<span>We want to show that f(g(x)) = x and g(f(x)) = x.
So to do that, we need to calculate f(g(x)) and g(f(x)) explicitly.
Let's begin with f(g(x))
Now, f(g(x)) = f(4/x), by definition of g, as g(x) = 4/x
What then is f(4/x) equal to? Use the definition of f.</span>
Answer:
A. 35
Step-by-step explanation:
Each week has 7 days, and we have 5 weeks.
Week 1 has 7 days.
Week 2 has 7 days.
Week 3 has 7 days.
Week 4 has 7 days.
Week 5 has 7 days.
We can add all these together to get the total number of days: 7 + 7 + 7 + 7 + 7 = 7 * 5 = 35.
Thus, the answer is A.
Hope this helps!
Answer:
Therefore the company made 510 liters of Drink A and (510+80)=590 liters of Drink B.
Step-by-step explanation:
Let, the company make x liters of drink A
The company makes drink B of (80+x) liter. Since the company make 80 more liters of Drink B than liters Drink A .
Given drink A contains 20% real fruit.
Therefore x liters of drink A contains
liters
liters real fruit.
Drink B contains 5% real fruit juice.
(80+x) liters of drink B contains
liters
liter real fruit.
The company used 56.5 liters of real fruit juice to make Drink A and Drink B.
According to the problem,


⇒80+5x = 56.5×20
⇒80+5x=1130
⇒5x=1130-80
⇒5x=1050

⇒x=510
Therefore the company made 510 liters of Drink A and (510+80)=590 liters of Drink B.
