Answer:
20,158 cases
Step-by-step explanation:
Let represent year 2010.
We have been given that since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year.
Since the flu cases decrease to 85% of the prior year, so the flu cases for every next year will be 85% of last year and decay rate is 15%.
We can represent this information in an exponential decay function as:
To find number of cases in 2020, we will substitute in our decay function as:
Therefore, 20,158 cases will be reported in 2020.
width = 10 feet → C
let l represent the length then width = l - 8
perimeter = 2(length + width) = 2(l + l - 8)
given perimeter = 56 then
2(2l - 8)= 56
divide both sides by 2
2l - 8 = = 28
add 8 to both sides
2l = 28 + 8 = 36
divide both sides by 2
l = = 18
thus length = 18 feet and width = 18 - 8 = 10 feet
