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+5553 X 98,000 deaths in what year?
Answer provided by our tutors
year should be after 1984
D(X) = 240(2)^1/2 + 5553x = 98000
solve for x
x =35.2351
this means that it is 35.2 years after 1984
1984+35.2= 2019 --> it is the year 2019
