Chapter 5.3, Problem 2E

(Physics) a. Design, write, compile, and run a C++ program to calculate the elapsed time it takes to make a 183.67-mile trip. This is the formula for computing elapsed time: elapsedtime=totaldistance/averagespeed The average speed during the trip is 58 mph. b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the elapsed time it takes to make a 372-mile trip at an average speed of 67 mph.

(Practice) Determine the values of the following integer expressions: a.3+46f.202/( 6+3)b.34/6+6g.( 202)/6+3c.23/128/4h.( 202)/( 6+3)d.10( 1+73)i.5020e.202/6+3j.( 10+3)4

(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.

Identify and fix any memory bugs you find in the following program:

Produce the following program.

-Convert SES variable to a factor and assign the value labels “low”, ”middle” and “high” to the 3 levels of thevariable. Then -Define the variables complic, comorb, depressi, diabetes as factors. For all these factors, a zero means “no” and a 1 means “yes”. Assign these value labels through the function factor() and check the change using str()

c) It is desired to compute the some of the first 10 terms of the series                    14k3 -20k2 +5k, k= 1, 2, 3            Write a MATLAB program that can calculate the sum                                                                                                                                                                    d)  Write a MATLAB program that determine the number of elements in all Numbers         bigger than 100

State whether the following are true or false. If the answer is false, explain why.c) The expression (x > y && a < b) is true if either x > y is true or a < b is true.

(Physics) a. The weight of an object on Earth is a measurement of the downward force onth e object caused by Earth’s gravity. The formula for this force is determined by using Newton’s Second Law: F=MAeFistheobjectsweight.Mistheobjectsmass.AeistheaccelerationcausedbyEarthsgravity( 32.2ft/se c 2 =9.82m/ s 2 ). Given this information, design, write, compile, and run a C++ program to calculate the weight in lbf of a person having a mass of 4 lbm. Verify the result produced by your program with a hand calculation. b. After verifying that your program is working correctly, use it to determine the weight, on Earth, of a person having a mass of 3.2 lbm.
