I’m not 100% sure but isn’t it x2 +xy +y2?

Step-by-step explanation:

$A = x^2-xy+y^2\\C =x^4+x^2y^2+y^4$

We will now divide C with A.

$\frac{x^4+x^2y^2+y^4}{x^2-xy+y^2}$

Divide x^2, -xy, y^2. Remember that dividing exponents results in subtracting. $x^4 / x^2 = x^2\\4 - 2 = 2$

So:

$\frac{1}{x^2+xy+y^2}$

Help me with this please!!

<h2><u>Given:</u><u>-</u></h2>

Points C = (-7,2) → $\sf{(X_1,Y_1)}$
D = (3,12) → $\sf{(X_2,Y_2)}$

The Midpoint of CD.

<h2><u>Required</u><u> </u><u>Response</u><u>:</u><u>-</u></h2>

Let,

Midpoint of CD be (x,y).

WKT,

$\boxed{\sf{(x,y) = \frac{X_1+X_2}{2},\frac{Y_1+Y_2}{2}}}$

$→\;{\sf{\frac{-7+3}{2},\frac{2+12}{2}}}$

$→\;{\sf{\frac{-4}{2},\frac{14}{2}}}$

$→\;{\sf{-2,7}}$

The Midpoint of CD ◕➜ $\Large{\red{\mathfrak{(-2,7)}}}$

Let,

The centre be O

Radius = CO & OD

Here, C = (-7,2) → $\sf{(X_1,Y_1)}$

O = (-2,7) → $\sf{(X_2,Y_2)}$

$\boxed{\sf{Distance = \sqrt{(X_2-X_1)²+(Y_2-Y_1)²}}}$

$→\;{\sf{\sqrt{(-2+7)²+(7-2)²}}}$

$→\;{\sf{\sqrt{5²+5²}}}$

$→\;{\sf{\sqrt{25+25}}}$

$→\;{\sf{\sqrt{50}}}$

$→\;{\sf{5√2 (or) 7.07}}$

Radius of Circle ◕➜ $\Large{\red{\mathfrak{7.07}}}$

Es un número disminuido en cuatro su resultado es ocho

NARA [144]

Resolviendo una resta, veremos que el número es igual a 12.

<h3>¿Como encontrar el número?</h3>

Definamos X como nuestro número, sabemos que cuando este número es disminuido en cuatro (es decir, le restamos 4 a nuestro número X) el resultado es 8.

Entonces, lo que tenemos que hacer es resolver la operación:

X - 4 = 8

Para resolver esto, lo que tenemos que hacer es sumar 4 en ambos lados de esta ecuación, asi obtenemos:

X - 4 + 4 = 8 + 4

X = 12

De esta forma, concluimos que nuestro número es igual a 12.

The object on the right is made from a square based pyramid...

natima [27]

Answer:

$7.81\ g/cm^3$

Step-by-step explanation:

step 1

Find the volume of the cuboid

The volume is equal to

$V=(6^2)(9)=324\ cm^3$

step 2

Find the mass of the cuboid

Remember that

The density is equal to divide the mass by the volume

The mass is equal to multiply the volume by the density

$m=(324)(0.68)=220.32\ g$

step 3

Find the mass of the square base pyramid

subtract the mass of the cuboid from the total mass

$970-220.32=749.68\ g$

step 4

Find the volume of the pyramid

The volume is equal to

$V=\frac{1}{3}(6^2)(8)= 96\ cm^3$

step 5

Find the density of the steel (pyramid)

divide the mass of the pyramid by the volume of the pyramid

$749.68/96=7.81\ g/cm^3$

Help me with this question plzzzzzzz

valkas [14]

Answer:

The base is <u>9.4 milliliters</u>

Step-by-step explanation:

First, you would notice that they give you the perimeter of it. Meaning 51.4 was a sum of adding the height and base length twice. So you would take 51.4 and subtract 16*2 from it. Which would be 19.4. Next, since 19.4 would be both bases added, and they are both the same, you would do 19.4/2=9.4

The base is 9.4 milliliters.
