Step-by-step explanation:

come on ! this is so simple. with just a tiny little bit of thinking you get this yourself.

1 inch = 50 miles.

so, how many miles are then 2 inches ? hmmm ?

could it be that it is just 2×1 inch = 2×50 miles ?

yes ! it is that simple !

2×50 = 100 miles.

and so, how many miles are 3 inches ?

uuuuuhhhh !

what do you think ?

3×1 inch = 3×50 miles

yeah !

3×50 = 150 miles !

yes, so simple, so easy.

this is like the old questions like "every child gets 2 pieces of candy. there are 6 children. how many pieces of candy do we need ?"

Instructions:Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Svetllana [295]

Answer:

D = 108°

F = 180°

H = 252°

I = 288°

Explanation:

Every regular polygon with n sides can be divided into n congruent triangles. The angle with vertex the center of the polygon will measure 360 : n degrees. This will also be the angle of rotation under which the polygon matches itself.

We are given a regular decagon, therefore:

n = 10

α = 360 : n = 36°

We consider that, if the decagon is not rotated, A' coincides with A and the rotation is towards the next letter of the alphabet. This means that after one rotation of 36° A' will coincide with B, after two rotations A' will coincide with C and so on.

A' will coincide with D after three rotations: 3 × 36° = 108°

A' will coincide with F after five rotations: 5 × 36° = 180°

A' will coincide with H after seven rotations: 7 × 36° = 252°

A' will coincide with I after eight rotations: 8 × 36° = 288°

Finger [1]

Answer:

x^4 - 3x^3 + 3x^2 - 2x + 4

Step-by-step explanation:

(x^4 - 3x^3 + 3x^2 - 3x + 6) + (x - 2)

Reorder

x^4 - 3x^3 + 3x^2 - 3x+x + 6-2

Simplify

x^4 - 3x^3 + 3x^2 - 2x + 4

Find the net outward flux of f=a×r across any smooth closed surface in r3, where a is a constant nonzero vector and r=〈x,y,z〉

Paul [167]

Flux is zero since asked in $\pi$ is $0\pi$ .

Flux is the presence of a pressure field in a detailed physical medium or the glide of electricity through a surface. In electronics, the term applies to any electrostatic field and any magnetic subject. Flux is depicted as "traces" in a plane that contains or intersects electric powered fee poles or magnetic poles.

The definition of flux is a flow of liquid from the body, or a regular movement or exchange. An instance of flux is diarrhea. An example of flux is an ever-converting list of the responsibilities of a particular process. regular or frequent alternate; fluctuation.

Flux is a go-platform computer program that adjusts a show's color temperature in keeping with vicinity and time of day, offering practical respite for the eyes. the program is designed to reduce eye stress at some stage in night-time use, supporting reducing the disruption of sleep patterns.

Our field is IR^3 be,

F= (bz-cy,cx-az,ay-bx)

Now divergence theorem says that Flux can be calculated by

$\int\limits^ {} \, F.n = \int\limits^ {} \,( c.F) dv$

Now let's calculate the divergence of a vector field

F = (ia/ax + ja/ay + k*a/az)*((bz-cy)i+((x-dz))+(ay-bx)*k)

a/ax(bz-cy)+a/ay(cx-az)+a/az(ay-bx)

= 0+0+0

Flux is zero since asked in $\pi$ is $0\pi$ .
