spread of a direct contact disease in a stadium is modeled by the exponential equation P(t) = 10‚000/(1 + e3-t) where P(t) is the total number of people infected after t hours. (Use the estimate for e (2.718) or the graphing calculator for e in your calculations.) 1. Estimate the initial number of people infected with the disease. Show how you found your answer. Answer: A total of 474 people would be initially infected. Equation: p(0)=10‚000/(1+3^3) ~ 474.26 2. Assuming the disease

fairly slowly‚ as they are preparing for the rapid division (Doyle). In this lag phase the bacteria is making fats and proteins which will jump-start the log phase (Doyle). The next phase in the bacteria ’s life cycle is the log (logarithmic or exponential) phase. At this point‚ the bacteria begin replicating swiftly. Once the culture reaches high densities‚ their living space and nutrients begin to deplete‚ and the toxicity levels begin to increase (Doyle). Due to this rapid growth‚ the next

Equations of Motion In the absence of air resistance: where: s = the position at time t s0 = the position at time t = 0 v0 = the speed at time t = 0 g = the acceleration due to gravity. When there is air resistance‚ it is characterised by a constant : Then the equation of motion is approximately: The Apparatus The precision of the metal scale is one part in 4000. The accuracy

suitable technique to generate the forecast of unemployment rate using data from the series of Labour Force Surveys. The models understudied are based on Univariate Modelling Techniques i.e. Naïve with Trend Model‚ Average Change Model‚ Double Exponential Smoothing and Holt’s Method Model. These models are normally used to determine the short-term forecasts (one quarter ahead) by analyzing the pattern such as quarterly unemployment rates. The performances of the models are validated by retaining

can use the substitution method to set both equations equal to each other. 5x = 185 5/5 = 185/5 x = 37 Plug x = 37 back into one of the equations above to find y. y = 5 * 37 y= 185 The solution point is 37 hours for $185‚ (37‚$185) Daycare option y = 5x Center based option y = 185 + 8(x-40) (for x > 40 hours) Since they are both equal to y‚ we can use the substitution method to set both equations equal to each other. 5x = 185 + 8(x-40)
