Get college assignment help at uniessay writers While we do have multiple methods for solving systems of equations, its really a matter of choice on our part. Either way will work, although one is usually neater and faster than another. How can I create a system of equations problem and solve it using elimination and substitution? Examples please.

## A particle starts at the point (-3, 0), moves along the

A particle starts at the point (-3, 0), moves along the x-axis to (3, 0), and then along the semicircle y = √9 – x2 to the starting point. Use Green’s Theorem to find the work done on this particle by the force field F(x, y) = ‹3x, x3 3xy2›.

## Coffee is being poured into the mug shown in the figure

Coffee is being poured into the mug shown in the figure at a constant rate (measured in volume per unit time). Sketch a rough graph of the depth of the coffee in the mug as a function of time. Account for the shape of the graph in terms of concavity. What is the significance of the inflection point?

## Water is leaking out of an inverted conical tank at a

Water is leaking out of an inverted conical tank at a rate of 4500 cm3/min at the same time that water is being pumped into the tank at a constant rate.
