Answer:
This means that the correct initial value problem for the population p(t) as a function of time is is
Step-by-step explanation:
The population of a town increases at a rate proportional to its population:
This means that this situation is modeled by the following differential equation:
In which k is the growth rate.
By separation of variables, the solution is given by:
In which P(0) is the initial population.
Initial population of 1000.
This means that the correct initial value problem for the population p(t) as a function of time is is
If you put the equation into graphing calculator online or manual, you can get the graph.
Option c : 9 is the answer.
Explanation:
The expression is
We need to determine the subtracted value of the expression.
From the expression we can see that the expression contains two negative signs.
To simplify the expression, we know that, When we multiply two negative numbers then the product is always positive.
This means
Thus, the expression can be written as
Adding the two numbers, we get,
Thus, the value of the expression is 9.
Hence, Option c is the correct answer.
