Problema Solution
the function d(x) models the cumulative number of deaths from a disease x years after 1984
estimate the year when there was 98,000 deaths
d(x)=2450sqrt2 + 5553x+ 5270
approximately 98,000 deaths in what year?
Answer provided by our tutors
year should be after 1984
D(X) = 2450(2)^1/2 + 5553x = 98000
solve for x
x =17.0242
this means that it is 17 years after 1984
1984+17= 2019 --> it is the year 2001
