Engineers often measure the ratio of two power measurements in decibels, or dB, which can be calculated as follows: P2 dB = log10 P1 Where P; is the power level being measured, and Pi is some reference power level. Write a function that calculates the level. The function's prototype is as follows: double dBCalculator (double P1, double P2); Then, call dBCalculator from the main function to find the power ratio for the measurements from 1 to 20 Watts, in 2 Watt steps. You can assume that the reference power P1 is 1 Watt.

Write a program that takes as input five numbers and outputs the mean (average) and standard deviation of the numbers. If the numbers are x1,x2,x3,x4,andx5, then the mean is x=(x1+x2+x3+x4+x5)/5 and the standard deviation is: s=(x1x)2+(x2x)2+(x3x)2+(x4x2)+(x5x2)5 Your program must contain at least the following functions: a function that calculates and returns the mean and a function that calculates the standard deviation.

Write a function that asks the user for their birthday month and day and then the function should call a nested function to find out the person’s zodiac sign. Test your program with some user input. Aries: March 21 - April 19 Taurus: April 20 – May 20 Gemini: May 21- June 21 Cancer: June 22- July 22 Leo: July 23 – August 22 Virgo: August 23 – September 22 Libra: September 23 – October 23 Scorpio: October 24 – November 21  Sagittarius: November 22 – December 21 Capricorn: December 22 – January 19 Aquarius: January 20 – February 18 Pisces: February 19 – March 20
In C, write a function that gets two ints a and b. If a>b the function returns a^3 + b^2, and otherwise it returns a^2 + b^3. int square_cube (int a, int b); For example: square_cube (1,2) should return 1 + 8 = 9. square_cube (10, 3) should return 1000 + 9 = 1009. square_cube (2, -1) should return 8 + 1 = 9. square_cube (-2, -1) should return 4 - 1 = 3.
def truth_value(integer): """Convert an integer into a truth value.""" # Convert 0 into False and all other integers, # including 1, into True if integer == 0: truth_value = False else: truth_value = True return truth_value Now, write a function that goes in the opposite direction of the truth_value() function. This new function should convert a truth value into an integer. In particular, True should be converted into 1 and False into 0. Name the new function integer_0_or_1(). All you need to include below is your definition of the function integer_0_or_1(). It will be tested automatically against relevant inputs. So include your function and nothing more.
Write a function that takes one double parameter, and returns a char. The parameter represents a grade, and the char represents the corresponding letter grade. If you pass in 90, the char returned will be ‘A’. If you pass in 58.67, the char returned will be an ‘F’ etc. Use the grading scheme on the syllabus for this course to decide what letter to return.

Write a function MaxMagnitude() with two integer input parameters that returns the largest magnitude value. Use the function in a program that takes two integer inputs, and outputs the largest magnitude value. Ex: If the inputs are: 5 7 the function returns: 7 Ex: If the inputs are: -8 -2 the function returns: -8 Note: The function does not just return the largest value, which for -8 -2 would be -2. Though not necessary, you may use the absolute-value built-in math function. #include <iostream>using namespace std; void MaxMagnitude(int userVal1, int userVal2) {if (abs(userVal1) > abs(userVal2)) {return userVal1;}else if (abs(userVal2) > abs(userVal1)) {return userVal2;}}/* Define your function here */ int main() { int userVal1;int userVal2;cin >> userVal1 >> userVal2;/* Type your code here. Your code must call the function. */ cout << MaxMagnitude(userVal1, userVal2) << endl;/* Type your code here */ return 0;} Please help me with this problem using…
