No, a function can only have one variable.
Answer:
55 gallons
Step-by-step explanation:
Given that the diameter of the cylindrical barrel is 22 inches, so the radius of the barrel is 
And height of the cylindrical barrel is 33.5 inches.
So the volume of oil in the cylindrical barrel is

Also given that there are 231 cubic inches in a liquid gallon, so to find the number of gallons of oil in barrel, we use unitary method.
231 cubic inches goes in = 1 gallon
1 cubic inches will go in 

Answer: The expected population in 25 years should be approximately 4,374
Step-by-step explanation:
Answer:
16.42 years
Step-by-step explanation:
Use the Future value formula; FV = PV (1+r)^t
PV= Initial amount deposited, 500
r= interest rate or discount rate, 2.5%
t = total duration of the investment, ?
FV= future value of account, 750
Plug in the numbers into the formula
750 = 500* (1+0.025)^t
divide both sides by 500
750/500 = 1.025^t
put ln on both sides
ln 1.5 = ln
ln 1.5 = t ln 1.025
0.4054651 = 0.0246926 t
Divide both sides by 0.0246926
0.4054651/0.0246926 = t
t = 16.42
16.42 years
The answer is 4.................
