If f(x, y)= xe2y +y, evaluate grad f •dr where C is the straight line joining the point (2,0) to the point (3,0). (A) -1 (B) -3 (C) 1 (D) 0 (E) -2

Find the equation of the linear function f(x), that has a slope of -2 and passes through the point (5, 1).

,2,,2 Suppose that f(x, y) = 10x²y² + 6x? + 2y? then find the discriminant of f.

A company decides to change its floor plan from cubicle to open office. This will bring in a constant stream of $1,000 in extra income annually. If the company invests this extra income in an account that earns 2.5% continuously compounded interest for ten years, is it worth the change? The change in floor plan costs $7,000.
