- (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.Problem 4.

Deal or No Deal?by CodeChum Admin When I was a kid, I used to watch this TV game show, Deal or No Deal? In the game, there are different brief cases, each labeled with a number. Inside each brief case is an amount in Pesos and the goal is to guess which briefcase contains the smallest amount. In this program, instead of just finding the smallest amount, your task is to ask the user for an integer input and print the values in the array smaller than the inputted integer. Instructions: In the code editor, you are provided with an array with 100 elements.Your task is to ask the user for an integer input and then print all the elements in the array whose value is lesser than the inputted integer.Input 1. Inputted integer Output Enter value: 6132450351503022244
- -) Write a complete C++ program that takes the users' weight and their lifestyle as an input and recommends the number of calories they should take per day. Your program needs to take users' weight as an integer value and their lifestyle as a character that shows if they are active (a) or sedentary (inactive) (s). Your program then calculates the number of calories by multiplying the users' weight with the activity factor. If the person is sedentary, that person's activity factor is 13. If the person is active, that person's activity factor is 15. Sample Run Please enter your weight: 60 Do you have an active (a) or sedentary (s) lifestyle? s The recommended number of calories: 780C++ Programming Exercise: The population of town A is less than the population of town B. However, the population of town A is growing faster than the population of town B. Write a program that prompts the user to enter the population and growth rate of each town. The program outputs after how many years the population of town A will be greater than or equal to the population of town B and the populations of both the towns at that time. (A sample input is: Population of town A = 5,000, growth rate of town A = 4%, population of town B = 8,000, and growth rate of town B = 2%.)[Python (py3)] Displayed below is a code for matrix addition. However, there is an error that should be fixed in the code. The error in the code below is if the number of rows of the matrix is not equal to the number of columns of the same matrix, matrix addition will not be performed. This should not be the case so please fix this error. The only requirement for matrices addition is that the dimension of Matrix A is equal to the dimension of Matrix B, regardless if the number of rows of Matrix A and Matrix B is equal to the number of columns of Matrix A and Matrix B, respectively (see sample input and output below).Please resolve the error in the code below such that Matrix A and Matrix B can be added if the dimension of Matrix A is equal to the dimension of Matrix B. PLEASE do not just copy the code below and use it as the answer itself. I've encountered such case many times. Please modify the code. When the dimension of Matrix A is not equal to the dimension of Matrix B, print…

Rolling two dice produces a number between 2 and 12 with a binomial distribution. In this lab you will simulate a number of dice rolls and graph the number of occurrences of each value. 1) Create a function called rollDie() that takes no parameters, and returns a random value between 1 and 6. Do not seed the random number generator in this function. int rollDie() 2) Create a function called initArray() that takes a data array and the size of the array as parameters and fills each element with the summed results of rolling two dice. Do not assume that the data array has been initialized. void initArray(int data[], int size) 3) Create a function called sortArray() that takes an array and the size of the array as parameters, and sorts the array using the sediment sort. void sortArray(int data[], int size) The sediment sort works as follows: start with the second element in the array…
