Answer:
P(t) = 27000 * (1/9)^(t/4)
Step-by-step explanation:
This problem can me modelled with an exponencial formula:
P = Po * (1+r)^t
Where P is the final value, Po is the inicial value, r is the rate and t is the amount of time.
In this problem, we have that the inicial population/value is 27000, the rate is -8/9 (negative because the population decays), and the time t is in months, so as the rate is for every 4 months, we use the value (t/4) in the exponencial.
So, our function will be:
P(t) = 27000 * (1-8/9)^(t/4)
P(t) = 27000 * (1/9)^(t/4)
Answer:
the answer is c
Step-by-step explanation:
i just did it
50 years ... 2.5 degrees
1 year ... x degrees = ?
If you would like to know what is the rate of change in worldwide temperatures per year, you can calculate this using the following steps:
50 * x = 2.5 * 1
50 * x = 2.5 /50
x = 2.5 / 50
x = 0.05 degrees per year
Result: The rate of change is 0.05 degrees per year.
