A forest fire is burning down a narrow valley 3 miles wide at a speed of 40 feet per minute. The fire can be contained by cutting a firebreak through the forest across the valley. It takes 30 seconds for one person to clear one foot of the firebreak. The value of lost timber is $4,000 per square mile. Each person hired is paid
If an object is thrown upward from 15 meters above ground with an initial velocity of 18 meters per second, then its height h above ground after t seconds after it is thrown is given by h(t)=-4.9t²+18t+15 Use your calculator to answer the following (round to the nearest hundredth, if necessary): a) Ske
Let f be continuous on a closed bounded region R and let it be analytic, and not constant throughout the interior of R. Assuming f(z) is not equal to 0 inside R (this assumption is easy since we may add a finitely large constant to f to avoid having it touch 0. Prove that |f(z)| has a minimum value m in R, which occurs on the bo
Data collected on the yearly demand for 50-pound bags of fertilizer at Wallace Garden Supply are shown in the following table. Develop a 3-year moving average to forecast sales. Then estimate demand again with a weighted moving average in which sales in the most recent year are given a weight of 2 and sales in the other 2
Sales of Cool-Man air conditioners have grown steadily during the past 5 years: The sales manager had predicted, before the business started, that year 1's sales would be 410 air conditioners. Using exponential smoothing with a weight of Coefficient = 0.30, develop forecasts for years 2 through 6. YEAR SALES
