<PRE><B>Question 401635</B>
 The population of a certain species of deer can be modeled by the funtion p=30.000+20.000cos( pi/10(t)),where p is the population and t is the time in years 
1) What is the amplitude of the population and what does it represent?
---
Amp = 20,000 represents the highest variation in the deer population.
-----------------------------
2) What is the period of the function and what does it represent?
Period = (2pi)/(pi/10) = 20
reprsents the time in years between peak population numbers.
