Atleast one of the answers above is NOT correct 1 of the questions remains unanswered in 1940, there were about 10 brown tree snakes per square mile on the island of guam, and in 1995, there were about 5000 per square mile (a)Find an exponential formula for the number, N| of brown tree snakes per square mile on guam t|years after 1940

Solution

general exponentiatal equation is N=N_oe^rt

in 1940, t=0

10=N_oe⁰

N_o=10

N=10e^rt

in year 1995, t =1995-1940 =55

5000=10*e^r*55

e^r*55=500

55r =ln(500)

r=(ln500)/55

r=0.11299287

r=0.113

N=10e^0.113t is the exponential formula

b)r=0.113

r=11.30%

annual percent increase in population is 11.30%
