curve before applying the theorem.)F(x, y) = y cos(x) − xy sin(x), xy + x cos(x), C is the triangle from (0, 0) to (0, 12) to (3
Serhud [2]

C has a clockwise orientation, so in order to use Green's theorem (which is probably the "theorem" mentioned here), we have

\displaystyle\int_C\vec F\cdot\mathrm d\vec r=-\iint_D\frac{\partial(xy+x\cos x)}{\partial x}-\frac{\partial(y\cos x-xy\sin x)}{\partial y}\,\mathrm dx\,\mathrm dy

where D is the triangle region.

=\displaystyle\int_0^3\int_0^{12-4x}(\cos x-x\sin x)-(y+(\cos x-x\sin x))\,\mathrm dy\,\mathrm dx

=\displaystyle-\int_0^3\int_0^{12-4x}y\,\mathrm dy\,\mathrm dx=\boxed{-72}

{x{ x + 4<0 or 6x>-12)
lora16 [44]

Answer:

x\in (-\infty , -4) \cup (-2,+\infty)

Step-by-step explanation:

Solve the system of inequalities:

x + 4 < 0

OR:

6x > -12

The first inequality yields the solution:

x < -4

The second inequality gives the solution:

x > -2

The total solution is the disjunction of the individual solutions, i.e., the union of both.

It can be expressed as

\mathbf{x\in (-\infty , -4) \cup (-2,+\infty)}

Find the slope of the line through the points (13,14) and (0,−1)
timofeeve [1]

Answer:

1.15 or \frac{15}{13}

Step-by-step explanation:

1. The slope can be found with this formula: \frac{y2-y1}{x2-x1}

2. Let's plug in the numbers: \frac{14--1}{13-0}

4. \frac{15}{13} ≈ 1.1538

The correct answer will be marked as brainliest ! Please help me
Oksana_A [137]
The answer is D. It's always Rise over Run. So the slope would be 2/1 Or 2.
