Using data from 2002 and with projections to 2024, total annual expenditures for national health care (in billions of dollars) can be described by E = 4.61x2 + 43.4x + 1620 where x is the number of years past 2000.† If the pattern indicated by the model remains valid, in what year does the model predict these expenditures will reach $15,315 billion?

In 2050, the predicted expenditure will be $15,315 billion.                  

Step-by-step explanation:

We are given the following in the question:

where E(X) is the total annual expenditure in billions of dollar and x is the number of years past 2000.

We have to estimate the year in which predicted expenditure will be $15,315 billion.

Putting values in the question:

Thus, after 50 years from 2000, the predicted expenditure will be $15,315 billion.

Thus, in year 2050, the predicted expenditure will be $15,315 billion.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !
