Oldham Inc.'s State M tax is $135,000, and State N tax is $210,000.

To calculate Oldham Inc.'s State M and State N taxes, we need to determine the apportionment percentage and apply it to the before-tax income. First, let's calculate the apportionment factors for each state: Apportionment Factor for State M = (Sales in State M + Payroll in State M + Property in State M) / (Total Sales + Total Payroll + Total Property). Apportionment Factor for State N = (Sales in State N + Payroll in State N + Property in State N) / (Total Sales + Total Payroll + Total Property). Given that State N double-weights the sales factor, we can calculate the weighted sales factor for State N: Weighted Sales Factor for State N = (2 * Sales in State N) / (Total Sales + Total Payroll + Total Property). Next, we can calculate the apportionment percentage for each state: Apportionment Percentage for State M = Apportionment Factor for State M. Apportionment Percentage for State N = Weighted Sales Factor for State N. Now, we can calculate the State M and State N taxes: State M Tax = Before-Tax Income * Apportionment Percentage for State M * State M Tax Rate. State N Tax = Before-Tax Income * Apportionment Percentage for State N * State N Tax Rate. Given the information provided, the State M tax rate is 4.5% and the State N tax rate is 7%. Calculating the State M tax: State M Tax = $3,000,000 * Apportionment Percentage for State M * 4.5%. Calculating the State N tax: State N Tax = $3,000,000 * Apportionment Percentage for State N * 7%.

1. The Recovery Manager employs checkpointing, which is the process of periodically saving the state of the database to stable storage. 2. The difference between stable storage and disk is that stable storage provides a higher level of reliability and durability guarantees than disks do.

1. The Recovery Manager ensures atomicity and durability of transactions through two main techniques: logging and checkpointing. For atomicity, it maintains a log that records all changes made to the database during a transaction. In case of a failure, it uses this log to undo any incomplete transactions, thus ensuring that either all or none of the operations in a transaction are executed.

To ensure durability, the Recovery Manager employs checkpointing, which is the process of periodically saving the state of the database to stable storage. After a successful checkpoint, the changes made by committed transactions are guaranteed to be permanent, even in case of a system failure.

2. The primary difference between stable storage and disk is related to data reliability. Stable storage is a conceptual storage medium that guarantees data durability by employing techniques such as redundancy and error correction. It ensures that once data is written, it is preserved even in the event of system failures or crashes. On the other hand, a disk is a physical storage device that can store data but does not inherently provide the same level of durability as stable storage. Disks are prone to data loss due to hardware failures or other issues. In the context of a database system, stable storage is often implemented using multiple disks and other fault-tolerant mechanisms to provide the required level of data reliability.

The rate of change of total profit with respect to time is 189,000 dollars per hour.

To find the rate of change of total profit with respect to time, we need to use the formula:

Profit = Revenue - Cost

where Revenue is the product of the selling price and the quantity sold, and Cost is the sum of all expenses incurred in producing the goods.

In this case, the revenue function is given by:

R(x) = r(x) * x = (80x - 0.5x²) * x = 80x² - 0.5x³

And the cost function is given by:

C(x) = c(x) = 30x³

Therefore, the profit function is:

P(x) = R(x) - C(x) = (80x² - 0.5x³) - 30x³ = -0.5x³ + 80x²

To find the rate of change of total profit with respect to time, we need to take the derivative of the profit function with respect to time:

dP/dt = dP/dx * dx/dt

where dx/dt is given as 90.

Taking the derivative of the profit function with respect to x, we get:

dP/dx = -1.5x² + 160x

Plugging in x = 30, we get:

dP/dx = -1.5(30)² + 160(30) = 2100

Therefore, the rate of change of total profit with respect to time is:

dP/dt = dP/dx * dx/dt = 2100 * 90 = 189,000 dollars per hour.

This means that the total profit is increasing at a rate of $189,000 per hour when x = 30 and the rate of change of the quantity sold is 90 units per hour.

The profit-maximizing quantity in this perfectly competitive market is 52 units.

The profit-maximizing quantity in a perfectly competitive market. Given the cost function c = 540 + 7q^2 and price P = $725, let's follow these steps:

Step 1: Determine the total revenue (TR) function. Since price is constant, TR = P * q = 725q.

Step 2: Calculate the profit (π) function by subtracting the total cost (TC) from total revenue (TR): π = TR - TC = 725q - (540 + 7q^2).

Step 3: To maximize profit, we need to find the quantity (q) where the derivative of the profit function (π') is equal to zero. So, take the derivative of the profit function with respect to q: π' = d(π)/dq = 725 - 14q.

Step 4: Set π' equal to zero and solve for q: 0 = 725 - 14q => q = 725 / 14 => q = 51.79.

Since the profit-maximizing quantity should be a whole number, we will round it to the nearest whole number: q = 52.

The correct answer is a) cell wall structure. The different staining properties of Gram-positive and Gram-negative prokaryotes are primarily due to differences in their cell wall structures.

The Gram staining technique is used to differentiate bacteria into two major groups: Gram-positive and Gram-negative. The differential staining is based on the differences in the cell wall structure of these bacteria.

Gram-positive bacteria have a thick peptidoglycan layer in their cell walls, which retains the crystal violet dye during the staining process. This results in the bacteria appearing purple under a microscope after staining. The peptidoglycan layer in Gram-positive bacteria is also responsible for providing structural integrity and protection to the cell.

In contrast, Gram-negative bacteria have a thinner peptidoglycan layer and an outer membrane containing lipopolysaccharides. The thinner peptidoglycan layer in Gram-negative bacteria does not retain the crystal violet dye as effectively. Instead, the outer membrane of Gram-negative bacteria is stained by the counterstain, safranin, which imparts a pink color to these bacteria.

Therefore, the different staining properties between Gram-positive and Gram-negative bacteria are primarily due to the variations in their cell wall structures. Gram-positive bacteria have a thick peptidoglycan layer, while Gram-negative bacteria have a thinner peptidoglycan layer and an additional outer membrane.

When a company buys back its own shares, the shares are called "treasury shares."

When a company repurchases its own shares from the open market, those shares are referred to as "treasury shares." Treasury shares are essentially the company's own stock that has been bought back and is held by the company itself, rather than being held by shareholders or available for public trading.

Treasury shares are typically held by the company for various purposes, such as future reissuance or cancellation. By buying back its own shares, a company reduces the number of outstanding shares in the market, which can have several implications. It may signal that the company believes its shares are undervalued, and it can also help increase earnings per share by distributing profits over a smaller number of shares.

While treasury shares are not counted as outstanding shares, they still represent ownership in the company. However, they do not have voting rights and do not receive dividends. Companies may decide to sell treasury shares back into the market at a later time or retire them altogether, effectively reducing the overall equity base of the company.

By adding 100 pounds of nitrogen at 25 cents per pound and achieving a similar yield response, the overall cost of production would increase by $25. However, the benefits would depend on various factors such as crop type, soil condition, and environmental considerations.

The cost of adding 100 pounds of nitrogen at 25 cents per pound would amount to $25. If this additional nitrogen application resulted in a yield response comparable to the current nitrogen application, the cost of production would increase by that amount. However, the actual benefits of this investment would depend on several factors.

Firstly, the specific crop being grown plays a crucial role in determining the yield response to nitrogen. Different crops have varying nutrient requirements and respond differently to nitrogen application. Secondly, the existing soil condition and nutrient levels also influence the effectiveness of additional nitrogen. If the soil is already rich in nitrogen, the response to additional application may be minimal. Thirdly, environmental considerations must be taken into account. Excessive nitrogen usage can lead to environmental issues such as water pollution or greenhouse gas emissions.

Therefore, while adding 100 pounds of nitrogen at 25 cents per pound may result in a similar yield response, it is essential to consider the specific crop, soil condition, and environmental factors to determine the true cost and benefits of this investment.

According to the question As the total volume of activity changes:

- The total of variable costs changes: Variable costs are directly tied to the level of activity. As the volume of activity increases or decreases, the total variable costs will also change proportionally.

- The total of fixed costs remains the same: Fixed costs are expenses that do not vary with the level of activity. They stay constant regardless of the volume of activity.

- Fixed costs per unit stay the same: Since fixed costs do not change with the level of activity, the fixed costs per unit will remain constant. As the volume of activity increases or decreases, the fixed costs are spread over a larger or smaller number of units, but the fixed cost per unit remains the same.

- Variable costs per unit change: Variable costs are costs that vary with the level of activity. Therefore, as the volume of activity changes, the variable costs per unit will also change. For example, if the volume of activity increases, the variable costs per unit may decrease as economies of scale are achieved.

In summary, the total of variable costs and variable costs per unit change with the total volume of activity, while fixed costs remain the same in total but may change on a per-unit basis.
