x.
4x-3=3
4x=6
x=23
120. Explain how to solve an exponential equation when both sides cannot be written as a power of the same base....

In Elementary Algebra we have learned how to solve systems of equations. The solution to a system of linear equations is the point where the graphs of the lines intersect. The solution to a system of linear inequalities is every point in a region of the graph where the inequalities overlap, rather than the point of...

For the example of a ball being thrown up into the sky and then landing on the ground, we can model a quadratic equation to show the path of the projectile at various points in time (projectile motion). That is to say, each point plotted on the graph (parabola) will be a measurement to this effect:
Suppose a ball is thrown into the sky at a velocity of 64ft/sec...

Introduction
In this paper I will be discussing on radical formulas and how to solve for the formula that is given as C = 4d^-1/3b where d is the displacement in pounds and b is the beam width in feet. The exponent of -1/3 means that the cube root of d will be taken and then the reciprocal of the number will be used in the multiplication. These rules include accurately finding...
