Answer:
Part 1: or
Part 2:
Step-by-step explanation:
To start things off, you must put everything on the opposite side of y so that you only have the y variable left.
In this case, put x onto the other side, making it negative since it's flipped, so you get (since the x is negative you're using subtraction from 11).
Next, divide both sides by 5 to make 5y into y:
Then in this case you turn y=f(x), but the system did it for you, so all you have to put is .
For the second part you must replace x with 2 since you need to find f(2).
Your answer for part 2 is .
Answer:
The cost of wasted nitric acid is $187.02
Step-by-step explanation:
Since it is given that specific gravity of Nitric Acid is 1.42 Thus the density of nitric acid is
Now from the basic relation of mass volume and density we have
Since the mass of the nitric acid is given to be 5.112 kg = 5112 grams
Thus the volume of nitric acid is
Now we know that 1000 cubic centimeters euals 1 litrer
Thus the calculated volume in liters is
Thus the cost of acid spilled equals
