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.
Answer:
3 cups
Step-by-step explanation:
Assumptions: How much sugar does cost sprinkle on the brownies. Cost meant Cody
Given data:
Total of 4 cups
3/4 is sprinkled onto a plate of brownies
The rest onto a plate of lemon cookies
<em>Sugar sprinkled on brownies </em>= (3/4) * 4
<em>Sugar sprinkled on brownies</em> = 3 cups.
To answer this question we can propose the following equation:
Where:
x is the number of weeks elapsed.
d is the debt depending on the weeks.
Robert promised to pay at least $ 67 each week.
Therefore, after 5 weeks the debt of rober should be:
Then scenario A) is possible because .
After 6 weeks:
Then scenario B) is possible because .
After 7 weeks
Then scenario C) is possible because .
After 8 weeks
So scenario D) is NOT possible because
Finally the correct answer is option D.
The answer would be 7776^2 / 343^2 written as a fraction OR about 513.95402 written as a decimal.
