Write a Python program that verifies the formula with the help of the Python Math module. Note that the trigonometric functions in the module act on the angles in radians. Your program should perform the following steps 3 times:_____.
1. Pick a random number between 0 and 180 degrees representing an angle in degrees, say Dangle
2. Convert the angle from degrees to radians, say Rangle
3. Use the Math module to find and print the values of sin(Rangle) and cos(Rangle), and
4. Compute and print the value of the above expression: sin^2(Rangle) + cos^2(Rangle).
You can then visually verify if the result printed is 1 (or close to it).
Hint: angle_in_radians = (angle_in_degrees * Pi)/180
Answer:
Written in Python
import math
import random
Dangle = random.randint(0,181)
pi = 22/7
Rangle = Dangle * pi/180
Rsin = math.sin(Rangle)
Rcos = math.cos(Rangle)
Result = Rsin**2 + Rcos**2
print("Result = "+str(Result))
Explanation:
The next two lines import math and random library respectively
import math
import random
This line generates a random integer between 0 and 180
Dangle = random.randint(0,181)
This line initializes pi to 22/7
pi = 22/7
This line converts angle to radians
Rangle = Dangle * pi/180
The next two lines calculate the sin and cosine of the angle in radians
Rsin = math.sin(Rangle)
Rcos = math.cos(Rangle)
This line implements sin^2 theta + cos^2 theta
Result = Rsin**2 + Rcos**2
This line prints the required Result
print("Result = "+str(Result))
PLEASE HURRY!!
Look at the image below!

the weight variable is an integer and the input is 115.6. Integers cannot have decimals, therefore, the output is 115.

g Unlike when you create a String, when you create a StringBuilder, you must use the keyword ____________.
Answer:
Unlike when you create a String, when you create a StringBuilder, you must use the keyword new
Explanation:
Strings are used in programming which also opens the way for StringBuilder to be used too. In javascript, for instance, variables are useful for storing data, We have "Let" and "const" variables. Const variables cannot be changed after they’re created. The data stored are in types an example is a string. Strings allow one to write a value and store the result in a variable.
For example, using the dot operator, when you:
console.log('love'.length); // Prints 4
Note that console.log() allows the computer to evaluate the expression inside the parentheses and print that result to the console.
.length prints 4 as the result. This shows how the string has a property that stores the number of characters in that string.
StringBuilder with the keyword "new" is used when we want to change or modify data property stored in a string.

Write a program that will print out statistics for eight coin tosses. The user will input either an "h" for heads or a "t" for tails for the eight tosses. The program will then print out the total number and percentages of heads and tails. Use the increment operator to increment the number of tosses as each toss is input. For example, a possible sample dialog might be: For each coin toss enter either ‘h’ for heads or ‘t’ for tails. First toss: h Second toss: t Third toss: t Fourth toss: h Fifth toss: t Sixth toss: h Seventh toss: t Eighth toss: t Number of heads: 3 Number of tails: 5 Percent heads: 37.5 Percent tails: 62.5
Answer:
Written in Python
head = 0
tail = 0
for i in range(1,9):
print("Toss "+str(i)+": ")
toss = input()
if(toss == 'h'):
head = head + 1
else:
tail = tail + 1
print("Number of head: "+str(head))
print("Number of tail: "+str(tail))
print("Percent head: "+str(head * 100/8))
print("Percent tail: "+str(tail * 100/8))
Explanation:
The next two lines initialize head and tail to 0, respectively
head = 0
tail = 0
The following is an iteration for 1 to 8
for i in range(1,9):
print("Toss "+str(i)+": ")
toss = input() This line gets user input
if(toss == 'h'): This line checks if input is h
head = head + 1
else: This line checks otherwise
tail = tail + 1
The next two lines print the number of heads and tails respectively
print("Number of head: "+str(head))
print("Number of tail: "+str(tail))
The next two lines print the percentage of heads and tails respectively
print("Percent head: "+str(head * 100/8))
print("Percent tail: "+str(tail * 100/8))

The algorithm S(A, n, i) selects all the j-th smallest elements (with j ≤ i) from an array A of n elements, by using linearselect to select each of the j-th smallest elements (with j ≤ i). Clearly, one could also implement S alternatively as T(A, n, i), which first sort A (on average-case and on worstcase, the sorting takes time O(n log n) using mergesort) and then select the first i elements. Please compare the average-case complexities of the two algorithms; i.e., For the average-case complexities, under what conditions (on the choices for i), S is better than T or vice versa
Answer:
Follows are the solution to this question:
Explanation:
In the linear selected algorithms scans the given field sequentially but instead calculates the fixed amount by crossing the items throughout the list since they are displayed. Take into consideration the various chosen algorithm:
S(A, n, i) Algorithm:
In array B, copy array A items.
To save results, construct an array C of height.
Start Loop j = 0 to i-1.
Determine array B's lowest value.
In array C, also save the minimum value.
Delete from array B the minimum value.
Back the C array.
Analysis of runtime:
In i iterations, the external loop is used, although i have to compute the number of small lots.
This internal loop should run and calculate the minimum variable, whereby n is the input array length at the most values of n.
Its cumulative runtime is equal to O(in)+C =
O(in). All remaining operations are done at a precise rate.
The combine type technique requires that division concept to
sort the sorted array either in or upwards backward order.
Follow the appropriate method using merge type to
select the shortest items of a certain list.
T (A, n, i) algorithm:
In B array, copy array A elements.
To save the output, build a C array of sizes.
Using merge form in an increasing order to sort all items of the B list.
Start the loop j= 0 to i-1.
Save A[j] value in C[j].
Return array C,
return array C.
Analysis of run time:
The combined function requires O (n log n) to arrange a size n list.
Its number of samples in the process to construct the resulting sequence becomes equal to i since i is the minimum number of elements to also be calculated. All remaining transaction is performed in continuous time.
The time to work is O (n log n) + O i + C = O (n log n). The time needed.
The complexities of the following algorithms are similar:
Scenario 1: S is stronger than to the T-algorithm
Consider the number for smallest elements to also be calculated or even the I value is significantly smaller than the number of array elements. Let i = 2 and n = 16.
Its algorithm S requires O(in) time for both the calculation of a result, who in this case is equivalent to (2 16).
If algorithm T finds the initiative of O (n log n), who in this case is equivalent to (16 logs 16) = (16 4).
The S method, therefore, operates better than that of the T algorithm, if another I value exceeds the log n value.
Scenario 2: Algorithm T is much more successful that algorithm S
Evaluate if the number of components which must be calculated is smaller or if the value of I is comparable with that of the items inside the array.
Let the I = 12 quality and n = 16 value. Its S method applies O(in) time, and in this, the situation is just like (12 16).
Hence, the algorithm T performs better than the algorithm S when the value of i is greater than the value of the log n.
An example of an access control is a: Multiple Choice Check digit. Password. Test facility. Read only memory.
Answer:
B. Password
Explanation:
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication is like an access control, ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
An example of an access control is a password because it is typically a basic and fundamental front-line defense mechanism against an unauthorized use of data or cyber attacks from hackers.
