Answer:

Step-by-step explanation:
The work is define as the integral of the force times distance. So we have:

Now, we can write the force in terms of density.

V is the volume (V=2*1*1=2 m³)
So the work will be:

The limit of integration is between 0 and 0.5 because we want to pump half of the water out of the aquarium.

Answer:
x = 5.2
Step-by-step explanation:

Let's first simplify our first function:

Now, we just need to set this function equal to our other given function.

Now, we can add 12 to both sides:

Now, add 5x to both sides:

Finally, we'll divide both sides by 5:

Answer: x = 5.2
