n The graph is concave up before the inflection point, and concave down after the inflection point. Question 2 Your answer is INCORRECT. Given the logistic growth model 400 1 + be-0.0052t Find b, given that the initial population is 70. Round the value of b to the nearest hundredth a) 6.71 b) 5.80 c) 5.63 d) 4.71 e) 4 74

Solution

N(t) = 400 / ( 1 + be^-0.0052t )

initial population is when t = 0

400 / ( 1 + be^-0.0052t(0))

70 = 400 / ( 1 + b)

70 (1+b) = 400

70 + 70b = 400

70b = 330

b = 4.714

option d is correct
