The answer is:
The second option,
b.)
We are given the functions E(x) and K(x), since they both are function of the same variable, we need to add them in order to find the correct option.
From the statement we know the functions:
and
So, adding the functions we have:
Hence, the answer is the second option,
b.)
Have a nice day!
Check the picture below. You can pretty much count the units off the grid.
Answer:
Step-by-step explanation:
We can use the following formula to solve this exercise:
In this case "T" is the time in hours it takes to both taps fill the pool working together, "A" is the time in hours for the first tap filling the pool alone an "B" is the time in hours for the second tap filling the pool alone.
We can identify that:
Then, we must subsitute the known values into the formula:
And finally we must solve for "B".
Then we get:
