 Question 112151: This question deals with an exact formula. In the following exercise use the approximate and exact formulas to find the doubling time. Also answer the given question. 38. A family of 100 termites invades your house and grows at a rate of 20% per week. How many termites will be in your house after 1 year? The approximate doubling time formula (rule of 70): for a quantity growing exponentially at a rate of P% per time period, the doubling time is approximately Tdouble = 70/P. This approximation works best for small growth rates and breaks down for growth rates over about 15%. This is the exact doubling time formula: For an exponentially growing quantity with a fractional growth rate r, the doubling time is Tdouble = log10 2/log10(1 + r). For an exponentially decaying quantity, we use a negative value for r (for example, if the decay rate is 5% per year, we set r = -0.05 per year); the half-life is Thalf= - log10 2/log10(1 + r). Note that the units of time used for T and r must be the same. For example, if the fractional growth rate is 0.05 per month, then the doubling time will also be measured in months.

 Question 112150: This question deals with the half-life formula. Use the approximate half-life formula in this exercise. Be sure to discuss whether the formula is valid for the case described. 32. A clean-up project is reducing the concenration of a pollutant in the water supply with an 8% decrease per week. What is the half-life of the concentration of the pollutant? What fraction of the original amount of the pollutant will remain when the project ends after 1 year (52 weeks)? This is the approximate half-life formula: For a quantity decaying exponentially at a rate of P% per time period, the half-life is approximately Thalf = approximately 70/P. This approximation works best for small decay rates and breaks down for decay rates about 15%. Click here to see answer by stanbon(57407)
