Consider the paraboloid z=x2+y2. the plane 4x−8y+z−10=0 cuts the paraboloid, its intersection being a curve. find "the natural"
VladimirAG [237]

4x-8y+z-10=0\implies4x-8y+x^2+y^2-10=0


Complete the square to get


x^2+4x+4-4+y^2-8y+16-16-10=0


(x+2)^2+(y-4)^2=30


Now let


x+2=\sqrt{30}\cos t

y-4=\sqrt{30}\sin t


and the intersection can be expressed as a function of t,


\mathbf r(t)=(\sqrt{30}\cos t-2,\sqrt{30}\sin t+4)


with 0\le t\le2\pi.

Absolute power x -8=-5
solong [7]

Add 8 to both sides (-5)

-8 is going to cancel out so it will get ride of -8 and it will only add -5

-5+8=3

then all you have left is x

so it would be x=3

What is the answer to, -2x - 13 = -3x - 5​
shtirl [24]

-2x - 13 = -3x - 5​

Step 1: Combine like terms

x's go with x's (-2x and -3x). To do this add 2x to both sides

(-2x + 2x) - 13 = (-3x + 2x) - 5​

(0) - 13 = (-x) - 5​

- 13 = -x - 5​

normal numbers go with normal numbers ( -13 and -5). To do this add 5 to both sides

(- 13 + 5) = -x + (- 5 +​ 5)

-8 = -x + (0)

-8 = -x

Step 2: Isolate x by dividing -1 to both sides (this will take the negative sign away from the x)

\frac{-8}{-1} =\frac{-x}{-1}

8 = x

x= 8

Hope this helped!

Which polynomial is in standard form?
Tamiku [17]

Answer:

D). 5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9

Step-by-step explanation:

For better clarity let us re write the options

A).2xy^3+3x^3y^4-4x^4y^5+9x^5y^6

B).8x^5-5y^4-2xy^5+x^2y

C).x^3y^2-3x^2y-9x^4y^3+11x

D).5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9

To express polynomial with mixed variables in standard form, we begin by the highest coefficient of x to the smallest (we place high precedence on the coefficient  x terms)
