A species of frog on an island initially had a population of 425 when scientists first began studying it. Since then, the population has increased 6.5% each year. Model this situation where f(x) is the number of years since the scientists began studying the population?

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

B? ? i'm most likely wrong but i think it would be b

(1/x + 1)^2 + 6 (1/x + 1) +5
