Answer:
Step-by-step explanation:
The given function is
and the inverse function is
To find f(2), we substitute x=2 into the function f(x)=½x
This implies that,
Similarly,
Based on the above results,
Answer:
Read answer below :)
Step-by-step explanation:
So you know that it takes 90 seconds for 10 gallons, right? So you know it's 9 seconds per gallon, removing the 0's (which is the easiest way to simplify).
then you take 8 divided by 60 to find out how long it takes for one gallon.
My math shows this:
A = 9 seconds per 1 gallon
B = 7.5 seconds per 1 gallon
60 seconds for 8 gallons, 30 seconds for 4 gallons, 15 seconds for 2 gallons, 7.5 seconds for 1 gallon. (Notice how I divided by two each time until it was simplified)
