Answer:

17

Step-by-step explanation:

since it is in the middle you can just divide by 3 since one will be greater and one will be less so 51/3=17

Assume the second number to be x, then the first numbers is X-2, third number is x + 2
Thus we have a sequence of x-2,x,x+2,the sum of these number is 51:
X-2+x+x+2=51
X=17
So, 15, 17, 19

1. Use the slopes (5, 7) and (-4, -2) from the previous question to describe each line as slanting downward, slanting upward, ho
Sedaia [141]

Answer:

1. slanting upward because the slope is positive one.

2. A: 3/4     B: 4/-3

3. A: 3        B: y=3x-10

Step-by-step explanation:

1. (-2-7)/(-4-5) = -9/-9 = 1

2. A: (7-4)/(7-3) = 3/4

   B: (8-0)/(-6-0) = 8/-6 = 4/-3

3. find the slope first so (4-1)/(2-1)= 3/1. then you plug in point C to find the y intercept so y=mx+b would be 2=3(4)+b which makes it so b is -10. the new equation would be y=3x-10

A fluid has density 810 kg/m3 and flows with velocity v = z i + y2 j + x2 k, where x, y, and z are measured in meters and the co
mixas84 [53]

Denote the cylindrical surface by S, and its interior by R. By the divergence theorem, the integral of \vec v across S (the outward flow of the fluid) is equal to the integral of the divergence of \vec v over the space it contains, R:

\displaystyle\iint_S\vec v\cdot\mathrm d\vec S=\iiint_R(\nabla\cdot\vec v)\,\mathrm dV

The given velocity vector has divergence

\vec v=z\,\vec\imath+y^2\,\vec\jmath+x^2\,\vec k\implies\nabla\cdot\vec v=\dfrac{\partial(z)}{\partial x}+\dfrac{\partial(y^2)}{\partial y}+\dfrac{\partial(x^2)}{\partial z}=2y

Then the total outward flow is

\displaystyle\iiint_R2y\,\mathrm dV

Converting to cylindrical coordinates gives the integral

\displaystyle2\int_0^{2\pi}\int_0^3\int_0^4r^2\sin\theta\,\mathrm dz\,\mathrm dr\,\mathrm d\theta=\boxed{0}

G(x)=3x^2+6x−9<br><br> I need the vertex for this please
aleksley [76]

Answer:

-1, -12

Step-by-step explanation:

you take b which is 6 and make it negative, then you take a and multiply it by 2, which is 6. you then take the 2 numbers and put the -b over 2a in this formula -b/2a giving you -1 as your x value

after you do that, you input the -1 into the equation as x and the value you get out of that (-12) is the y value of the vertex
