The total revenue from the sale of a popular book is approximated by the rational R(x) = 1000x^2/x^2 + 4, where x is the number of years since publication and the total revenue in millions of dollars. Use this function to complete parts a through d. (a) Find the total revenue at the end of the first year. $ million (b) Find the total revenue at the end of the second year. $ million (c) Find the domain of function R. Choose the correct domain below. {x | x is a real number and x greaterthanorequalto 0} {x | x is a real number and x lessthanorequalto 5} {x | x is a real number and x notequalto 2, x notequalto 5} {x | x is a real number and x notequalto 2}

a) 200 million dollars

b) 500 million dollars

c) Option A)

Step-by-step explanation:

We are given the following in the question:

where R(x) is the revenue function in millions of dollars and x is the number of years since publication.

a) total revenue at the end of the first year

We put x = 1 in the revenue function

Thus, the revenue after 1 year is 200 million dollars.

b)  total revenue at the end of the second year

We put x = 2 in the revenue function

Thus, the revenue after 2 year is 500 million dollars.

c)  domain of function R

Domain:

It is the values of x for which the function R(x) is defined.

Since,

Thus, it is a proper function.

The domain is given by

Option A)

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
