Determine whether or not F is a conservative vector field. If it is, find a function f such that F = ∇f. (If the vector field is
snow_tiger [21]

If

\nabla f=(xy\cos xy+\sin xy)\,\vec\imath+x^2\cos xy\,\vec\jmath

then we should have

\dfrac{\partial f}{\partial y}=x^2\cos xy\implies f(x,y)=x\sin xy+g(x)

Differentiating with respect to x gives

\dfrac{\partial f}{\partial x}=xy\cos xy+\sin xy=\sin xy+xy\cos xy+g'(x)

\implies g'(x)=0\implies g(x)=C

So F is indeed conservative, and

f(x,y)=x\sin xy+C

Answer:

x = 5 pens

y = 7 pencils

Step-by-step explanation:

let

x = the number of pens

y = the number of pencils

Anthony spent $2.80 to buy a total of 12 pens and pencils

0.35x + 0.15y = 2.80

x + y = 12

by solving the system of equations

0.35x + 0.15y = 2.80

x + y = 12

we find

x = 5 pens

y = 7 pencils
