A factory is discharging pollutants at a rate of R(t)=120 gal/day. Using enzymes and other remedies, the survival function of the pollutants in the lake is S(t)=e^-0.15t. If the lake initially contained 200 gallons of contaminants, there were contaminants in the lake, determine the level of the contaminants after 5 days

for every liter of water in a bucket there is initially dissolved 2 grams of salt. The bucket starts out with 10 liters if water. Beginning at time t=0, 5 liters of salt solution is added to the bucket every minute and 3 liter are drained every minute. The added salt solution has 3 g of salt dissolved in each liter of water. Write an initial value problem that models the rate of change of the amount of salt in the bucket with time. Do not solve the IVP
A weather balloon that contains 540 m3 of helium springs a leak and empties in 60 seconds. Suppose that the volume of helium in the balloon as a function of time is given by V (t)= 540(1-t/60)^3. Find (a) the average rate of change of volume during the 60 seconds it takes to empty. b) the volume of the balloon after 40 seconds. c) the instantaneous rate of change of the volume at 40 seconds.
Assume the rate at which the zombies spread is jointly proportional to the number of encounters between the infected and the people who are not infected yet. At the time, there are 300 students, faculty and staff on campus. When the government hears about the accident, they barricade the entire campus so no one can escape. After four hours, 20 people are infected. How many will be infected after ten hours if the T-virus started with a zombie?
We have a large tank filled with 50 liters of pure water. there is a salt solution of concentration 20 g/L flowing into the tank at a rate of 2 L/min. The well mixed solution is flowing out of the tank at a rate of 1 L/min. find the concentration of salt in the tank as a function of time. no need to worry about the tank overflowing.
Oil flows at a constant rate of 10L/min into a tank that can hold 40L of liquid. Initially the tank held 20 L of brine solution, which dissolved 2kg of salt. The solution inside the tank is kept well stirred and flows out of the tank at a rate of 8 L/min. Find the amount of salt in the tank when the tank is full.
A tank initially have 100 L with 50 g of dissolved salt. brine is pumped into the tank at a rate of 2 L/min carrying 2 grams of salt per liter. The well-stirred mixture is pumped out of the tank at a rate of 3 L/min. Find the concentration of the solution after 1 hour.
A tree farm starts with ten trees. Tree growth is expected to follow logistic growth with a first-order growth rate constant of r = 0.16 yr ' to a maximum of 8,000 trees. Write the equation that relates the number of trees (N) to time (1). What are the values of No, r, and K? Plot the number of trees over time if no harvesting occurs. Go out to about 70 years. What is the maximum sustainable yield (MSY)? How long should you wait before harvesting at the MSY? Determine the standing crop. (The standing crop is the number of trees at steady state when harvesting at the MSY.)
When drugs are administered into the bloodstream, the amount of the drug present decreases continuously at a constant rate. The amount of a certain drug, Xanaz, in the bloodstream is modeled by the function, where is the initial dosage, and t is the time (in hours) after the initial dose was given. The following chart shows the relationship between the original dose and how much is sti in the system after so much time.
