The answer choice which represents a pair of complementary angles in the task content is; angles DEH and DEJ.

<h3>Which pair of angles represent complementary angles?</h3>

It follows from the concept of angle geometry that two or more angles are said to be complementary when the sum of their measures is 90°.

It follows from the task content therefore that since, DEJ = 90° and the sum of the measures of angles DEH and DEJ amounts to 90°.

Hence, the pair of angles are complementary.

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

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

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

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

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

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

PolarNik [594]

Step-by-step explanation:

working ;

(3x+2)^2

*Apply Perfect Square Formula : (a+b) =a^2+2ab+b^2

a = 3x,b = 2

(3x)^2 + 3x.2+2^2

finally Answer is:

= 9x^2 + 12x +4

The length of a rectangle is 4 inches longer than its width. The area of the rectangle is 12 square inches. What are the length

azamat

Answer: B) w(4+w)=12

Step-by-step explanation: Because the formula for area is length times width, the expression used to find it would by w•l. If L=4+W, the equation for area in this question is w(4+w)=12

ANYEONESSSSSSSSSS???

Dmitriy789 [7]

Answer:

C. 2

Step-by-step explanation:

To solve slope, the formula is $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ . 9-3 is 6 and 5-2 is 3. So simplify 6/3 to 2.

Hope it's correct!
