The number of endangered animal species in the US from 1990 to 2002 can be modeled by

Y = -119 + 164ln t , 10 ≤ t ≤ 22

Where t represent the year, with t = 10 corresponding to 1990. During which year did the number of endangered animal species reach 357?



2 pt

The number y of hits a new search engine website receives each month can be modeled by y = 4080 ekt where t represents the number of months the website has been operating. In the websites’s third month, there were 10,000 hits. Find the value of k, and use this result to predict the number of hits the website will receive after 24 months.


2 pt

What is k = 0.2988 which is appox. 5,309,734 hits? each month can be modeled by y = 4080 e
