What is the solution to the equation below?

olasank [31]

A. W=2/12

4w=2/3

(Divide both sides of the equation by 4)

4w/4=2/3/4

(Any expression divided by it’s self is 1)

w=2/3/4

(To divide a fraction by a number, multiply by it’s reciprocal)

w=2/3 • 1/4

(Reduce the numbers with the greatest common factor 2)

w= 1/3 • 1/2

(Multiply the fractions)

w= 1/3 • 1/2= 1/6

1/6=2/12

6^3=216. Using exponents, write three more expressions whose value is 216.

faltersainse [42]

Answer:

$216^1$

$(2^3)(3^3)$

$(2*2^2)(3*3^2)$

Step-by-step explanation:

To solve this exercise you must keep on mind that according to the exponents rules:

$(a^m)(a^n)=a^{(m+n)}$

$a^1=a$

1) Therefore, you can write 216 as:

$216^1$

Because: $216^1=216$

2) Descompose the number 216 into its prime factors, then:

$216=2*2*2*3*3*3=(2^3)(3^3)$

Then you can write the number 216 as $(2^3)(3^3)$

3) You can also write 216 as following:

$(2*2^2)(3*3^2)$

Find the volume of the region between the planes x plus y plus 2 z equals 2 and 4 x plus 4 y plus z equals 8 in the first octant

Alex787 [66]

Find the intercepts for both planes.

Plane 1, x + y + 2z = 2:

$y=z=0\implies x=2\implies (2,0,0)$

$x=z=0\implies y=2\implies(0,2,0)$

$x=y=0\implies 2z=2\implies z=1\implies(0,0,1)$

Plane 2, 4x + 4y + z = 8:

$y=z=0\implies4x=8\implies x=2\implies(2,0,0)$

$x=z=0\implies4y=8\impliesy=2\implies(0,2,0)$

$x=y=0\implies z=8\implies(0,0,8)$

Both planes share the same x- and y-intercepts, but the second plane's z-intercept is higher, so Plane 2 acts as the roof of the bounded region.

Meanwhile, in the (x, y)-plane where z = 0, we see the bounded region projects down to the triangle in the first quadrant with legs x = 0, y = 0, and x + y = 2, or y = 2 - x.

So the volume of the region is

$\displaystyle\int_0^2\int_0^{2-x}\int_{\frac{2-x-y}2}^{8-4x-4y}\mathrm dz\,\mathrm dy\,\mathrm dx=\displaystyle\int_0^2\int_0^{2-x}\left(8-4x-4y-\frac{2-x-y}2\right)\,\mathrm dy\,\mathrm dx$

$=\displaystyle\int_0^2\int_0^{2-x}\left(7-\frac72(x+y)\right)\,\mathrm dy\,\mathrm dx=\int_0^2\left(7(2-x)-\frac72x(2-x)-\frac74(2-x)^2\right)\,\mathrm dx$

$=\displaystyle\int_0^2\left(7-7x+\frac74 x^2\right)\,\mathrm dx=\boxed{\frac{14}3}$
