The trigonometry book says: sin^2(t) + cos^2(t) = 1 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).
Answer:
If you open your python-3 console and execute the following .py code you will have the following output. (Inputing 20 e.g)
Write the angles in degrees: 20
radian angles is: 0.3490658503988659
cosene( 0.3490658503988659 ) = 0.9396926207859084
sine( 0.3490658503988659 ) = 0.3420201433256687
sin^2( 0.3490658503988659 ) + cos^2( 0.3490658503988659 ) = 1.0
Explanation:
Code
import math
for i in range(1,4):
angle = int(input('Write the angles in degrees: '))
#mat library better works with radians
angle_radians = (angle*math.pi)/180
#print output
print('radian angles is: ',angle_radians)
print('cosene(',angle_radians,') = ',math.cos(angle_radians))
print('sine(',angle_radians,') = ',math.sin(angle_radians))
res = (math.sin(angle_radians))**2 + (math.cos(angle_radians))**2
print('sin^2(',angle_radians,') + cos^2(',angle_radians,') = ',res)

Assume a 64KB cache with four-word block size (a word is 4 bytes) and a 32-bit address. If a block has 28 tag bits, what is the type of this cache
Answer:
Fully associative
Explanation:
Fully associative cache is a type of cache in which after retrieving the data from memory, it subsequently allows data to be deposited in the available but unused cache block. This is to ensure that the storage of cache is done without forcing each memory address into one specific block.
Given the following
address = 32 bits,
tag = 28 bits, as a block is 4 words that are, 4x4 bytes,
offset = 4 bits, which equates to index = 0 bits.
Hence, it can be concluded that the type of cache is FULLY ASSOCIATIVE.

Answer:
Continuous Improvement
Explanation:
Continuous Improvement is a set of processes many companies use to evaluate and improve their overall operations on an ongoing basis. Usability testing Continuous Improvement Analytics System implementation.
What is Continuous Improvement?W. Edwards Deming used the phrase "continuous improvement" to refer to general processes of improvement and to embrace "discontinuous" improvements, or many diverse ways addressing various topics.
A subset of continuous improvement, with a more narrow focus on linear, incremental change inside an already-existing process, is continuous improvement.
Some practitioners also believe that statistical process control techniques are more closely related to continuous improvement. Constant improvement, often known as continuous improvement, is the continued enhancement of goods, services, or procedures through both small-scale and significant advancements.
Therefore, Continuous Improvement is a set of processes many companies use to evaluate and improve their overall operations on an ongoing basis. Usability testing Continuous Improvement Analytics System implementation.

Create a flowchart designing a solution to the following problem:
Anna has saved $50,000 for a down payment on a house. Your algorithm will ask Anna how much the house she would like to purchase costs (verify that the entered value is at least $10,000 and no more than $1,000,000.) If Anna’s savings is at least 20% of the house cost, provide a message that tells her that she will not have to pay for mortgage insurance. If, however her savings is less than 20%, but more than 10% provide a message that she can still purchase the home but will have to have the insurance. If unfortunately her savings are 10% or less of the home cost provide a message that she is not eligible to purchase the home and tell her the maximum home price she can afford.

Assume that at time 5 no system resources are being used except for the processor and memory. Now consider the following events:
At time 5: P1 executes a command to read from disk unit 3.
At time 15: P5’s time slice expires.
At time 18: P7 executes a command to write to disk unit 3.
At time 20: P3 executes a command to read from disk unit 2.
At time 24: P5 executes a command to write to disk unit 3.
At time 28: P5 is swapped out.
At time 33: An interrupt occurs from disk unit 2: P3’s read is complete.
At time 36: An interrupt occurs from disk unit 3: P1’s read is complete.
At time 38: P8 terminates.
At time 40: An interrupt occurs from disk unit 3: P5’s write is complete.
At time 44: P5 is swapped back in.
At time 48: An interrupt occurs from disk unit 3: P7’s write is complete.

Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Ex: If the input is 20.0 3.1599, the output is: 1.57995 7.89975 63.198 Note: Small expression differences can yield small floating-point output differences due to computer rounding. Ex: (a + b)/3.0 is the same as a/3.0 + b/3.0 but output may differ slightly. Because our system tests programs by comparing output, please obey the following when writing your expression for this problem. First use the dollars/gallon and miles/gallon values to calculate the dollars/mile. Then use the dollars/mile value to determine the cost per 10, 50, and 400 miles. Note: Real per-mile cost would also include maintenance and depreciation.
Answer:
The Following are the code to this question:
def cost(miles, milesPerGallon, dollarsPerGallon):##defining a method cost that accepts three parameter
return miles / milesPerGallon * dollarsPerGallon# calculate cost and return it value
milesPerGallon = float(input('Enter miles/Gallon value: '))#defining variable milesPerGallon for user input
dollarsPerGallon = float(input('Enter dollars/ Gallon value: '))#defining variable dollarsPerGallon for user input
print('{:.5f}'.format(cost(10, milesPerGallon, dollarsPerGallon)))#call method and print its value
print('{:.5f}'.format(cost(50, milesPerGallon, dollarsPerGallon)))#call method and print its value
print('{:.3f}'.format(cost(400, milesPerGallon, dollarsPerGallon)))#call method and print its value
Output:
Enter miles/Gallon value: 20.0
Enter dollars/ Gallon value: 3.1599
1.57995
7.89975
63.198
Explanation:
In the above-given code, a method "cost" is defined, that accepts three value "miles, milesPerGallon, and dollarsPerGallon" in its parameter, and use the return keyword for calculating and return its value.
In the next step, two variable "milesPerGallon, and dollarsPerGallon" is declared, that use the input method with float keyword for input floating-point value.
After input value, it uses a print method with different miles values, which are "10,50, and 400", and input value to pass in cost method to call and print its return value.
The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0, which is no wind, up to 12, which is a hurricane. The following script first generates a random force value. Then, it prints a message regarding what type of wind that force represents, using a switch statement. You are to rewrite this switch statement as one nested 150 CHAPTER 4: Selection Statements if-else statement that accomplishes exactly the same thing. You may use else and/or elseif clauses.
ranforce = randi([0, 12]); switch ranforce case 0 disp('There is no wind') case {1,2,3,4,5,6} disp('There is a breeze') case {7,8,9} disp('This is a gale') case {10,11} disp('It is a storm') case 12 disp('Hello, Hurricane!') end
Answer:
ranforce = randi([0, 12]);
if (ranforce == 0)
disp('There is no wind')
else if(ranforce>0 && ranforce <7)
disp('There is a breeze')
else if(ranforce>6 && ranforce <10)
disp('This is a gale')
else if(ranforce>9 && ranforce <12)
disp('It is a storm')
else if(ranforce==12)
disp('Hello, Hurricane!')
end
Explanation:
Replace all switch case statements with if and else if statements.
An instance is:
case {7,8,9}
is replaced with
else if(ranforce>9 && ranforce <12)
All other disp statements remain unchanged
