1:40.
1:40 is equal to 1/40, while 1:60 is equal to 1/60.
1/40 is the bigger fraction, so 1:40 is the correct answer.
Answer:
d.x=-8 and x=-10
Step-by-step explanation:
SInce the 'growth factor' is 1.32, the 'growth rate' is .32 or 32%
0.1111 if you want it as a decimal
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.
