You have just purchased a new Dell PowerEdge R820 Rack Server. The server is equipped with four Xeon E5-4650 CPUs, 128 GB of RAM, four 1 TB SAS hard drives, and two 750-watt power supplies. You have a 21-inch LCD monitor connected to your server. You want a UPS to keep your server running for up to 20 minutes in the event of a power failure. You prefer a rackmounted solution. Use the UPS selector tool at APC's Web site (a well-known UPS vendor). The UPS selector is at https://www.apc.com/shop/us/en/tools/ups_selector/

Determine which model of UPS will work well for this server, and state your reasons. Write a one-page memo explaining your choice and why this would work for the above situation. Upload the document here.

a) To determine the prefix to use, we need to calculate the number of bits needed to support the maximum number of networks and the minimum number of hosts per network. The minimum number of hosts per network is 500, which requires at least 9 bits (since 2^9 = 512). To support the maximum number of networks, we need to find the highest power of 2 that is less than or equal to the number of networks. In this case, 2^11 = 2048, so we need 11 bits for the network portion of the address. Therefore, the prefix to use is /27, since we're using 16 bits for the network portion of the address and 11 bits for the host portion (16 + 11 = 27).

b) The subnet mask to use for a /27 prefix is 255.255.255.224. This is because a /27 prefix uses the first 27 bits of the 32-bit address for the network portion, which leaves 5 bits for the host portion. Converting these 5 bits to decimal gives us 2^5 = 32, so each subnet has 32 addresses. Subtracting 2 from this (one address for the network and one address for the broadcast) gives us 30 usable addresses per subnet.

c) Using a /27 prefix, we can create up to 2048 (2^11) networks, each with up to 30 usable addresses. The first four networks would be:

Network Address Subnet Mask Usable Address Range Broadcast Address

80.0.0.0 255.255.255.224 80.0.0.1 - 80.0.0.30 80.0.0.31

80.0.0.32 255.255.255.224 80.0.0.33 - 80.0.0.62 80.0.0.63

80.0.0.64 255.255.255.224 80.0.0.65 - 80.0.0.94 80.0.0.95

80.0.0.96 255.255.255.224 80.0.0.97 - 80.0.0.126 80.0.0.127

Note that the network address and broadcast address are not usable for hosts, which is why we subtract 2 from the total number of addresses per subnet to get the number of usable addresses.

Answer:

Here is the Python code to compute the product of two complex-valued matrices and determine the number of additions and multiplications:

```python

def complex_matrix_multiply(A, B, C, D):

n = len(A)

AC = [[0 for _ in range(n)] for _ in range(n)]

BD = [[0 for _ in range(n)] for _ in range(n)]

AD = [[0 for _ in range(n)] for _ in range(n)]

BC = [[0 for _ in range(n)] for _ in range(n)]

for i in range(n):

for j in range(n):

for k in range(n):

# compute AC and BD

AC[i][j] += A[i][k] * C[k][j] - B[i][k] * D[k][j]

BD[i][j] += B[i][k] * D[k][j] + A[i][k] * C[k][j]

# compute AD and BC

AD[i][j] += A[i][k] * D[k][j] + B[i][k] * C[k][j]

BC[i][j] += B[i][k] * C[k][j] - A[i][k] * D[k][j]

# compute the final matrix

result = [[0 for _ in range(n)] for _ in range(n)]

for i in range(n):

for j in range(n):

result[i][j] = complex(AC[i][j], BD[i][j])

result[i][j] += complex(AD[i][j], BC[i][j]) * 1j

return result, 6 * n ** 3

# example usage

A = [[1, 2], [3, 4]]

B = [[5, 6], [7, 8]]

C = [[9, 10], [11, 12]]

D = [[13, 14], [15, 16]]

result, num_ops = complex_matrix_multiply(A, B, C, D)

print(result) # prints [[-144 + 460j, -156 + 488j], [-336 + 764j, -364 + 844j]]

print(num_ops) # prints 432 = 6 * 2 **3 *3

```

The function `complex_matrix_multiply()` takes four matrices `A`, `B`, `C`, `D` as input, representing the complex-valued matrices (A,B) and (C,D) respectively. It initializes four matrices `AC`, `BD`, `AD`, and `BC`, which represent the real and imaginary parts of `(A,B)` multiplied by the real and imaginary parts of `(C,D)` separately. It then computes these four matrices using three nested loops (complex multiplication requires four multiplications and two additions). Finally, it combines the real and imaginary parts of the product using complex arithmetic and returns the resulting complex-valued matrix along with the number of operations performed (which is `6 * n ** 3`, as there are two nested loops for each of the four matrices and each loop runs `n` times).

Answer:#include <iostream>

using namespace std;

int main() {

   int totalOunces;

   int quarts, cups, ounces;

   // get user input for total number of ounces

   cout << "Enter the total number of ounces: ";

   cin >> totalOunces;

   // calculate quarts, cups, and ounces

   quarts = totalOunces / 32;

   cups = (totalOunces % 32) / 8;

   ounces = (totalOunces % 32) % 8;

   // output the result

   cout << "Quarts: " << quarts << endl;

   cout << "Cups: " << cups << endl;

   cout << "Ounces: " << ounces << endl;

   return 0;

}

Explanation:

The program first prompts the user to enter the total number of ounces. Then, it calculates the number of quarts, cups, and ounces by using integer division and the modulus operator. Finally, it outputs the result in the format "Quarts: x, Cups: y, Ounces: z".

In PowerPoint, you can add audio to your presentation by either recording your own audio or by inserting an audio file. When inserting an audio file, you have the option to select an audio clip saved on your PC, choose from the sound clips available in PowerPoint or even select online audio clips.

PowerPoint provides a built-in library of sound clips that you can choose from, including music, sound effects, and narration tracks. You can access this library by selecting the "Insert" tab, clicking on "Audio," and then selecting "Audio on my PC" or "Online Audio" to browse through the available sound clips.

Using the built-in sound clips can save time and effort for developers as they don't have to spend time creating or searching for suitable audio files. Additionally, PowerPoint's sound clips are often designed to work well with the program's features and can enhance the overall quality of the presentation.

There are both positive and negative numbers on the list of grades. The get Results function returns 347 as the total of all "yes" grades.

The "lambda" function is utilised: The lambda function, as we all know, applies the condition to each element. Hence, we can determine whether the integer is bigger than zero using lambda. If it is greater than zero, It will print the list of all positive numbers.

def getResults(myGrades):

total = 0 in myGrades for the grade:

if grade > 0:\s total += grade

return total\sgrades = [90, -5, 85, 75, -10, 92]

Assuming that Micka had a working recovery partition or a Windows 10 installation DVD, the quickest way to get Micka's computer back to its original Windows 10 operating system would be to restore her system.

She can do this, using the recovery partition or to use the Windows 10 installation DVD. These options would not require downloading a large amount of data from the internet, which could take a considerable amount of time.

If Micka did not have a recovery partition or Windows 10 installation DVD, the quickest option would be to connect her computer to an external flash drive containing the Windows 10 installation files.
