(General math) a. Write a C++ program to calculate and display the value of the slope of the line connecting two points with the coordinates (3,7) and (8,12). Use the fact that the slope between two points with the coordinates (x1,y1)and(x2,y2)is(y2y1)/(x2x1). b. How do you know the result your program produced is correct? c. After verifying the output your program produces, modify it to determine the slope of the line connecting the points (2,10) and (12,6). d. What do you think will happen if you use the points (2,3) and (2,4), which results in a division by zero? How do you think this situation can be handled? e. If your program doesn’t already do so, change its output to this: The value of the slope is xxx.xx The xxx.xx denotes placing the calculated value in a field wide enough for three places to the left of the decimal point and two places to the right of it.
(General math) If a 20-foot ladder is placed on the side of a building at an 85-degree angle, as shown in Figure 3.11, the height at which the ladder touches the building can be calculated as height=20sin85. Calculate this height by hand, and then write, compile, and run a C++ program that determines and displays the value of the height. After verifying that your program works correctly, use it to determine the height of a 25-foot ladder placed at an angle of 85 degrees.
Consider the simple electric circuit above. Write a C program that calculates the current through each resistor. The code must use a constant for the voltage and arrays for the resistor and current values. The program prints each current value for each resistor on a new line in the format: "I1 = x.xx", etc. Ohm's Law states: I=V/R Complete the following C program using the code provided to match the correct lines of code in the correct order to create the C program. //Line 1 //Line 2 //Line 3//Line 4//Line 5 //Line 6//Line 7//Line 8//Line9//Line 10 -//Line 1 -//Line 2 -//Line 3 -//Line 4 -//Line 5 -//Line 6 -//Line 7 -//Line 8 -//Line 9 -//Line 10 1. #include <stdio.h> 2. printf("I%d = %.2f\n", i+1, currArray[i]); 3. void main(char argc, char **argv) 4. currArray[i] = (float)VOLTAGE/resistArray[i]; 5. float currArray[4], resistArray[4] = {10, 20, 30, 40}; 6. for (int i = 0; i < 4; i++) ; 7. int currArray[4], resistArray[4] = {10, 20, 30, 40}; 8. while…

(Electrical eng.) The amplification of electronic circuits is measured in units of decibels, which is calculated as the following: 10LOG(Po/Pi) Po is the power of the output signal, and Pi is the power of the input signal. Using this formula, write, compile, and run a C++ program to calculate and display the decibel amplification, in which the output power is 50 times the input power. Verify your program’s result by doing a hand calculation. After verifying that your program is working correctly, use it to determine the amplification of a circuit, where output power is 4.639 watts and input power is 1 watt.
(General math) a. Write, compile, and run a C++ program to compute and display the value of the second-order polynomial ax2+bx+c for any user-entered values of the coefficients a, b, c, and the variable x. Have your program display a message to inform users what the program does, and then display suitable prompts to alert users to enter the data. (Hint: Use a prompt such as Enter the coefficient of the x-squared term:.) b. Check the result of your program written for Exercise 7a by using the following test data: Testdataset1:a=0,b=0,c=22,x=56Testdataset2:a=0,b=22,c=0,x=2Testdataset3:a=22,b=0,c=0,x=2Testdataset4:a=2,b=4,c=5,x=2 After finishing your verification, use your program to complete the following chart
(General math) a. Design, write, compile, and run a C++ program that calculates and displays the area of a triangle, such as the one in Figure 2.18, with a base of 1 in and a height of 1.5 in. The area is given by this formula: Area=12(base)(height) b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the area of a two-dimensional triangle with a base of 3.5 in and a height of 1.45 in.

I am needing help with the following prgramming question. Write a program in C++, using case statements, that mimics a calculator. The program should take as input two integers and the operation to be performed. It should then output the numbers, the operator, and the result. For division, if the denominator is zero, output an appropriate message. Some sample outputs are as follow: 3 + 4 = 713 * 5 = 65
