Colleen Cooper Solving Quadratic Equations MAT 126 Survey of Mathematical Methods Instructor: Kussiy Alyass October 1‚‚ 2012 Solving Quadratic Equations Using correct methods to solve quadratic equations can make math an interesting task. In the paper below I will square the coefficient of the x term‚ yield composite numbers‚ move a constant term and see if prime numbers occur. I will use the text and the correct formulas to create the proper solutions of the two projects that are

Exponential growth shows a “J shaped” curve because with each generation‚ the number of organisms producing offspring increases‚ resulting in a rapid increase in population size. 4a. A logistic growth curve has an S-shape. 4b. When a population’s growth slows following a period of exponential growth and then stops at or near the carrying capacity. 4c.

from the graph that the four-week moving average forecast smoothes the data the most‚ while the naïve forecast responds to change the best. (1 mark) 4.5 Given the following data‚ use exponential smoothing ( = 0.2) to develop a demand forecast. Assume the forecast for the initial period is 5. Exponential Smoothing Forecast Ft = Ft-1 + (At-1 – Ft-1) ie F2 = F1 + (A1 – F1) = 5 + 0.2 (7 – 5) = 5.4. Carrying this through to week 7 gives: Period Demand Exponentially Smoothed Forecast 1

Complex Numbers and Applications ME50 ADVANCED ENGINEERING MATHEMATICS 1 Complex Numbers √ A complex number is an ordered pair (x‚ y) of real numbers x and y. For example‚ (−2.1‚ 3.5)‚ (π‚ 2)‚ (0‚ 0) are complex numbers. Let z = (x‚ y) be a complex number. The real part of z‚ denoted by Re z‚ is the real number x. The imaginary part of z‚ denoted by Im z‚ is the real number y. Re z = x Im z = y Two complex numbers z1 = (a1‚ b1) and z2 = (a2‚ b2) are equal‚ written z1 = z2 or (a1‚ b1) = (a2‚ b2)

What is the difference between a condition and a resource? Be able to categorize particular environmental factors as conditions OR resources (for example‚ temperature is a condition and not a resource).

software that was used in order to predict the future sales was StatTools. StatTools provided me with four different methods (Moving Averages‚ Simple‚ Holt’s & Winters’ exponential smoothing) of forecasting to identify the most accurate prediction possible. With a Means Absolute Percentage Error (MAPE) of 3.72% the Holt’s exponential smoothing method was determined to be the best method of predicting monthly wine sales for the next sixteen months (Figure 2).
