There were 230600 jobs available in the field of radiology in the year 2014. Each year, that number is expected to grow by 0.9%. Write a function that gives the expected number j(t) of jobs in radiology t years from the year 2014
Answer:
The function model that gives the expected number of jobs in radiology for a number of years from 2014 is .
Further Explanation
Though Simple Interest formula, in business mathematics, deals with money problem, the same formula can also be used to different aspects which deal with similar behavior. A particular amount that is increasing as the year passes by.
The formula for simple interest is given by the equation ,
where is the future value for a specific number of years,
is the principal value or the initial value,
is the increase rate (usually in percentage), and
is the time in years
Steps in Deriving of Formula
1. t still stands for the time in years.
2. r still stands for the increase rate.
3. P still stands for the principal value.
This time we are not going to interpret the formula as a money problem but we are going to use it as a population problem.
Now substitute the values of and
into the formula.
So the function that gives the expected number of jobs in radiology t years from the year 2014 is .
Lets say for example, how many jobs available in the field of radiology in the year 2016?
This means that we are looking at 2 years after. So our time, , is 2.
To solve the example, substitute into the function model, then simplify.
This means that after two years, there are approximately 234, 751 jobs available in the field of radiology from 2014.
