what is the determinant of the identity matrix I?​

Answers

Answer 1

Answer:

Explanation:

The ith column of an identity matrix is the unit vector ei (the vector whose ith entry is 1 and 0 elsewhere) It follows that the determinant of the identity matrix is 1, and the trace is n. When the identity matrix is the product of two square matrices, the two matrices are said to be the inverse of each other.

Answers

Answer:

The answer is "Option D".

Explanation:

In the given question "(array, 3, 4, key) and (array, 4, 4, key)", the element 'e' to also be searched is concentrated mostly on the right-hand side of the array since it is in the last place. This same middle value is 2 but findMatch(array, mid + 1 high, key) is labeled twice to move the center pointer to its last position, that is, so move that search item's 'e.'

The city of Green Acres is holding an election for mayor. City officials have decided to automate the process of tabulating election returns and have hired your company to develop a piece of software to monitor this process. The city is divided into five precincts. On election day, voters go to their assigned precinct and cast their ballots. All votes cast in a precinct are stored in a data file that is transmitted to a central location for tabulation.

Required:
Develop a program to count the incoming votes at election central.

Answers

Answer:

Explanation:

The following program asks the user to enter the precinct number and then loops to add votes until no more votes need to be added. Then it breaks the loop and creates a file called results to save all of the results for that precinct.

precinct = input("Enter Precinct Number: ")

option1 = 0

option2 = 0

while True:

   choice = input("Enter your vote 1 or 2: ")

   if int(choice) == 1:

       option1 += 1

   else:

       option2 += 1

   endVote = input("Vote again y/n")

   if endVote.lower() != 'y':

       break

f = open("results.txt", "w")

f.write("Precinct " + precinct + ": \nOption 1: " + str(option1) + "\nOption 2: " + str(option2))

What is the effect when one part of a system changes? A. The entire system changes or could stop working. B. The closed-loop system becomes an open-loop system. C. The open-loop system becomes a closed-loop system. D. The larger system is not affected.

Answers

Answer:

c is the answer hope you get it right

The effect when one part of a system changes C. The open-loop system becomes a closed-loop system.

Systemic change is generally understood to require adjustments or transformations in the policies, practices, power dynamics, social norms or mindsets that underlie the societal issue at stake. It often involves the collaboration of a diverse set of players and can take place on a local, national or global level.

How does a systemic change happen?

All systems organize individual pieces into some sort of interrelated whole. Put simply, systemic change occurs when change reaches all or most parts of a system, thus affecting the general behavior of the entire system.

Why is systems change important?

A systems-change approach is more appropriate for problems that are complex, unpredictable, and context-dependent. For example, the challenge of inadequate access to educational opportunities for children from low-income neighborhoods cannot be addressed with a straightforward, logistical fix.

Imagine that you are helping to build a store management system for a fast food restaurant. Given the following lists, write a program that asks the user for a product name. Next, find out if the restaurant sells that item and report the status to the user. Allow the user to continue to inquire about product names until they elect to quit the program.

Answers

Answer:

The program in python is as follows:

def checkstatus(food,foodlists):

   if food in foodlists:

       return "Available"

   else:

       return "Not Available"

foodlists = ["Burger","Spaghetti","Potato","Lasagna","Chicken"]

for i in range(len(foodlists)):

   foodlists[i] = foodlists[i]. lower()

food = input("Food (Q to quit): ").lower()

while food != "q":

   print("Status: ",checkstatus(food,foodlists))

   food = input("Food (Q to quit): ").lower()

Explanation:

The program uses function.

The function is defines here. It accepts as input, a food item and a food list

def checkstatus(food,foodlists):

This check if the food is in the food lists

   if food in foodlists:

Returns available, if true

       return "Available"

Returns Not available, if otherwise

   else:

       return "Not Available"

The main begins here.

The food list is not given in the question. So, I assumed the following list

foodlists = ["Burger","Spaghetti","Potato","Lasagna","Chicken"]

This converts all items of the food list to lowercase

for i in range(len(foodlists)):

   foodlists[i] = foodlists[i]. lower()

Prompt the user for food. When user inputs Q or q, the program exits

food = input("Food (Q to quit): ").lower()

This is repeated until the user quits

while food != "q":

Check and print the status of the food

   print("Status: ",checkstatus(food,foodlists))

Prompt the user for another food

   food = input("Food (Q to quit): ").lower()

b) 2 2 2 2 2
c) 2 4 8 16 32 64 End
d) 2 4 8 16 32

Answers

Answer:

The output of the program is:

2 4 8 16 32 64 End

Explanation:

See attachment for proper presentation of the program

The program uses recursion to determine its operations and outputs.

The function is defined as: myMathFunction(int a, int r, int counter)

It initially gets the following as its input from the main method

a= 1; r = 2; counter = 0

Its operation goes thus:

val = a*r; 1 * 2 = 2

Print val; Prints 2

if (counter > 4) { System.out.print("End"); } : Not true

else { myMathFunction(val, r, counter + 1); }: True

The value of counter is incremented by 1 and the function gets the following values:

a= 2; r = 2; counter = 1

val = a*r; 2 * 2 = 4

Print val; Prints 4

else { myMathFunction(val, r, counter + 1); }: True

The value of counter is incremented by 1 and the function gets the following values:

a= 4; r = 2; counter = 2

val = a*r; 4 * 2 = 8

Print val; Prints 8

else { myMathFunction(val, r, counter + 1); }: True

The value of counter is incremented by 1 and the function gets the following values:

a= 8; r = 2; counter = 3

val = a*r; 8 * 2 = 16

Print val; Prints 16

else { myMathFunction(val, r, counter + 1); }: True

The value of counter is incremented by 1 and the function gets the following values:

a= 16; r = 2; counter = 4

val = a*r; 16 * 2 = 32

Print val; Prints 32

else { myMathFunction(val, r, counter + 1); }: True

The value of counter is incremented by 1 and the function gets the following values:

a= 32; r = 2; counter = 5

val = a*r; 32 * 2 = 64

Print val; Prints 64

if (counter > 4) { System.out.print("End"); } : True

This prints "End"

So; the output of the program is:

2 4 8 16 32 64 End

Write a Python code that takes two sequences CATCGTCCT and CACCGACCG and prints the point mutations found when aligning the two sequences. Tip: you simply need to write a for loop to go over the length of the sequences, pick a letter from each position,and, compare the two sequences position by position for matches and report the mismatches.

Answers

Answer:

Following are the code to the given question:

def match_sequence(s1,s2):#Defining a method match_sequence that accepts two parameters

for l in range(len(s1)):#defining a loop that checks range of s1 value

if(s1[l] != s2[l]): # use if block to match each sequences

print('The sequence does not match at index: ',l+1)#print value with message

s1 = 'CATCGTCCT'#defining a string varible s1

s2 = 'CACCGACCG'#defining a string varible s1

match_sequence(s1,s2)#calling a method that prints its values

Output:

The sequence does not match at index: 3

The sequence does not match at index: 6

The sequence does not match at index: 9

Explanation:

In this code, a method "match_sequence" is declared that takes two string variable "s1 and s2" in its parameters, and inside the method, a loop is declared that checks the range of s1 value and use if block to match each sequence and use a print method that prints it values.

Outside the method, two string variables are declared that holds a string value that passes into the "match_sequence" method and calls it.
