Answer:
<em>The maximum area of the second board must be square inches.</em>
Step-by-step explanation:
The total area of two different size boards cannot exceed square inches.
The area of one board is square inches.
Suppose, the area of the second board is square inches.
That means......
So, the maximum area of the second board must be square inches.

Step-by-step explanation:
<u>Solving Equations Using Successive Approximations</u>
We need to find the solution to the equation
where
The approximation has been already started and reached a state for x=2.5 where
The difference between the results is 0.25, we need further steps to reach a good solution (to the nearest tenth)
Let's test for x=2.4
The new difference is -0.2+0.24=0.04
It's accurate enough, thus the solution is
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.
I hope it helps you!
