Answer:

F=dA  

dF=0  

d⋆F=⋆J  

where in fact the second equality is not needed because of the identity  d2=0 . In abstract tensor notation, these equations expand to

Fab=2∇[aAb]  

∇[aFbc]=0  

∇aFab=Jb  

where in the above, additional compact notation has been used to simplify things: square brackets mean antisymmetrizing indices, and the covariant derivative  ∇a  is related to a flat derivative  ∂a  and a connection  Γbac . Now, performing a 3+1 decomposition (here in flat space-time) Maxwell's equations break down as

∇⋅B⃗ =0  

∇⋅E⃗ =4πρ  

∂B⃗ ∂t=−∇×B⃗  

∂E⃗ ∂t=+∇×B⃗ −4πJ⃗ .  

In the above, there is yet more compactifying notation: the divergence is defined as

∇⋅v⃗ =∂vi∂xi  

and the curl is defined as

(∇×v⃗ )i=ϵijk∂vk∂xj.  

In the above, still more compactifying notation has been used, namely the Einstein summation convention. Written out in components, the divergence is

∇⋅v⃗ =∂vx∂x+∂vy∂y+∂vz∂z  

and curl is defined as

(∇×v⃗ )z=∂vy∂x−∂vx∂y  

and similarly for the other two components.

As you can see, the extremely compact and powerful notation

dF=0  

d⋆F=⋆J  

expands out to a large set of component equations—but they have the same content, so it's not very meaningful that the equations in components are much longer than in terms of differential forms.

As another example, Elson Liu answered with an exploded-out form of the Standard Model Lagrangian. However, it can be written much more compactly:

L=LYM+LHiggs+Llep.+Lqrk.+LYuk.  

where

LYM=−14TrFabFab  

LHiggs=−(Daϕ†)(Daϕ)+14λ(ϕ†ϕ−12v2)2  

Llep.=iℓ†I/DℓI+ie¯†I/De¯I  

Lqrk.=iq†I/DqI+iu¯†I/Du¯+id¯†I/Dd¯I  

LYuk.=−yIJϕℓIe¯J−y′IJϕqId¯J  

−y′′IJϕ†qIu¯J+h.c.  

and specifying that F is the curvature on the gauge group  G≃SU(3)⊗SU(2)⊗U(1) ,  Da  is the gauge covariant derivative on G,  /D  is the gauge covariant Dirac operator on G, and specifying the representations of the fields: the scalar  ϕ  in the rep (1,2,-1/2), and the fermions  ℓ  in the rep (1,2,-1/2),  e¯  in (1,1,+1),  q  in (3,2,+1/6),  u¯  in  (3¯,1,−2/3) , and  d¯  in  (3¯,1,+1/3) ; where I is a generation index running over 1,2,3, and where everything else is a constant.

Step-by-step explanation:

Answer:

C.

Step-by-step explanation:

Location 1 is 20 feet ABOVE the sea level while Location 2 is 50 feet BELOW the sea level.

Location 1 would be 20

Location 2 would be -50

And think of the greater than and lesser than symbol as a alligators mouth it would go towards the bigger number so, -50 < 20, Location 1 is higher, is the answer.

Answer:

23 × 23

Reasoning:

A prefect square is a number times itself

The product of the perfect square can therefore be a sqaure root

23 × 23= 529

Then if we square root 529 it would always be a whole number (23)

Answer: A 5

Step-by-step explanation:

20% * 25

= 5

She can expect to hit the bullseye 5 times.

Answer:

A. 5

Step-by-step explanation:

Regina throws 25 darts and hits the bullseye 20% of the time. So we would set up the equation as 0.20*25 (as we are looking for 20% of 25 and of means multiplication and 20% is 0.20). 0.20*5=5 so she can expect to hit the bullseye 5 times. Therefore, A is the correct answer choice.

Solution:  

The description about the graph is:  

Graph shows 0 to 30 on x axis at increments of 5 and 0 to 12 on y axis at increments of 1. The label on the x axis is Temperature in degree C, and the label on the y axis is Number of Sweaters Sold. Dots are made at the ordered pairs 0, 12 and 2.5, 10 and 2.5, 11 and 5, 10 and 7.5, 9 and 7.5, 10 and 10, 7 and 12.5, 6 and 12.5, 8 and 15, 4 and 15, 7 and 17.5, 5 and 20, 1 and 20, 3 and 22.5, 9 and 25, 1 and 27.5, 1.  

Part A:  The relationship between the temperature of the city and the sale of sweaters in the city can be found by drawing the line of best fit.  

If you will draw line through , (12.5,6) and (15,4), it will best represent line of best fit, because most of points on same and opposite side of line are equidistant from each other.

Equation of line passing through two points,[tex](x_{1},y_{1}),(x_{2},y_{2})is, \frac{y-y_{1} }{x-x_{1} } = \frac({y_{2} - y_{1}})({x_{2}-x{1} })[/tex]

Equation of line passing through (12.5,6) and (15,4) is given by

[tex]\frac{y-6}{x-12.5} = \frac{6-4}{12.5-15}[/tex]

[tex]2x-25=-2.5+15[/tex]

[tex]2x+2.5y=40[/tex]

[tex]20x+25y= 400[/tex]

[tex]4x+5y=80[/tex]

Part B: Description of line of best fit  

A line of best is the line which passes through all or some points or only through a single point, which describes the relationship between x and y values of data set. The line passes through (12.5,6), (15,4),and (7,10) that is three points.  

(C) 4 x + 5 y=80  

5 y= - 4 x +80

[tex]y=\frac{-4x}{5}+16[/tex]

Slope [tex]= \frac{-4}{5}[/tex], Y- intercept = 16

Answer:

1). x = 40

2). y = 20

Step-by-step explanation:

1). "4x" y "160" son ángulos de vértice, por lo que son congruentes entre sí. Entonces, "4x = 160" y luego usa álgebra para resolver "x" y "x = 40".

2). "Y" y "4x" son ángulos suplementarios, por lo que si ambos se suman, forman un ángulo de 180. Entonces, "Y + 4 (40) = 180", usando álgebra daría la respuesta "Y = 20".

¡Espero que esto ayude!

I think that the answer is C

Answer:

2.05x10^4

Step-by-step explanation:

The equation of the line is y=100x+500, which can be found through the given points.

So, if x=200, plug that into the equation of the line. y=100(200)+500

y=20000+500

y=20500

In scientific notation, that is 2.05x10^4

Hope this helps <3

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Probability of rolling an even number P(A):

[tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Probability of flipping tails P(B):

[tex]\frac{1}{2}[/tex]

P(A OR B) = P(A) + P(B) – P(A AND B)

[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{2}[/tex] - ([tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]) =  [tex]\frac{3}{4}[/tex]

I think 11 is the median for the data.

Answer: add 22 with $18.55  divide 50%

Step-by-step explanation:

As per linear equation, the equation to find the price of the shoe is: (11 + 0.5x) = 18.55.

The price of the shoe before discount is $15.1.

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, 'x' is a variable, 'A' is a coefficient and 'B' is constant."

Given, the price of the shirt before the discount is $22.

Let, the price of the shirt before the discount is $x.

Now, total price of the shirt and shoe $(22 + x).

Now, the total discount on shirt and shoe is

= $(22 + x) × 50%

= $(22 + x) × 0.5

= $(11 + 0.5x)

Now, (11 + 0.5x) = 18.55

⇒ 0.5x = 18.55 - 11

⇒ x = 7.55 ÷ 0.5

⇒ x = 15.10

Therefore, the price of the shoe before discount is $15.1.

Answer:

120 and 180 minutes have outliers

Step-by-step explanation:

An outlier is a point of data in a data set that is far out from the median in the data set. In this case, almost all of the data points are from 0 minutes of exercise to 60 minutes, except for two that are more than double that.

It could "skew" the data, as if you were to calculate the mean (average), it would be shifted slightly higher by these two outliers.
