One model for the way diseases die out when properly treated assumes that the rate dtdy at which the number of infected people changes is proportional to the number y. The number of people cured is proportional to the number that have the disease. Suppose that in any given year, the number of cases of a disease is reduced by 22%. There are 10,000 cases today. a. How long will it take to reduce the number of cases to 1000 ? b. How long will it take to eradicate the disease, that is, reduce the number of cases to less than 1 ? It will take years to reduce the number of cases to 1000 (Round to the nearest hundredth.)
Solve the differential equation. 5xydxdy=1,x,y>0
The halt-ife of plutonium-239 is 24,360 years. If 15 g of plutonium is released into the atmosphere by a nuclear accident, how many years will it take for 74% of the isotope to decay? It will take years for 74% of the isotope to decay (Do not round until the final answer Then round to the nearest year as needed)
