The curl and the divergence of the vector field is illustrated below.

The term vector in math contains both position and magnitude.

Here we need to find the curl and the divergence of the vector field.

While we looking into the given question, we have the function

=> F(x, y, z) = <ex, exy, exyz>

AS per the concept of convergence, here we have consider that F=⟨P,Q,R⟩  is a vector field in  R3  and  Px, Qy,  and  Rz  all exist here then the divergence of F is defined by as,

=> div F = Px + Qy + Rz

=> div F = ∂P/∂x + ∂Q/∂y + ∂R/∂z.

The term curl in vector field is defined as a vector operator that describes the infinitesimal circulation of a vector field in three-dimensional Euclidean space

And the curl of the vector field is calculated as,

=> curl F = (Ry−Qz)i + (Pz−Rx)j + (Qx−Py)k

=> curl F = (∂R/∂y−∂Q/∂z)i + (∂P/∂z−∂R/∂x)j + (∂Q/∂x−∂P/∂y)k.

Answer:

d = 18

Step-by-step explanation:

d = square root (x2 -  x1)^2 + (y2 - y1)^2

Point A ( -1,2) Point B (1,-2)

Now let's put the number in

d = square root ( 1 -(-1)^2 + (-2 - 2)^2

Now let's get rid of the square root, and we have

(1-(-1) + (-2 -2)^2

2 + (-4)^2

2 + 16

18

So, the distance AB = 18

Answer:

[tex]AB = 4.5[/tex]

Step-by-step explanation:

⭐To find the distance between two points, you can use the distance formula: [tex]d = \sqrt{(x_2-x_1)^2 +(y_2 - y_1)^2}[/tex], where:

First, identify the coordinates you need to find the distance between, and label one coordinate as [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex].

Next, substitute [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] into the distance formula.

[tex]d = \sqrt{(1-(-1))^2+(-2-2)^2}[/tex]

[tex]d = \sqrt{(1+1)^2+(-4)^2}[/tex]

[tex]d = \sqrt{2^2+(-4)^2}[/tex]

[tex]d = \sqrt{4+16}[/tex]

[tex]d = \sqrt{20}[/tex]

∴ d ≈ 4.5

The volume of a pyramid that has the same base and height if a prism has a volume of 45 m cube is 15 cu. m.

In this question we have been given the volume of a prism which is of 45 m cube.

we need to find the volume of a pyramid that has the same base and height.

We know that the formula of the volume of prism is:

V = base area * height of prism  

From given, V = 45 m^3

But as we know prism and pyramid have same base area and height.

We know that the formula for the volume of pyramid.

volume of pyramid = 1/3 * base area * height

volume of pyramid = 1/3 * V

volume of pyramid = 1/3 * 45

volume of pyramid = 15 cubic meter

The unit conversion from celsius to fahrenheit is given by the formula

F = (9/5)C + 32.

The same attribute is expressed using a unit conversion but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.

We know we can convert temperatures from celsius to fahrenheite or from fahrenheite to celsius.

The conversion of celsius to fahrenheit is given by the formula,

C = (5/9)(F - 32).

Now, we have to solve for F.

C = (5/9)F - (160/9).

Now to get rid of the fraction we'll multiply 9 to each term.

9C = 5F - 160.

5F = 9C + 160.

Solving for F we have,

In Euclidean geometry, parallel lines (lines that never intersect) are equidistant in the sense that the distance of any point on one line from the nearest point on the other line is the same for all points.

In geometry, parallel lines can be defined as two lines in the same plane that are at equal distance from each other and never meet. They can be both horizontal and vertical. We can see parallel lines examples in our daily life like a zebra crossing, the lines of notebooks, and on railway tracks around us.

The equation for adding "n" numbers in a row is [a + (a + 1) + (a + 2) +.... a + (n-1)]. As a result, (n/2) (first number + last number) is the sum of "n" consecutive numbers or "n" terms of AP (Arithmetic Progression). The formula for even consecutive numbers is 2n, 2n+2, 2n+4, 2n+6, and so on.

The next two odd consecutive integers are (2n + 3) and (2n + 5) if 2n + 1 is an odd number. For illustration, assume that 2n + 1 is the odd number 7. Its successive numbers are identified as (7 + 2) and (7 + 4), or 9 and 11. Consecutive odd numbers are odd integers that are separated by 2 and come after one another. If the number x is odd, then the numbers x + 2, x + 4, and x + 6 are also odd.

Any collection of consecutive odd numbers starting with 1 has a sum that is always equal to the square of the total number of digits. If the numbers 1, 3, 5, 7, 9, 11,..., and (2n-1) are odd, then the sum of the first odd number is 1. First two odd numbers added together equal 1 + 3 = 4 (4 = 2 x 2).

Answer:

x = 3 and JL = 18

Step-by-step explanation:

JN and NL are equal to each other so set both equations equal to each other
15 - 2x = 4x - 3

solve for x by moving terms to other side

x = 3

plug in 3 for x in JN's equation

JN = 15 - 2(3)

JN = 9

Since JN and NL are equal to each other, JL is just the sum of those two lengths combined

so all you have to do is double JN

9 x 2

is 18

so JL is 18

Answer:

The circumference of a circle is given by the formula $C = 2\pi r$, where $r$ is the radius of the circle. In this case, the circumference of the circle is $13\pi$ cm, so we can set up the equation $13\pi = 2\pi r$ to solve for the radius. Dividing both sides by $2\pi$, we get $r = \frac{13\pi}{2\pi} = \frac{13}{2}$ cm. The area of a circle is given by the formula $A = \pi r^2$, so the area of this circle is $A = \pi \left(\frac{13}{2}\right)^2 = \frac{169}{4}\pi$ square cm. Therefore, the area of the circle is $\frac{169}{4}\pi$ square cm.

Answer:

[tex]b=\dfrac{2V}{ah}-c[/tex]

Step-by-step explanation:

Given equation:

[tex]V=\dfrac{1}{2}a(b+c)h[/tex]

Multiply both sides of the equation by 2:

[tex]\implies 2 \cdot V=2 \cdot \dfrac{1}{2}a(b+c)h[/tex]

[tex]\implies 2V=a(b+c)h[/tex]

Divide both sides by ah:

[tex]\implies \dfrac{2V}{ah}=\dfrac{a(b+c)h}{ah}[/tex]

[tex]\implies \dfrac{2V}{ah}=b+c[/tex]

Subtract c from both sides:

[tex]\implies \dfrac{2V}{ah}-c=b+c-c[/tex]

[tex]\implies \dfrac{2V}{ah}-c=b[/tex]

Step-by-step explanation:

Given 64 feet of fencing that can be used for three sides of a rectangular enclosure next to a barn wall, you want a function for area in terms of enclosure width, the width that maximizes area, and the maximum area.

If we define the width (x) as the dimension parallel to the barn wall, then the fence available for the "height" (out from the barn wall) is (64-x) in length. Half that is used on either end of the enclosure, so the area is ...

  A = WH

  A(x) = x(64 -x)/2

We notice this function describes a parabola that opens downward, with zeros at x=0 and x=64. The vertex (maximum) is on the line of symmetry, halfway between the zeros:

  x = (0 +64)/2 = 32

The width that maximizes area is x = 32 ft.

Using x=32 in the area formula, we find the maximum area to be ...

  A(32) = 32(64 -32)/2 = 1024/2 = 512 . . . . square feet

The maximum area is 512 square feet.

Additional comment

Perhaps you can see that the best width is half the length of the available fence. The other half of the fence is used for the ends of the enclosure. This is the generic solution to this kind of problem.

It is formed by simply drawing lines connecting the data points. Also called linear chart.

A line chart is a graphical representation of changes that occur over a period of time. A line chart has a horizontal axis called the x-axis and a vertical axis called the y-axis. The x-axis usually has a period of time over which we want to measure the quantity of a particular thing or item on the y-axis. Line charts are useful for analyzing trends, whether the quantity on the y-axis is increasing or decreasing over time. A line chart clearly shows an uptrend or a downtrend.

The line chart above represents bike sales by bike company from January to June, with the x-axis representing the time interval and the y-axis representing the number of bikes sold per month. Black dots in the graph indicate data points. A data point in a line chart represents the magnitude or number corresponding to a specific time on the x-axis. In this example, 50 bikes were sold in January. 30 bikes were also sold in February. This data can be interpreted by month using data points. Line segments connecting these individual data points show whether bike sales are trending upwards or downwards.

A. From the Limit Comparison Test, the series converges conditionally.

The Limit Comparison Test can be used to determine whether a given series converges or diverges. In this case, the given series is sigma^infinity_k = 0 9(-1)^k/k^4 + 2.

To use the Limit Comparison Test, we need to compare the given series to a known series. For example, we can compare it to the series sigma^infinity_k = 1/k^4.

We can then calculate the ratio of the two series:

sigma^infinity_k = 0 9(-1)^k/k^4 + 2

sigma^infinity_k = 1/k^4

Ratio: sigma^infinity_k = 0 9(-1)^k / (1/k^4)

Since the limit of the ratio of two series is a finite number, the given series converges. However, since the ratio is not 1, it converges conditionally, not absolutely.
