Answer:

It's the second option

The formula for Area is A= 1/2bh ( b stand for base & h for height)

Which of these best describes d, the dimeter of a circle
Paraphin [41]
2 x radius.
Description
In geometry, a diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.

Let f = (ax + by + 4z) i + (x + cz) j + (9y + mx) k where a, b,c, and m are constants.
Tom [10]
Let \mathcal R be an arbitrary closed region with boundary the surface \mathcal S. By the divergence theorem,

\displaysytle\iint_{\mathcal S}\mathbf f(x,y,z)\cdot\mathrm d\mathbf S=\iiint_{\mathcal R}\nabla\cdot\mathbf f(x,y,z)\,\mathrm dV

We have

\nabla\cdot\mathbf f(x,y,z)=\dfrac{\partial(ax+by+4z)}{\partial x}+\dfrac{\partial(x+cz)}{\partial y}+\dfrac{\partial(9y+mx)}{\partial z}=a

so that the flux satisfies

\displaystyle a\iiint_{\mathcal R}\mathrm dV=0

We're assuming \mathcal R is a closed region, and the integral above is its volume, which must be positive. This means we must have a=0.

What is the vertex of the absolute value function below?
Stels [109]

Answer: Choice B

The vertex is (-3, 2)

===========================================================

Explanation:

The vertex is the lowest point of a V shaped graph like this. If the V was upside down, then the vertex would be the highest point. The graph shows that (-3, 2) is the lowest point.

Side note: The equation for this absolute value function is y = |x+3|+2

Find the slope of the given points (3,4) and (7,-4)
mr Goodwill [35]

Answer:

<h2>         m = -2</h2>

Step-by-step explanation:

\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}

(3, 4)    ⇒   x₁ = 3,  y₁ = 4

(7, -4)    ⇒   x₂ = 7,  y₂ = -4

So the slope:

                    \bold{m=\dfrac{-4-4}{7-3}=\dfrac{-8}4=-2}
