Are you talking about the displacment needed to lift 3000 pounds in water? The total displacment would need to equal the weight of the object AND the contianment vessel AND the entrapped air. Water weighs about 8 (fuel is 6) pounds per gallon. So you'd have to divide the total weight of all objects by 8 pounds to find the displacment. Recognize that you can also count the displacment of the object being lifted as part of the total displacment, so if the 3000 pound object displaces 100 gallons of water, that reduces the total additional displacent by 100 gallons.
A formula is a statement. It's not a problem or an exercise to which a solution is needed.
A formula is needed to find the area of a parallelogram. It is a very simple formula which notates Area = base x height.
Sorry, but more information is needed to answer this question. There are hundreds, if not thousands, of formulas, each of which has a different solution. If you append to this answer the formula you are asking about, I could help you.
More information is needed to determine x and y. Do you have a point on a graph? Are you given a formula?
The mid-point is needed when the perpendicular bisector equation of a straight line is required. The distance formula is used when the length of a line is required.
To work out the density of a pebble the equipment you need are the following : -A Displacement Can -A Beaker -A Weighing/measuring scale

The required velocity is the given displacement/the given time intervalin the direction from the starting point to the end point.

Because the centrifugal pump cannot pump air due to its loose tolerances, the positive displacement pump is needed to create the vacuum.
The force. Work=force x displacement Displacement=100m Work=? <----------------- if it's work your trying to find you need to force=? Know force and displacement. You know the Displacment, so force is missing.
In order to measure velocity you need displacement (a start location and an end location) and time.
