Answer:
On a graphing table, f(x) is y.
Step-by-step explanation:
Lets say, for ease, that the vat can hold a total of 70 gallons (or whatever you would like to use.) Use whatever number you want, I just picked this because it gives us a lot of clean numbers.
Now, if the inlet can fill it in 7 hours, that means that it is adding 10 gallons per hour. (70 gal/7 hours = 10 gal/hr)
For the outlet, use the same process, and you find that it drains the vat at 7 gallons per hour.
So, if you subtract the outlet from the inlet, you get 10 - 7 = 3 gallons per hour added.
Now just divide the size of the vat by that number, and you find your answer.
70 gallons / 3 gallons per hour = 23 1/3 hours.
The correct answer is option E. which is the product will be 13.86594.
<h3>What is the product?</h3>
Multiplication is the process of determining the product of two or more numbers in mathematics. Given numbers are 3.278 and 4.23.
The product of the two numbers will be calculated as:-
P = 3.278 x 4.23
P = 13.86594.
Therefore the correct answer is option E. which is the product will be 13.86594.
