Price Ceiling: A price ceiling is a government-imposed maximum price set below the equilibrium market price.

It is intended to protect consumers by keeping prices low and affordable for certain goods or services.

Price ceilings are often implemented during times of market shortages or to control inflation.

Price Floor: A price floor is a government-imposed minimum price set above the equilibrium market price.

It is intended to protect producers by ensuring they receive a certain level of income for their goods or services.

Price floors are often used in agricultural markets or to establish minimum wage laws.

Value-based Pricing vs. Cost-based Pricing: Both value-based pricing and cost-based pricing approaches have their advantages and disadvantages.

Value-based pricing focuses on determining the perceived value of a product or service to customers and pricing it accordingly.

This approach considers the benefits and value that customers derive from the product and sets the price based on what customers are willing to pay.

Value-based pricing allows for higher profit margins and takes into account customer preferences and willingness to pay.

Cost-based pricing, on the other hand, sets prices based on the production costs and desired profit margin.

It involves calculating the total cost of producing the product and adding a markup to determine the selling price.

Cost-based pricing is more straightforward and easier to implement, as it relies on the actual costs incurred in producing the product.

The length of a side of the hexagon or square is - 16 units

The length of a side of the hexagon or square = x

The perimeter of the square = 4 × lengths of its side

                                               = 4x

The perimeter of the hexagon = 6 × lengths of its side

                                                  = 6x

According to the question,

                                           4x + 32 = 6x

                                       ⇒ 6x - 4x = 32

                                       ⇒  2x = 32

                                       ⇒  x = 16

So, the length of a side of the hexagon or square is - 16 units.

The length of the base and height of the triangle are 19 ft and 15 ft respectively.

Let the height of the triangle be 'h' ft. Then, the base of the triangle would be (h + 4) ft. Using the formula for the area of a triangle, the length of the base and the height of the triangle are to be found.

The formula for the area of a triangle is given by;

Area of a triangle = (1/2) x base x height142.5 = (1/2) x (h + 4) x h142.5 = (h² + 4h) / 2

Multiplying both sides by 2, we get;285 = h² + 4h

Solving the quadratic equation:285 = h² + 4h0 = h² + 4h - 285h = (-4 + √(4² - 4(1)(-285))) / 2 or h = (-4 - √(4² - 4(1)(-285))) / 2h = 15 or h = -19.

Let's ignore the negative value of h as length and height cannot be negative.

So, the height of the triangle is 15 ft. Length of the base = height + 4

Length of the base = 15 + 4Length of the base = 19 ft.

Therefore, the length of the base and height of the triangle are 19 ft and 15 ft respectively.

The two fractions with denominators of 2 and 6 that add up to 19/3 are 3/6 and 29/3, respectively.

First, let's break down what that mixed number means in terms of fractions. 6 1/3 is the same as 19/3.

Now, we need to find two fractions with different denominators that add up to 19/3. One way to do this is to use a common denominator. To find a common denominator, we need to find the least common multiple (LCM) of the two denominators.

Let's say we want to find two fractions that add up to 19/3, with denominators of 2 and 6. The LCM of 2 and 6 is 6. So, we can rewrite the fractions with a denominator of 6:

1/2 = 3/6

x/6

Now we need to find the value of x that makes the sum of the fractions equal to 19/3:

3/6 + x/6 = 19/3

To solve for x, we can multiply both sides by 6:

3 + x = 38/3

Then, we can subtract 3 from both sides:

x = 29/3

The formulated Linear Program aims to minimize the objective function, which is the sum of production and inventory costs minus the revenue from selling the end-of-period inventory at month 4.

In this problem, we need to determine the optimal production and inventory levels over the four-month period to minimize costs and maximize revenue. We can formulate this as a linear programming problem with the following decision variables:

Let x1, x2, x3, x4 represent the production quantities for months 1, 2, 3, and 4, respectively.

Let y1, y2, y3, y4 represent the end-of-month inventory levels for months 1, 2, 3, and 4, respectively.

The objective function we want to minimize is:

Minimize: (5x1 + 8x2 + 4x3 + 7x4) + (2y1 + 2y2 + 2y3) - (15y4)

Subject to the following constraints:

1. Initial inventory: y1 = 15 (given)

2. Production capacity constraints:

  x1 <= 90 (month 1 capacity)

  x2 <= 75 (month 2 capacity)

  x3 <= 80 (month 3 capacity)

  x4 <= 50 (month 4 capacity)

3. Inventory balance equations:

  y1 + x1 - 50 = y2 (month 1)

  y2 + x2 - 65 = y3 (month 2)

  y3 + x3 - 100 = y4 (month 3)

  y4 + x4 - 70 = 0 (month 4, no carryover inventory)

4. Non-negativity constraints:

  x1, x2, x3, x4, y1, y2, y3, y4 ≥ 0

Answer:

m∠3 = 78

Step-by-step explanation:

Okay, since a triangle has 3 sides, we only need to find the measure of m∠3.

A triangle is made up of 180 degrees, so we can make an equation with 180 as what the equation is equal to.

Since m∠1 = 70, and m∠2 = 32, we will add those together with a variable x,

70+32+x=180

70 plus 32 is 102.

102+x=180

To get 102 to the other side we need to do the opposite of addition, which is subtraction.

180-102=78

So the answer is 78.

Answer:

50π cm²/s

Step-by-step explanation:

Area of the circle A = πd²/4

Rate at which the area is changing with time is expressed as;

dA/dt = dA/dd*dd/dt

dd/dt is the rate at which the diameter is changing with time

dd/dt = 5cm/sec

dA/dd = 2πd/4

dA/dd = πd/2

Given that d = 20cm

dA/dt = dA/dd*dd/dt

dA/dt = πd/2*5

dA/dt = 20π/2 *5

dA/dd = 10π * 5

dA/dd = 50π cm²/s

Hence the area is changing at the rate of  50π cm²/s

The ponderal index cannot be computed without the value of the constant "a" in the formula. Therefore, the ponderal index for a person who is 76 inches tall and weighs 192 pounds cannot be determined.

To compute the ponderal index, we need the formula and the value of the constant "a."

a) The formula for the ponderal index is given as I = a, where I represents the ponderal index and a is a constant. However, the value of the constant "a" is missing in the provided information. Without knowing the value of "a," we cannot compute the ponderal index for a person who is 76 inches tall and weighs 192 pounds.

The value of Exterior Angle B in the polygon is equal to 102°.

What is Polygon?

A polygon is a two-dimensional closed object made up of line segments (not curves). Polygon is made up of two words: poly (which means numerous) and gon (which means shape) (means sides). A closed figure requires at least three line segments connected end to end.

We are given eith the exterior angles

∠A = 8x°

∠B = 9x + 3°

∠C = 5x + 4°

∠D = 9x + 5°

And using the property that sum of exterior angles of a polygon is 360°

We can find the value of x

8x + 9x + 3 + 5x + 4 + 9x +5 = 360

31x + 12 = 360

31x = 348

x = 11

Answer:

B

Step-by-step explanation:

So we have the system of equations:

\(x-2y=3\\2x-3y=9\)

To solve, we can use the substitution method. First, add 2y to both sides in the first equation:

\(x=3+2y\)

Now, substitute this into the secon equation:

\(2(3+2y)-3y=9\)

Distribute the 2:

\(6+4y-3y=9\)

Combine like terms:

\(6+y=9\)

Subtract 6 from both sides:

\(y=3\)

So, the value of y is 3.

Substitute this back into the original equation to find x. Thus:

\(x=3+2(3)\)

Multiply:

\(x=3+6\)

Add:

\(x=9\)
