- Medical research indicates that the risk of having a car accident increasesexponentially as the concentration of alcohol in the blood increases. The risk is modeled by R = 6e12.77x, where x is the blood alcohol concentration and R, given as a percent, is the risk of having a car accident. What blood alcohol concentration corresponds to a 17% risk of a car accident? How is this shown on the graph of R in the herewith given Figure?During a snowstorm, snow fell at a constant rate for a number of hours. Then it stopped snowing for a number of hours. Then it started up again at a different constant rate. Addison made a graph showing the inches of snow on the ground over time using the data that she collected. At what rate was the snow falling during the second snowfall?Suppose that a vending machine service company models its income by assuming that money flows continuously into the machines, with the annual rate of flow given by f(t) = 110e0.02t in thousands of dollars per year.

- A police car traveling south toward Sioux Falls, Iowa, at 160km/h pursues a truck traveling east away from Sioux Falls at 140km/h. At time t=0, the police car is 40km north and the truck is 30km east of Sioux Falls. Calculate the rate at which the distance between the vehicles is changing at t= 0 minutesThe population of a city, in millions, since 1990 has grown at a rate of P′(t)=0.21e^ 0.027t million people per year, where t is the number of years after 1990. If there were 1.5 million people in 2000, estimate (to two decimalplaces) the population in 2004.A two-day environmental clean up started at 9AM on the first day. The number of workers fluctuated as shown in the following figure. Suppose that the workers were paid 12 dollars per hour for work during the time period 9 am to 5 pm and were paid 18 dollars per hour for work during the rest of the day. What would the total personnel costs of the clean up have been under these conditions?
