Answers
To find the second principal minor of the Hessian matrix for the function f(x, y) = 160x - 3x^2 - 3xy - 2y^2 + 120y - 18, follow these steps:
Step 1: Find the partial derivatives of the function with respect to x and y.
f_x = ∂f/∂x = 160 - 6x - 3y
f_y = ∂f/∂y = -3x - 4y + 120
Step 2: Compute the second-order partial derivatives.
f_xx = ∂²f/∂x² = -6
f_xy = ∂²f/∂x∂y = -3
f_yx = ∂²f/∂y∂x = -3
f_yy = ∂²f/∂y² = -4
Step 3: Form the Hessian matrix using the second-order partial derivatives.
H = | f_xx f_xy |
| f_yx f_yy |
H = | -6 -3 |
| -3 -4 |
Step 4: Find the second principal minor by computing the determinant of the Hessian matrix.
H_21 = f_yy = -4
So, the second principal minor of the Hessian matrix for the given function is H_21 = -4.
What is the Hessian matrix used for?
Hessian matrices are a type of second order derivative-based mathematical construction. They are frequently employed in data science and machine learning techniques to optimize a function of interest.

The sales of Sherwin-Williams paint in different regional markets depends on several input variables. One variable that partially drives selling price, which in turn affects sales, is the cost to get the product to market. When other input variables are held constant, sales can be modeled as
when it costs x dollars to get a gallon of paint to market, data from 0 ≤ x ≤ 2.
(Source: Based on data from Sherwin-Williams as reported in J. McGuigan et al., Managerial Economics, Stamford, CT: Cengage, 2008)
a. How many gallons of paint are sold when it costs 75 cents for a gallon to reach the market?
b. How quickly is sales changing when x = 0.75?
Answers
a.18.5 gallons of paint are sold when it costs $0.75 for a gallon of paint to reach the market
b. when x = 0.75, the rate at which the sales of paint is changing is -23.
a.Based on the data from Sherwin-Williams as reported in J. McGuigan et al., Managerial Economics, Stamford, CT: Cengage, 2008, the sales of paint are given byS(x) = 8 + 16x − 25x2.
In this scenario, the value of x is 0.75 as the cost to get a gallon of paint to the market is $0.75 per gallon.
Then, the number of gallons of paint that are sold is given by substituting x = 0.75 in the sales equation.
S(x = 0.75) = 8 + 16(0.75) − 25(0.75)2= 18.5
Therefore, 18.5 gallons of paint are sold when it costs $0.75 for a gallon of paint to reach the market
b. The rate at which the sales of paint is changing at x = 0.75 is given by the derivative of the sales equation with respect to x.
dS/dx = 16 − 50x.
Substituting x = 0.75 in the above expression gives:dS/dx (x = 0.75) = 16 − 50(0.75) = −23.
Therefore, when x = 0.75, the rate at which the sales of paint is changing is -23.

Because of compensation, travel expenses, and booth rental, fixed costs for a trade show are expected to be $15,990. The booth will be open 39 hours during the trade show. Ms. Ortega also plans to add a new product line, ProOffice, which will cost $184 per package. She will continue to sell the existing product, EZRecords, which costs $105 per package. Ms. Garcia believes that the salesperson will spend approximately 29 hours selling EZRecords and 10 hours marketing ProOffice. Required Determine the estimated total cost and cost per unit of each product, assuming that the salesperson is able to sell 76 units of EZRecords and 53 units of ProOffice. Determine the estimated total cost and cost per unit of each product, assuming that the salesperson is able to sell 200 units of EZRecords and 99 units of ProOffice.
Answers
Answer and Explanation:
The computation of the estimated total cost & the cost per unit is given below:
For 76 units & 52 units
For EZRecords
Total cost = Fixed cost + variable cost
where
Fixed cost = $15,990 × 29 hours ÷ 39 hours
= $11,890
And, the variable cost is
= 76 units × $105
= $7,980
So, the total cost is
= $11,890 + $7,980
= $19,870
And, the cost per unit is
= $19,870 ÷ 76 units
= $261.45
For Pro office
Total cost = Fixed cost + variable cost
where
Fixed cost = $15,990 × 10 hours ÷ 39 hours
= $4,100
And, the variable cost is
= 53 units × $184
= $9,752
So, the total cost is
= $4,100 + $9,752
= $13,852
And, the cost per unit is
= $13,850 ÷ 53 units
= $261.35
For 200 units & 99 units
For EZRecords
Total cost = Fixed cost + variable cost
where
Fixed cost = $15,990 × 29 hours ÷ 39 hours
= $11,890
And, the variable cost is
= 200 units × $105
= $21,000
So, the total cost is
= $11,890 + $21,000
= $31,890
And, the cost per unit is
= $31,890 ÷ 200 units
= $159.45
For Pro office
Total cost = Fixed cost + variable cost
where
Fixed cost = $15,990 × 10 hours ÷ 39 hours
= $4,100
And, the variable cost is
= 99 units × $184
= $18,216
So, the total cost is
= $4,100 + $18,216
= $22,316
And, the cost per unit is
= $22,316 ÷ 99 units
= $225.41

a. Ijtihad is not the main practice in solving issues in Islamic finance nowadays. It is a process of reasoning, but other practices are also used. b. The regulatory framework in the Malaysian Islamic financial system includes the Shariah Advisory Council, Central Bank, and Securities Commission, ensuring compliance and protection.
a. Ijtihad is the main practice in solving issues in Islamic finance nowadays.False. Although Ijtihad is a process of systematic reasoning to reveal the rule of law, it is not the main practice in solving issues in Islamic finance nowadays. Ijtihad is a traditional Islamic legal term, which means independent reasoning or the utmost effort an individual puts forth to interpret the primary sources of Islamic law, the Quran, and the Sunnah, to deduce rules that can be applied in contemporary times. Islamic finance, on the other hand, is the application of Islamic principles to financial transactions.
This means that Ijtihad can be used to interpret Shariah principles and apply them to contemporary financial transactions, but it is not the only practice used in solving issues in Islamic finance nowadays. For example, Shariah boards and scholars play a crucial role in the development and regulation of Islamic financial products and services, as they provide guidance on Shariah compliance and approve financial products and services before they are offered to the public.
b. Regulatory framework used in Islamic financial system in Malaysia. The regulatory framework used in the Islamic financial system in Malaysia is based on Shariah principles and is designed to promote the development and growth of the industry while ensuring the protection of the interests of stakeholders. The regulatory framework consists of several key components, including the Shariah Advisory Council, the Central Bank of Malaysia, and the Securities Commission of Malaysia.
The Shariah Advisory Council is responsible for providing guidance on Shariah compliance and approving financial products and services before they are offered to the public. The Central Bank of Malaysia, also known as Bank Negara Malaysia, is responsible for regulating and supervising Islamic banks and financial institutions. The Securities Commission of Malaysia is responsible for regulating and supervising Islamic capital markets and Islamic fund management activities.
In addition to these components, the regulatory framework also includes various laws and regulations that govern the Islamic financial industry, such as the Islamic Financial Services Act 2013 and the Islamic Capital Markets and Services Act 2012. These laws and regulations provide a legal framework for the industry and ensure that Islamic financial institutions and products comply with Shariah principles.

Answer : Monopolistic competition
Answer:
Monopolistic Competition
Explanation:
In a monopolistic competitive market, there are large numbers of sellers who do not sell identical products instead they sell differential products. They compete with each other at a competitive price. The products could be differentiated in many ways including quality, style, location and even brand name. Since they compete at a competitive price, if there is a substantial rise in the price of any of the products, the buyers could quickly shift from one product to another. The most crucial factor behind product differentiation is because of geographical factors. Under a monopolistic competitive market, the sellers do not have any influence over customer loyalty and limited control over the price.

Answers
In January, the family received a free water allowance of 15 kilolitres, and any additional water usage beyond this allowance would be subject to a charge of $2 per kilolitre.
In January, the family received a free water allowance of 15 kilolitres. Since January has 31 days, this means that they were entitled to use an average of approximately 0.48 kilolitres per day for free. If the family used less than or equal to 15 kilolitres of water during the month of January, they would not have to pay anything extra.
However, if they used more than their free allowance, they would be charged for the excess usage. To calculate the amount the family had to pay for their excess usage, the difference between their total usage and their free allowance must be determined.
For example, if the family used 18 kilolitres of water during the month, they exceeded their free allowance by 3 kilolitres. If the cost of water is $2 per kilolitre, the family would have to pay $6 for their excess usage.
