div( curl( grad f )) - scalar field; the divergence of a vector field is a scalar field

A quantity with both direction and magnitude, particularly when used to depict the distance between two points in space.

In a scalar field, each point in a space—possibly actual space—is assigned a single integer.

According to the given information

(a) You can only determine the curl of a vector field; curl f is meaningless.

(b) grad f - vector field; when you take a gradient of something , it results in a vector field

(c) div F - scalar field; take the divergence of a vector field, it results in a scalar field

(d) A vector field is produced by the operation curl(grad f) on a vector field.

(e) grad F - meaningless; gradients are only used for scalar fields

(f) grad( div F ) - vector field; the gradient of a scalar field is a vector field

(g) div( grad f ) - scalar field; if you take divergence of a vector field, the result is a scalar field

(h) Grad (div f) is useless; one cannot take a scalar field's divergence into account.

(i) vector field; a vector field is a vector field's curl (curl F).

(j) div(div F) is useless; it is impossible to calculate a scalar field's divergence.

(k) ( grad f ) x ( div F ) - meaningless; you cant cross a scalar field by a vector field !

(l) The divergence of a vector field is a scalar field, and its formula is div(curl(grad f))

The length FE in the circle is 6 units

The arc AE has a measure of 64 degrees

From the question, we have the following parameters that can be used in our computation:

The circle

Given that the lengths from the center to either chords are equal

This means that

FE = 6 units

For the other circle, we have

BC = 58 degrees

AB = ED

The arc AE is calculated as

AE = 180 - BC - ED

Where

AB = ED = BC = 58 degrees

So, we have

AE = 180 - 58 - 58

Evaluate

AE = 64

Hence, the arc AE is 64 degrees

The Correct answer is option b. The proportion of this population that lies at or below x=87 is 0.3085.

We can conclude that the proportion of this population that lies at or below x=87 is 0.6915 because the graph shows that the area under the curve to the left of x=87 is 0.3085. However, we cannot conclude that the proportion of this population that lies at or below x=87 is 0.3085 because this statement is contradictory to the information provided in the graph.

The area under the curve to the left of x=87 represents the proportion of the population that lies at or below x=87, so it cannot also be equal to the proportion of the population that lies at or above x=87.

\(x = 1-10t\\y = -6+16t\\z = 7-12t\)

Step-by-step explanation:

We are given the coordinates of points P(1,-6,7) and Q(-9,10,-5).

The values in the form of (\(x,y,z\)) are:

\(x_1=1\\x_2=-9\\y_1=-6\\,y_2=10\\z_1=7\\z_2=-5\)

\($\vec{PQ}$\) can be written as the difference of values of x, y and z axis of the two points i.e. change in axis.

\(\vec{PQ}=<x_2-x_1,y_2-y_1,z_2-z_1>\)

\(\vec{PQ} = <(-9-1), 10-(-6),(-5-7)>\\\Rightarrow \vec{PQ} = <-10, 16,-12>\)

The equation of line in vector form can be written as:

\(\vec{r} (t) = <1,-6,7> + t<-10,16,-12>\)

The standard parametric equation can be written as:

\(x = 1-10t\\y = -6+16t\\z = 7-12t\)

There will be 12 slices of pizza left over, which can be expressed as 3/2 or 1 1/2 slices in fraction form.

To find out how much pizza will be left over, we need to calculate the total number of slices available and subtract the number of slices consumed by the players.

Given that there are six pizzas and each pizza has eight slices, the total number of slices available is 6 pizzas * 8 slices/pizza = 48 slices.

Since there are 36 players on the team, and each player has one slice, the total number of slices consumed is 36 slices.

To determine the remaining slices, we subtract the consumed slices from the total available slices: 48 slices - 36 slices = 12 slices.

Therefore, there will be 12 slices of pizza left over.

To express this as a fraction, we can write it as 12/1, which simplifies to 12. This means there will be 12 whole slices of pizza left over.

If you would like to express it as a fraction in its simplest form, you can write it as 12/8. By dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 3/2. So, in fraction form, there will be 3/2 or 1 1/2 slices of pizza left over.

The slope of the line is 0.34, which means that the price of the bear increase by $0.34 each year.

An equation is an expression that shows the relationship between two or more variables and numbers.

Let y represent the cost per pound of the gummy bears and x represent the years after 2000.

a) In 2000, Carl’s Candy Shop sold gummy bears for $0.38 per pound, that is (0, 0.38) while in 2008 they cost $0.72 per pound that is (8, 0.72). Hence:

y - 0.38 = [(0.72 - 0.38) / (8 - 0)](x -0)

y = 0.0425x + 0.38

b) The slope of the line is 0.0425, which means that the price of the bear increase by $0.0425 each year.

c) in 2003, x = 3, hence:

y = 0.0425(3) + 0.38 = 0.5075

Answer:

(-2,5), refer to the step-by-step. Feel free to comment any questions you may have!

Step-by-step explanation:

Given the system of equation, \(\left \{ {{x+6y=28} \atop {2x-3y=-19}} \right.\), solve by elimination.

\(\left \{ {{-2(x+6y=28)} \atop {2x-3y=-19}} \right.\) , multiply the top equation by -2.

We get,  \(\left \{ {{-2x-12y=-56} \atop {2x-3y=-19}} \right.\)

\(+ {{-2x-12y=-56} \atop {2x-3y=-19}} \right.\), add the equations together.

We get, \(-15y=75\), we just eliminated the variable, x, we can now solve this equation for y.

\(-15y=-75 = > y=\frac{-75}{-15}\), \(y=\frac{75}{15} = > y=5\)

We just found the value y, which is y=5. Now we can take this value and plug it into y for either of the two original equations and solve for x. I will take the top equation...

\(x+6y=28 = > x+6(5)=28 = > x+30=28\), subtract the value, 30, from both sides. We get, \(x=-2\).

We found the value x, x=-2.

Thus the solution to the given system of equations is (-2,5).

Answer:

(-2, 5)

Step-by-step explanation:

Given linear system of equations:

\(\begin{cases}x+6y=28\\2x-3y=-19\end{cases}\)

To solve by the method of elimination, first multiply the first equation by -2:

\(\implies -2 (x+6y=28)\)

\(\implies -2x-12y=-56\)

Add this to the second equation to eliminate the term in x:

\(\begin{array}{lrcrcr}& 2x & - & 3y & = & -19\\+\vphantom{\dfrac12}&(-2x & - & 12y & = & -56\\\cline{2-6}&\vphantom{\dfrac12}&- & 15y & = &-75\end{array}\)

Solve the expression for y:

\(\implies -15y=-75\)

\(\implies y=5\)

Substitute the found value of y into the expression for x and solve for x:

\(\implies x=28-6(5)\)

\(\implies x=28-30\)

\(\implies x=-2\)

Check by substituting the found values of x and y into both equations.

Equation 1

\(\implies -2+6(5)=-2+30=28\)

Equation 2

\(\implies 2(-2)-3(5)=-4-15=-19\)

Hence proving that the solution (-2, 5) is true.
