(Python) Numerous engineering and scientific applications require finding solutions to a set of equations. Ex: 8x + 7y = 38 and 3x - 5y = -1 have a solution x = 3, y = 2. Given integer coefficients of two linear equations with variables x and y, use brute force to find an integer solution for x and y in the range -10 to 10.
Ex: If the input is:
8 7 38 3 -5 -1
Then the output is:
x = 3 , y = 2
Use this brute force approach:
For every value of x from -10 to 10 For every value of y from -10 to 10 Check if the current x and y satisfy both equations. If so, output the solution, and finish.
Ex: If no solution is found, output:
"There is no solution"
You can assume the two equations have no more than one solution.
''' Read in first equation, ax + by = c '''a = int(input())b = int(input())c = int(input())
''' Read in second equation, dx + ey = f '''d = int(input())e = int(input())f = int(input())
Language: C++ (Apartment problem) A real estate office handles , say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit?
Write a program that prompts the user to enter:
The total number of units.
The rent to occupy all the units.
The increase in rent that results in a vacant unit.
Amount to maintain rented unit.
The program then outputs the number of units to be rented to maximize the profit.
Note: Please include the pseudocode
(Comparing Integers) Write a program that prompts the user to enter the edges of a triangle and compares them. If all edges are equal, display Equilateral Triangle; if only two edges are equal, display Isosceles Triangle and if none of the edges are equal, display Scalene Triangle. Use c++ program.

(Guess the Number) Write a C program that plays the game of "guess the number" as fol- lows: Your program chooses the number to be guessed by selecting an integer at random in the range 1 to 1000. The program then types: 5.32 I have a number between 1 and 1000. Can you guess my number? Please type your first guess. The player then types a first guess. The program responds with one of the following: 1. Excellent! You guessed the number! Would you like to play again (y or n)? 2. Too low. Try again. 3. Too high. Try again. If the player's guess is incorrect, your program should loop until the player finally gets the number right. Your program should keep telling the player Too high or Too low to help the player “zero in" on the correct answer. [Note: The searching technique employed in this problem is called binary search.

- Computer Science Please help You went camping overnight but forgot to take with you a heater and need to make one using a dc battery of V0 and spare electrical wires of different lengths and resistivity. The battery has lead with the resistance of Rw. Please obtain the formula for the joule heat power and plot it as a function of RH ( in MATLAB) and in comparison to the resistance of the connecting leads, Rw. (Note: express RH = x Rw, where x is the effective ratio; vary x and plot Pmax vs. x). and Find the heating power if the heater is made out of superconducting metal. Will this heater work and why?!

- (C PROGRAMMING ONLY!) 3. Pet Loverby CodeChum Admin One of the easiest ways to make a pet lover happy is to give them very many pets! My friend, Jhelian is a pet lover and for her 21st birthday, I'm planning to give her very many Dogs. It's very timely because my pet dog just gave birth to a lot of cuties! So I don't really need to buy. All I need is to just give these cute little fur babies to her. Instructions: In the code editor, you are provided with the definition of a struct Dog. This struct needs a character value for its gender, which could either be 'm' for a male Dog or 'f' for a female Dog.Furthermore, an array of Dogs has already been created an each of their genders has been set. Then, on line 16, a call to the function giveDogs() was made where the dogs array was passed.Your task is to implement this giveDogs() function which has the following details:Return type - voidName - giveDogsParametersa pointer/holder of a Dogs arraysize of the Dogs arrayDescription - loops…arrow_forward(Electrical eng.) a. The voltage gain of an amplifier is given by this formula: voltagegain=[275 23 2 +0.5 f 2 ]n f is the frequency in Hz. n is the number of stages in the amplifier. Using this formula, write, compile, and run a C++ program to determine the value of the voltage gain for a four-stage amplifier operating at a frequency of 120 Hz. Your program should produce the following display: At a frequency of xxxxx hertz, the voltage gain is yyyyy Your program should replace xxxxx with the frequency and yyyyy with the voltage gain. b. Manually check the value your program produces. After verifying that your program is working correctly, modify it to determine the voltage gain of a 12-stage amplifier operating at a frequency of 9500 Hz.arrow_forward(Count positive and negative numbers and compute the average of numbers) Write a c++ program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the average as a floating-point number. Here is a sample run:Enter an integer, the input ends if it is 0: 1 2 -1 3 0The number of positives is 3The number of negatives is 1The total is 5.0The average is 1.25arrow_forward

The function main should ask the user to enter three grades and then pass these values to the course_average function. This function should also display a message to the user in the format below. For example, if the user entered 100, 90 and 95 the message would be:The average of 100 , 90 and 95 is 95arrow_forward(The conical paper cup problem) You have been given the contract for making little conical cups that come with bottled water. These cups are to be made from a circular waxed paper of 4 inches in radius by removing a sector of length x (see Figure 5-4 below). By closing the remaining part of the circle, a conical cup is made. Your objective is to remove the sector so that the cup is of maximum volume. Instructions Write a program that prompts the user to enter the radius of the circular waxed paper. The program should then output: The length of the removed sector so that the resulting cup is of maximum volume The maximum volume Calculate your answer to two decimal places.Use 3.141592654 for PIarrow_forward
