Given that,
An expression : 
To find,
The value of the above expression when e = 12 and f = 1/2
Solution,
We have,

Put e = 12 and f = 1/2
So,

So, the value of the above expression is 1.
Answer:
take the total cost and multiply it with 0.8 (80% of 100%) and thats your answer
Step-by-step explanation:
Answer:
Step-by-step explanation:
Factor it by first setting it equal to 0:
Now subtract 9 from both sides:
Divide both sides by 4:
Then take the square root of both sides:
x = ±
, which of course is not allowed. Therefore, we have to allow for the imaginary numbers in this solution. Knowing that,
x = ±
is an equivalent radicand, we can now replace -1 with its imaginary counterpart:
x = ±
Each one of the elements in the radicand are perfect squares, so we simplify as follows:
x = ±
And there you go!
Answer:
Its 180!
