Consider three connected lakes, A, B, and C, where lake B has a volume of 2650 km, and water flows from lake A into lake B, andfrom lake B into lake C, both inflows and outflows at the same rate of 525 km/year. Suppose that at time t=0 (years), the pollutantconcentration of lake B, caused by past industrial pollution that has now been ordered to cease, is five times that of lake A. If theoutflow from lake B to lake Cis perfectly mixed lake water, how long will it take to reduce the pollution concentration in lake B totwice that of lake A? (Choose all correct answers)Less than eight years.B) More than 11 years.Less than six years.More than five years.

The population of an island from 1970 to 2020 is modeled by the logistic function: P(t)= 150,000/1+5e^-.124t where t is the number of years that have passed since 1970. A.) find the exact population of the island in 1970 and 2020 B.) given that the logistic growth model will also be valid in the future, write down the largest possible population that the island will ever be able to accommodate C.) find the number of years it took for the population of the island to reach 100,000
Suppose a species of fish in a particular lake has a population that is modeled bythe logistic population model with growth rate k, carrying capacity N, and time tmeasured in years. Adjust the model to account for each of the following situations. * One hundred fish are harvested each year.* One-third of the fish population is harvested annually.* The number of fish harvested each year is proportional to the square root of thenumber of fish in the lake. I was hoping to compare my answer to yours because I am a little confused if I did it right. Thank you for your time and effort.
The population of a bacteria increases at a rate proportional to the present number of bacteria ‘P0’ equal to 3000. If its present population becomes double in 2 hours, how long will it take that its population becomes ‘2’ times?
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.)
A certain radioactive material is known to decay at a rate proportional to the amount present. If initially there are100 milligrams of the material present and if after two years it is observed that 5 percent of the original mass has decayed, find (a) an expression for the mass at any time t and (b) the time necessary for 10 percent of the original mass to have decayed.
