Step-by-step explanation:
x=2/10 - 3/5
Divide
x + 1/5=3/5
Subtract 1/5 from both sides of the equation
x + 1/5 - 1/5= 3/5 - 1/5
x=2/5
Answer: 12 by 12 by 5 by 5
Step-by-step explanation: 12*5 = 60
12+12+5+5
=34
Answer:
The answer is below
Step-by-step explanation:
The total revenue from the sale of a popular book is approximated by the rational R(x) = 1100x^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}
Solution:
Revenue is the total money made from the selling of a product or item.
a) Given the revenue function:

At the end of the first year (i.e. x = 1), the venue is given as:

b) At the end of the second year (i.e. x = 2), the venue is given as:

c) The domain of the function is the value of the denominator for which the value of the denominator is not zero
x² + 4 ≠ 0
The domain is {x| x is a real number and x ≥ 0}
So one trip = 4 km
two trips = 8
8 + 4 = 12
i believe your answer is 12
Thanks!
Answer:
If x=1, then f(x)= undefined
Step-by-step explanation:
1*1=1
1-1=0
0/0
You can't divide by 0, so anything that is divided by 0 is undefined.
((1*1)-1)/(1-1)
(1-1)/(1-1)
0/0
0/0=Undefined
f(x)= undefined
