Answer:
Third option i.e. A. and B. About 4,323 people
Step-by-step explanation:
We are given that,
Initial population of the town = 2,700
The rate of growth = 4% = 0.04
Part A: Since, the equation for the growth is given by,
Population growth = , where P is the initial population, r is the rate of growth and x is the time period of growth.
We have, according to the question,
Population growth =
i.e. Population growth =
Thus, the equation for the population growth is .
Part B: Now, it is required to find the population after 12 years i.e. x= 12.
So, we have,
Population =
i.e. Population =
i.e. Population =
i.e. Population = 4,323
Hence, the population after 12 years is 4,323 people.
Thus, the third option is correct.
We can set this problem up as an algebraic equation, which we can then solve to find our answer.
We start at -3. So we can start our equation with that:
However, this doesn't represent any change in temperature, just that we start at -3. To show change, we will use the variable , where
stands for the number of hours. Each hour accounts for a change of -2.5 in degrees, meaning that we must multiply our
by -2.5. We can now add this term into our equation:
We are trying to find when we will reach -18 degrees, so we will set our entire equation equal to -18 and solve:
It will take us 6 hours, or choice A.
