If f(x, y, z) = xyzi + yj + zk, the divergence of the curl of the vector field f is zero.

To find the divergence of the curl of the vector field f(x,y,z) = xyzi + yj + zk, we first need to compute the curl of f, which is given by:

curl f = (∇ × f) = ∂(zk)/∂y - ∂(yj)/∂z + (∂(yj)/∂x - ∂(xyzi)/∂y)k + (∂(xyzi)/∂z - ∂(zk)/∂x)j + (∂(zk)/∂x - ∂(yj)/∂y) i

Simplifying this expression, we get:

curl f = (-z)i + xj + yk

Next, we need to find the divergence of the curl of f, which is given by:

div(curl f) = ∇ · (∇ × f) = ∂(∂(zk)/∂y - ∂(yj)/∂z)/∂x + ∂(∂(yj)/∂x - ∂(xyzi)/∂y)/∂y + ∂(∂(xyzi)/∂z - ∂(zk)/∂x)/∂z

Substituting the values from the curl f expression, we get:

div(curl f) = ∂(-z)/∂x + ∂(x)/∂y + ∂(y)/∂z

Simplifying this expression, we get:

div(curl f) = 0

Multifactor productivity is a measure that assesses the efficiency and effectiveness of a production process by considering the combined contribution of multiple inputs or factors of production. It quantifies the ratio of output to a combination of inputs, such as labor, capital, energy, materials, and other resources utilized in the production process.

To compute the multifactor productivity measure for each week, we need the following information:

1. Labor cost: We know the hourly wage is $16, and each week has 40 hours of work. Therefore, the labor cost for a week can be calculated as $16/hour * 40 hours = $640.

2. Overhead cost: The overhead cost is given as 1.5 times the weekly labor cost. Therefore, the overhead cost for a week is 1.5 * $640 = $960.

3. Material cost: The material cost is given as $9 per pound. We need additional information about the pounds of material used in each week to calculate the material cost.

Once we have the labor cost, overhead cost, and material cost for each week, we can calculate the multifactor productivity measure using the formula:

Multifactor Productivity = Output / (Labor Cost + Overhead Cost + Material Cost).To compute the multifactor productivity measure, we need the following information for each week:

1. Total output (number of chocolate bars produced)

2. Labor cost (total hours worked by employees)

3. Overhead cost (1.5 times the labor cost)

4. Material cost (total pounds of material used)

Let's assume we have data for two weeks:

Week 1:

- Total output: 500 chocolate bars

- Labor cost: 320 hours

- Material cost: 400 pounds

Week 2:

- Total output: 600 chocolate bars

- Labor cost: 400 hours

- Material cost: 500 pounds

First, we need to calculate the labor cost and overhead cost for each week:

Week 1:

- Labor cost = 320 hours * $16/hour = $5,120

- Overhead cost = 1.5 * $5,120 = $7,680

Week 2:

- Labor cost = 400 hours * $16/hour = $6,400

- Overhead cost = 1.5 * $6,400 = $9,600

Next, we calculate the total cost for each week by adding the labor cost, overhead cost, and material cost:

Week 1:

- Total cost = $5,120 (labor cost) + $7,680 (overhead cost) + ($9/pound * 400 pounds) = $5,120 + $7,680 + $3,600 = $16,400

Week 2:

- Total cost = $6,400 (labor cost) + $9,600 (overhead cost) + ($9/pound * 500 pounds) = $6,400 + $9,600 + $4,500 = $20,500

Finally, we can compute the multifactor productivity measure using the formula:

Multifactor Productivity = Total output / Total cost

Week 1:

- Multifactor Productivity = 500 bars / $16,400 = 0.0305 bars/dollar

Week 2:

- Multifactor Productivity = 600 bars / $20,500 = 0.0293 bars/dollar

Answer:

133.33

Step-by-step explanation:

In 133.33 years, the principal amount of $500 at the rate of 1.5% per year will triple.

Simple interest is an interest which is only based on principal amount, it does not imply on yearly interest.

Given that,

The principal amount put in the bank p= $500

The rate of simple interest r= 1.5 %

Amount will be triple, implies that, Interest would be two times of principal.

Interest = 2 x 500 = 1000

To find the time t, when amount gets triple, use simple interest formula

Interest = (p x r x t)/100

1000 = (500 x 1.5 x t)/100

200/1.5 = t

We have,

To arrange the length of the sides of the quadrilateral from longest to shortest, we need to calculate the length of each side of the quadrilateral using the distance formula:

Distance Formula:

If (x1, y1) and (x2, y2) are two points in a plane, then the distance between them is given by:

d = √((x2 - x1)² + (y2 - y1)²)

Using the distance formula, we can calculate the length of each side of the quadrilateral as follows:

AB = √((4 - (-5))² + (5 - 5)²) = 9

BC = √((2 - 4)² + (0 - 5)²) = √(29)

CD = √((-5 - 2)² + (-2 - 0)²) = √(74)

The value of r in terms of x is : r = 100 × (10+x)/(100+x)

Information available from the question:

The volume of water in a certain tank is x percent greater than it was one week ago.

r is the percent of the current volume of water.

Now is x% greater than volume one week ago

=> V now = V week ago (1+x/100)

If r percent of the current volume is removed, the resulting volume will be 90 percent of the volume a week ago

Step-by-step explanation:

First, figure out the measurement of angle 2. Take 180 degrees (the total of the triangle) and subtract 90 (the right angle) and 53 (the given measurement of angle 1). 180-90-53=37      

Angle 2 measures 37 degrees. The measurements of angles 2 and 3 need to equal 180 when added together as they form a straight line, so take the total (180) and subtract the value of angle 2 (37). 180-37=143

Angle 3 measures 143 degrees

A and B have the same elements, the measure of AUB will be equal to the measure of B.

To show that if m*(A) = 0, then m*(AUB) = m*(B), we need to prove the following:
1. If m*(A) = 0, then A is a null set.
2. If A is a null set, then AUB = B.
3. If AUB = B, then m*(AUB) = m*(B).
Let's break down each step:
1. If m*(A) = 0, then A is a null set:
  - By definition, a null set has a measure of 0.
  - Since m*(A) = 0, it implies that A has no elements or its measure is 0.
  - Therefore, A is a null set.
2. If A is a null set, then AUB = B:
  - Since A is a null set, it means that it has no elements or its measure is 0.
  - In set theory, the union of a null set (A) with any set (B) results in B.
  - Therefore, AUB = B.
3. If AUB = B, then m*(AUB) = m*(B):
  - Since AUB = B, it implies that both sets have the same elements.
  - The measure of a set is defined as the sum of the measures of its individual elements.
  - Since A and B have the same elements, the measure of AUB will be equal to the measure of B.
  - Therefore, m*(AUB) = m*(B).
By proving these three steps, we have shown that if m*(A) = 0, then m*(AUB) = m*(B).

The length of the ladder Mr. Jackson will need to buy for his treehouse is approximately 3.7 meters

Step-by-step explanation:

The parameters given in the question are;

The horizontal distance from the point Mr. Jackson has decided to anchor the ladder to the the stilt supporting the tree house = 1.3 meters

The angle of elevation from Mr. Jackson's eye level to the bottom of the treehouse = 56°

The height of Mr. Jackson's eye level from the ground = 1.5 meters

From the question, we can draw the geometry of the ladder attached to the treehouse using Microsoft Visio as shown in the attached diagram

From the diagram, by trigonometric ratios, we have;

tan(56°) = a/1.3

∴ a = 1.3 × tan(56°) ≈ 1.927

By Pythagoras' theorem, we have;

The length of the ladder = √((a + b)² + 1.3²)

From the drawing, b = 1.5 m

Therefore, we have

The length of the ladder = √((1.927 + 1.5)² + 1.3²) ≈ 3.6653

The length of the ladder without rounding = √((1.3 × tan(56°)  + 1.5)² + 1.3²) = 3.66559488352

∴ The length of the ladder given to the nearest tenth of a meter ≈ 3.7 m

The length of the ladder Mr. Jackson will need to buy for his treehouse ≈ 3.7 m.

The diameter of the wheel of a unicycle is 0.7 m. Elaine managed to cycle in 70.4 meters.

A circle's diameter cuts through the centre and extends from edge to edge, in contrast to a circle's radius, which extends from center to edge. Essentially, a circle is divided in half by its diameter.

The circle's diameter is determined by the length of the line drawn through its center and stopping at two locations on its rim.

The radius of a circle is the separation between its center and any point on its edge. The radius is equal to the diameter in half, or 2r = d. A chord is the section of a line that connects two points on a circle.

Given that,

Wheel Diameter = 0.7 m

Wheel Radius (r) = 0.7 m / 2 = 0.35 m

For one rotation of the wheel, the distance travelled = circumference of the wheel.

So, circumference = 2 × π × radius (r)

or, circumference = 2 × π × 0.35

or, circumference = 2.1991148575 m

It is also given that, Elaine tries to ride the unicycle and manages to go in a straight line for 32 full revolutions before falling off.

Thus, distance travelled with 32 full revolutions of the wheel:

Distance = 32 x 2.1991148575 m

Distance in meters = 70.37167544 m

Approximately = 70.4 m
