Answer:
<h2>D</h2>Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about</h3>- inequality
- algebra
- PEMDAS
first note: it will be more easy if we solve the inequality first
so let's solve it together
so what we get
we get that x is greater than 12
<h2>so the answer would be d</h2>A function assigns the values. The function f = xy²-2x² satisfies a conservative vector field F = ∇f.
<h3>What is a Function?</h3>A function assigns the value of each element of one set to the other specific element of another set.
Given F(x,y) = (y² - 4x) i + 2xy j, and it is needed to be known that,
Let's look for a primitive of y²-4x with regard to x. Because we regard y (and y²) as constants, a primitive of y² is xy², just as a primitive of k is xk (because we treat y² as a constant). Because a primitive of x equals x²/2, a primitive of 4x is 2x². As a result, a primitive of y²-4x is xy²-2x². We can get any other primitive by adding constants, but because we considered y as a constant, we have that.
f(x,y) = xy²-2x²+c(y)
where c(y) only depends on y (thus, it is constant respect with x).
To learn more about c(y), we shall deduce the formula in terms of y.
Thus, d/dy is constant. We can take f(x,y)=xy²-2x². This function f satisfies that F = ∇f.

Answer:
Does not exist
Step-by-step explanation:
Apply the divergence test.
⇒ diverges
If an infinite series is a divergent sequence, <u>it has no limit.</u>
~Hope this helps!~
(Yes I did answer twice since you asked the question twice :P)
