Answer:
24.1 billion
Step-by-step explanation:
One way to write the logistic function is ...
P(t) = AB/(A +(B-A)e^(-kt))
where A is initial value (P(0)), and B is the carrying capacity (P(∞)). We are told to use relative population growth in the 1990s as the value for k.
In billions, we have ...
A = 5.3
B = 100
k = 0.02/5.3 ≈ 0.003774 . . . . . relative growth rate at 20 M per year
t = 2450 -1990 = 460

Answer:
(1)
Step-by-step explanation:
1. the y-intercept is at positive 4
2.y will be more than -3x+4 because of -3 if it was a positive y would be less
Answer:
A
Step-by-step explanation:
Khan gives you right answer and tells you what's wrong, but this site is for help so, all you need to do is use the destructive property.
12 x 2= 24 12 x 3 = 36 12 x -1 = -12
now you have the original expression, 24 + 36 - 12 (without the letters.)
I believe the second one right, because if I remember two opposite angles of an outside angle = the outside angle.
