1) 23 degrees 18 minutes

2) give me a moment

c = (1+a) *y(0) = (1+a)*76,212,170


b = if B is positive, the logistic function will always increase,
while if B is negative, the function will always decrease (not sure how to solve for it though)

a=A is the number of times that the initial population must grow to reach C

Your logistic equation's constant can easily be found by googling what logistic function is. You will see it follows a specific form and the constants all correspond to something
