Answer:
f(2b) = 4b^2 +4b +1
Step-by-step explanation:
Put 2b where x is and simplify.
f(2b) = (2b)^2 +2(2b) +1
f(2b) = 4b^2 +4b + 1

Answer:
4 months
Step-by-step explanation:
(2000 *6)/100 = 120
120x = 480
X = 480/120
X = 4 months
We have that if we assume standard exponential growth, the equation of the population will be:

if we start counting from the moment that the population was 7000. We are given that 7000*

=12000, namely that P(5)=12000 and we need to find

. Since e^(10k)=e^(5k)*e^(5k), and since we can solve for e^(5k) from P(5), we have:
e^(5k)=12000/7000 and we can calculate P(10). P(10)=7000

= 20571 people.
