Answer:
The answer is 90;
Step-by-step explanation:
since each variable has a given value, just plug the numbers into the equation.
3(6)5=90
Since there is no d in the equation, don't worry about it:)
Answer:
(16-7)x4
Step-by-step explanation:
You put 16-7 in parenthesis so it means to do it first, then multiply by 4.
(b) Explain why the change in population from 1960to 1970 is not the same as the change in population from 1980 to 1990.
(c) Use the model to estimate the population in 2020.
Answer:
the answer is below
Step-by-step explanation:
The model is:
where t is the time in years.
a)
b)
The change in population from 1960to 1970 is 111071-70751 =40320
The change in population from 1980 to 1990 is 273737-174368=99369
The change from 1960to 1970 is not the same as the change from 1980 to 1990 because the model function is not linear, it is exponential. Therefore, the rate of the change is not constant.
c)
The population in 2020 using the model can be estimated as
when t=60 (year 2020)
