1. In a research experiment, a population of fruit flies is increasing according to the law of exponential growth. After 2 days there are 100 flies, and after 4 days there are 300 flies. How many flies will there be after 5 days?

 

2. A conservation organization releases 100 animals of an endangered species into a game preserve. The organization believes that the preserve has a carrying capacity of 800 animals and that the growth of the herd will follow the logistic curve p(t)=(800)/1+10e^-0.1656t , where t is measured in months. a. What is the population after 5 months? Round to nearest animal. b. When will the herd reach 50% of the preserve's carrying capacity? Round to the nearest month. 

 

3. The level of sound B, in decibels, with an intensity I is B=10log(with subscript 10) * (I)/(I)subscript 0. where I (subscript 0) is an intensity of 10^-12 watt per square meter, corresponding roughly to the faintest sound that can be heard by the human ear. With this information, solve the following problem. Due to the installation of a muffler, the noise level of an engine was reduced from 88 to 72 decibels. Find the percent decrease in the intensity level of the noise as a result of the installation of the muffler.
