When you have something to an exponent and the exponent is a fraction it basically means the numerator is the power of the number and denominator is the root of the number.
81^3= 531441
4 root (531441)=27
if you have a graphing or scientific calculator you should be able to enter straight in 81^(3/4).

Olegator [25]

Answer:

Answer is attached in images

Step-by-step explanation:

Given:

x+z=1 and

z=4-x^{2} -y^{2}

Now,

1-x=4-x^{2} 2-y^{2} 2\\x^{2} -x+y^{2} \\x^{2} -x+1/4+y^{2} =3\\(x-1/2)^{2} +y^{2} =3+1/4\\(x-1/2)^{2} +y^{2} =(\sqrt(13)/2)^{2}

Which is circle with center (1/2,0) radius

\sqrt{13/2} take, x=1/2+\sqrt{3} /2 cos\alpha \\y=\sqrt{13}/2 sin\alpha        0\leq \alpha \leq 2\pi

Now,

The roof and exterior walls of a house represent intersecting planes. Using the image, name all the lines that are formed by the
Bess [88]

In the possible diagram of the house, the lines formed by intersecting planes are; \overline{AG}, \overline{ AB}, \overline{AH}, \overline{GF}, \overline{ BH}, \overline{HF}, \overline{BC}, \overline{ HD}, and \overline{FE}

<h3>What are the planes and the lines formed by them on the building?</h3>

The diagram found in a similar question has points <em>A</em>, G, B, H, and F on the roof.

The points on the walls of the house are; B, H, F, C, D, and E

A plane in Euclidean geometry is a surface that is flat, such that a line that connects two points on it lie completely on the plane.

A plane can be identified by three non collinear points that lay on it.

A line is a figure that does not have a curvature, width or depth, and it is infinitely long.

The planes on the roof are; ABH and AGHF

The planes on the walls of the house are; BCDH, and HDCF

The lines that are formed by the intersecting planes are therefore;

On the roof;

  • \overline{AG},  \overline{ AB},  \overline{AH}, \: \overline{GF},

Between the roof and the walls of the house;

  • \overline{BH},  \overline{HF}

Between the two sides of the walls;

  • \overline{BC},  \overline{ HD},  \overline{FE}

What is the solution for this system of equations? <br>y= -1/4x + 6<br>y= x+1​
snow_lady [41]

9514 1404 393

Answer:

  (x, y) = (4, 5)

Step-by-step explanation:

Equating the expressions for y gives ...

  -1/4x +6 = x +1

  5 = 5/4x . . . . . . . add 1/4x-1

  4 = x . . . . . . . . . . multiply by 4/5

  y = x +1 = 4 +1

  y = 5

The solution is (x, y) = (4, 5).
