The values of x  and y in the geometric progression are 10 and 20

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

5, x, y, and 40

To calculate the values of x and y, we have

x/5 = 40/y

Cross multiply

So, we have

xy = 200

Set x = 10

So, we have

10y = 200

This gives

y = 20

So, we have

10/5 = 40/20 = 2 --- true

Hence, x is 10 and y is 20

By evaluating the function related to the second derivative f''(x) = - 25 · sin 5x is equal to f(π / 5) = (14π - 50) / 25.

In this question we find the definition of the second derivative of a function, this function must be found by integrals and initial values. First, write the entire function:

f''(x) = - 25 · sin 5x

Second, determine the first derivative:

f'(x) = (1 / 5) · cos 5x + C₁

f(0) = (1 / 5) · cos 0 + C₁

3 = 1 / 5 + C₁

C₁ = 14 / 5

f'(x) = (1 / 5) · cos 5x + 14 / 5

Third, determine the function:

f(x) = (1 / 25) · sin 5x + (14 / 5) · x + C₂

f(0) = (1 / 25) · sin 0 + (14 / 5) · 0 + C₂

- 2 = (1 / 25) · sin 0 + (14 / 5) · 0 + C₂

- 2 = C₂

f(x) = (1 / 25) · sin 5x + (14 / 5) · x - 2

Fourth, evaluate the function:

f(π / 5) = (1 / 25) · sin π + (14 / 5) · (π / 5) - 2

f(π / 5) = 14π / 25 - 2

f(π / 5) = (14π - 50) / 25

Answer:

Step-by-step explanation:

If the large Jar is $4.10 for 540g

and  small jar  $2.81 for 360 g

You need to show how much it cost for 1 g,so you can compare how much it cost per gram. You would divide the total cost by the grams to see how much it is for 1 g.

Large jar.   $4.10/540 = $.0076  for 1 gram

Small Jar.   $2.81/360 =$.0078 for 1 gram

Because the large jar is cheaper to buy per gram, the large jar is the best value for the money.

The radius of the cylindrical cup is 6 centimeters.

A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.

The volume of a cylinder is expressed as;

V = π × r² × h

Where r is radius of the circular base, h is height and π is constant pi ( π = 3.14 )

Given that the volume of the cylindrical cup is 1356.48 cubic centimeters and the height is 12 cm.

We can substitute these values into the formula and solve for the radius:

V = π × r² × h

r = √( V / (πh) )

r = √( 1356.48 / ( 3.14 × 12) )

r = 6 cm

Therefore, the radius is 6cm.

The machine's purchasing cost is $309,210.

The acquisition cost of the machine is the total cost incurred by the firm to purchase and put the machine into service.

To determine the acquisition cost of the machine, we need to add up all the costs listed in the question.

Invoice price = $299,000

Applicable sales tax = $2,100

Freight paid = $1,160

Cost of insurance coverage = $1,025

Installation costs = $1,900

Testing and adjusting costs = $1,375

Repair of damages caused by the firm's employees = $1,450

Prepaid maintenance contract = $1,200

Total acquisition cost = Invoice price + Sales tax + Freight paid + Cost of insurance coverage + Installation costs + Testing and adjusting costs + Repair of damages caused by the firm's employees + Prepaid maintenance contract

Total acquisition cost = $299,000 + $2,100 + $1,160 + $1,025 + $1,900 + $1,375 + $1,450 + $1,200

The total charge is the product of the multiplication of the unit rate by the total kilowatt-hours used by the customer plus the fixed rate.

Multiplication operation is one of the four basic mathematical operations, including addition, subtraction, and division.

Multiplication involves the multiplicand, the multiplier, and the product.

Fixed charge = $5.10

Variable charge per kilowatt-hour = 5.747 cents ($0.05747)

To find a composite number, we find the factors of the given number. The best way to determine a composite number is to do a divisibility test. The divisibility test helps us determine if the number is prime or composite. Divisibility means that one number is divided completely (without remainder) by another number.

The time it takes (1/x) + (1/(x + 5)) + (1/(4x + 20))

​

From the question,

Marla takes 5 hours more than Tom: M = T + 5

Bob takes 4 times as long as Marla: B = 4M

work is inversely proportional to the time hence

Tom: 1/T

Marla: 1/M

Bob: 1/B

When we express this,

Marla: 1/(T + 5)

Bob: 1/(4*(T + 5))

We would have to solve for the total work in a given hour

= (1/T) + (1/(T + 5)) + (1/(4*(T + 5))

In one hour, Tom cаn clеan 1/х оf thе building, Mаrlа cаn clеan 1/(x + 5) оf thе building, and Вob cаn clеan 1/(4х + 20) оf thе building.

then 1/T = 1/x

1/(T + 5) = 1/(x + 5)

1/(4*(T + 5)) = 1/(4x + 20)

A price-setter company, which has considerable market power, is more likely to use cost-plus pricing methods. This method ascertains the price of a product by determining the cost of production and then adding a certain amount for profit. Hence, this strategy ensures that the company covers all costs and makes a profit on each sale.

A price-setter company, which has significant market power, is likely to use more cost-plus pricing methods. In a cost-plus pricing method, the company sets the price of a product by determining the cost of production and then adding a specific amount or percentage as profit. This pricing strategy is straightforward and ensures that all costs are covered and a profit is made on each sale. It offers stability and predictability, which is desirable for a price-setter company with substantial control over the market.

On the other hand, target costing and target pricing methods involve setting a price first and then figuring out how to meet that price with production. These methodologies are typically used in more competitive industries, where companies don't have as much power to set their own prices.

However, a price-setter company, assuming it's not in a perfectly competitive market, has the power to set the price without having to intensely consider competitors' prices or customers' price sensitivity, therefore, it may use cost-plus pricing methods more.

Two write the equation, you need the slope and the y-intercept.  We have the slope ([tex]\frac{-3}{8}[/tex]).  We know need to find the y-intercept.

We will use the m or slope of [tex]\frac{-3}{8}[/tex], x value of -3 from the point (-3,-6)and the y value of -6 from the point (-3,-6)

y = mx + b

-6 = [tex]\frac{-3}{8}[/tex]([tex]\frac{-3}{1)}[/tex]) + b

-6 = [tex]\frac{9}{8}[/tex] + b  Subtract [tex]\frac{9}{8}[/tex] from both sides

[tex]\frac{-6}{1 }[/tex] - [tex]\frac{9}{8}[/tex] = [tex]\frac{9}{8}[/tex] - [tex]\frac{9}{8}[/tex] + b  Use the common denominator of 8

[tex]\frac{-48}{8}[/tex] - [tex]\frac{9}{8}[/tex] = b

[tex]\frac{-57}{8}[/tex] = b
