one model for the spread of a rumor is that the rate of spread is proportional to the product of the fraction y of the population who have heard the rumor and the fraction who have not heard the rumor

a small town has 1000 inhabitants at 8Am , 80 people have heard a rumor by noon half the town has heard it. At what time will 90% of the population have heard the rumor?

please solve this problem meticulously with *readable* handwriting


thank you

The rate of growth of the population of rabbits in China is proportional to the current rabbit population. The population after t years is R(t). Write the differential equation for which R(t) is a solution. Your equation should involve an unknown constant Initially, there are 100 rabbits but the population is increasing at a rate of 20 per year. Use this information to find the unknown constant in part That is, write the differential equation (without an unknown constant) for...

The population of mosquitoes in a certain area increases at a rate proportional to the current population, and in the absence of other factors, the population doubles each week. There are 800,000 mosquitoes in the area initially, and predators (birds, bats, and so forth) eat 60,000 mosquitoes/day. Determine the population of mosquitoes in the area at any time. (Note that the variable t represents days.)
