Question 23355: i am being asked to explain the mathematical modeling for the following:
A deer population increases from 140 in 1990 to 365 in 1995.
a) what is the growth rate for the 5 year period?
b) write an equation describing the deer population in terms of the number of 5 year periods?
c) What is the annual growth factor?
d) write an equation describing the deer population in terms of 1 year periods?
e) How can I modify my equation so that the equation used to describe the 5 year population utilizes the annual growth factor?

You can put this solution on YOUR website!
a) for 5 years the growth rate is 365-140= 225/per 5 years
b) Let "d" be number of deer; Let "t" represent 5 yr. periods
d=225t
c) annual growth rate = 225/5 = 45 deer/year
Let "d" be number of deer; Let "t" represent 1 yr. periods
d) d=45t
e) d=(1/5)225 (t/5)
