IB Mathemetics SL Portfolio: Logarithmic Bases In this portfolio task‚ I will investigate the rules of logarithms by identifying the logarithmic sequences. After identifying the pattern‚ I will produce a general statement which defines the sequence. I will then test the validity of my general statement by using other values. I will finally conclude the portfolio task by explaining how I arrived to my general statement and its limitations. Consider the following sequences. Write down the next

M. Velas FUNCTIONS OF LEISURE Relation to Increased Production and Consumption The function of leisure is largely determined by the kind and amount of free time and by the ideas of the age. When spare time consists of short breaks between long periods of sustained labor‚ its function is thought of as recreation – relaxing the worker so that he can work more efficiency after the break. When the goals are efficiency of work‚ increased production‚ more power and more wealth‚ the function of leisure

and uses of several kinds of algebraic functions. The four models include‚ linear‚ exponential‚ power‚ and inverse power. The purpose of this assignment is to review our understanding of these models and their uses and to fulfill a writing piece for the MEAP test. The first and simplest function to be discussed is the linear function. A linear function can be modeled by the equation f(x)=ax+b‚ where a is the slope and b is the y-intercept. Linear functions form a straight line when graphed and maintain

Historical Background Technology Forecasting is a product of the 20th century. Prior forecasting efforts were largely based upon the assumption and guidance of recognized experts in a given field and little more scientific thought was put into a forecast. Beginning in the 1930’s‚ a much more structured and formulated approach was placed upon the investigation‚ research‚ and predictability of future technologies. The United States Government played a critical role in emergence of technology forecasting

most accurate forecast possible so they can plan for the demands. There are forecasting tools that assist with making calculations to receive the best outcome by your company’s needs. The tools are moving average‚ weighted moving average and exponential smoothing. The moving average takes the total of actual demand for previous months then divides by the number of months added. The number of months that is used can be predefined such as using the previous three months. This is the simplest
