The date 8/3/2021 is stored in cell c1. What function is used to extract just 3?.
The date supplied as a serial number in cell c1 is converted to the day of the month using the Microsoft Excel formula =DAY(C1).
Dates are kept in Microsoft Excel as consecutive serial numbers so that computations may be made with them. Because January 1, 2008 is 39,448 days after January 1, 1900, it is serial number 39448 instead of the normal number 1, which is assigned on January 1, 1900.
Regardless of the display format for the supplied date value, the values returned by the YEAR, MONTH, and DAY functions will all be Gregorian values.
In Microsoft Excel, the DAY function returns the day of a date as a serial number. An integer in the range of 1 and 31 is used to specify the day.
The serial number in DAY(serial number) represents the date of the day you're looking for. Dates must be entered either directly or as the output of other formulas or functions, such as the DATE function. For the 23rd day of May 2008, for instance, use DATE(2008,5,23).

write a program which prompts the user for a celsius temperature, convert the temperature to fahrenheit, and print out the converted temperature.
print("——OR——") Input ("Temperature value in degree Celsius:"), celsius 2 = float) Celsius 2 = (Fahrenheit 2 * 9/5) + 32; print the result.
The user's input is taken. Enter the temperature in celsius by typing it into the input box. Fahrenheit is equivalent to (celsius multiplied by 1.8) + 32 print(str(celsius)+ "A degree in Celsius is equal to a " + str(fahrenheit)+ " degree in Fahrenheit. The change from C to F is therefore 100/180, or 5/9. It is 180/100 or 9/5 from F to C. As a result, the conversion yields °F = °C (9/5) + 32. As a result, the equation for changing from the Celsius to Fahrenheit scale becomes °F = °C (9/5) + 32.

Recurrence relations can be resolved using the Recursion Tree Method. Recursive trees are created using this method from a recurrence relation.
Each node reflects the expense incurred at different recursive levels. The overall cost is calculated by adding the costs from each level.
20 nodes at level 0 are equal to one.
21 + 2 Equals number of nodes at level 1.
Number of nodes at level 2log10/9(n), which is equal to nlog10/9 (2)
nlog10/9(2) x T(1) = nlog10/9(2) x 1 = nlog10/9 Cost of subproblems at level log2(n) (last level) (2)
Step 4: Add up all of the levels' costs in the recursive tree.
T(n) = n times (number of levels - 1) plus the cost of the last level.
= log10/9(n) times + (nlog10/9(2)) = n + n + n + —-

because volume-based allocation rates assign more cost to high-volume products, low-volume products are often undercosted.
The allocation of factory overhead to goods based on the quantity of production resources used is known as traditional costing.
What is Traditional Costing?According to the quantity of resources used in production, traditional costing divides factory overhead among products. With this approach, overhead is typically calculated based on either the number of hours of direct labor or the number of machine hours used. Traditional costing has the drawback that factory overhead may be substantially higher than the basis of allocation, causing a small change in the volume of resources consumed to result in a large change in the amount of overhead applied. This is a problem that is especially frequent in factories with high levels of automation, where direct labor is almost nonexistent and factory overhead is quite high.For instance, a conventional costing analysis might determine that factory overhead should be charged to products at a rate of $500 per direct labor hour. As a result, if there is a slight change in the production process that increases direct labor by one hour, the cost of the product has just increased by $500 of overhead. Given that there isn't always a direct correlation between the volume of production resources and factory overhead, such a significant change in applied overhead makes no sense.When overhead is simply applied to the quantity of produced units for the purpose of valuing ending inventory, traditional costing still serves financial statement reporting well. From the perspective of management decision-making, there are no repercussions.
