Determine whether or not the vector field is conservative. if it is, find a function f such that f = ∇f. if the vector field is

amm1812

$\dfrac{\partial f}{\partial x}=3y^2z^3\implies f(x,y,z)=3xy^2z^3+g(y,z)$

$\dfrac{\partial f}{\partial y}=6xyz^3+\dfrac{\partial g}{\partial y}=6xyz^3$
$\implies\dfrac{\partial g}{\partial y}=0\implies g(y,z)=h(z)$

$\dfrac{\partial f}{\partial z}=9xy^2z^2+\dfrac{\mathrm dh}{\mathrm dz}=9xy^2z^2$
$\implies\dfrac{\mathrm dh}{\mathrm dz}=0\implies h(z)=C$

$\implies f(x,y,z)=3xy^2z^3+C$

The potential function exists, so $\mathbf f$ is indeed conservative.

PLS HELP I WILL MARK BRAINLIEST (EDITED)

Vinvika [58]

Answer:

51.9

Step-by-step explanation:

because one side is 30 and another is 60, you can assume the 3rd side of the triangle is 51.9 because of the 30-60-90 rule which states that if each angle of a triangle is 30, 60, and 90, then the side lengths equal x (30), 2x (60), and x√(3) (~51.9).

Canned dog food is on sale for 20% off the original price. What is the discount of a can if the original price is $1.35?

konstantin123 [22]

Answer:

1.08

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 1.35 × 20/100

Discount = 27/100

You save = $0.27

Final Price = Original Price - Discount

Final Price = 1.35 - 0.27

Final Price = $1.08

Hope this helps (:
