Answer:
part A) see the explanation
part B) The population in 25 years since 1970 will be one million seven hundred thousand people (1,700,000)
Step-by-step explanation:
<u><em>The correct equation is </em></u>
Part A) what are t values when it is 1985 and 1990.
we have
This is the linear equation in slope intercept form
where
P(t) ----> is the population, in thousands
t ----> the time, in years, since 1970
Remember that
t = 0 for 1970
so
For the year 1985
For the year 1990
Part B) what is p(t), when t=25?
For t=25 years
substitute the value of t in the linear equation
Remember that the population is in thousands
That means
The population in 25 years since 1970 will be one million seven hundred thousand people (1,700,000)
