inches in that many feet. 11. Math Quiz Write a program that gives simple math quizzes. The program should display two random numbers that are to be added, such as: 247 + 129 The program should allow the student to enter the answer. If the answer is correct, a mes- sage of congratulations should be displayed. If the answer is incorrect, a message showing the correct answer should be displayed. 12. Maximum of Two Values Write a function named max that accepts two integer values as arguments and returns the value that is the greater of the two. For example, if 7 and 12 are passed as arguments to the function, the function should return 12. Use the function in a program that prompts the user to enter two integer values. The program should display the value that is the greater of the two. 13. Falling Distance When an object is falling because of gravity, the following formula can be used to deter- mine the distance the object falls in a specific time period: d = 1/2gt² The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the amount of time, in seconds, that the object has been falling. an obiect's

(Physics) Buoyancy is the upward force a liquid exerts on a submerged object, as shown in Figure 6.9. The buoyancy force is given by this formula: B=pgV Bisthebuoyancyforce( lbforN).isthefluiddensity( slug/f t 3 orkg/ m 3 ).gistheaccelerationcausedbygravity( 32.2ft/se c 2 or9.8m/ s 2 ).Vistheobjectsvolume( f t 3 or m 3 ). a. Using this formula, write a function named buoyantForce(double ro, double vol, int units) that accepts a fluid density, the volume of an object placed in the fluid, and the units to be used(1=U.S.Customaryunits,2=metricunits), and returns the buoyancy force exerted on the object. b. Include the function written for Exercise 6a in a working C++ program, and use your program to complete the following chart:
4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }

The base width of the pyramid is determined by a character the user enters. If the user enters the letter o, the following pyramid will be printed. It can be assumed that the screen width is 80 characters. a aba abcba abcdcba abcdedcba abcdefedcba abcdefgfedcba abcdefghgfedcba abcdefghihgfedcba abcdefghijihgfedcba abcdefghijkjihgfedcba abcdefghijklkjihgfedcba abcdefghijklmlkjihgfedcba abcdefghijklmnmlkjihgfedcba abcdefghijklmnonmlkjihgfedcba
A bank charges $10 per month, plus the following check fees for a commercial checking account: $0.10 each for less than 20 checks $0.08 each for 20 through 39 checks $0.06 each for 40 through 59 checks $0.04 each for 60 or more checks Write a function BankCharges() that allows the user to enter the number of checks written and computes and displays the bank’s service fees for the month. All checks for the month are assigned the same charge, based on the total number of checks written during the month. Use the following test data to determine whether the application is calculating properly. In each case, the customer is charged only a single rate, based on the total number of checks. Your solution should clearly show the function. Customer Number of Checks Bank Charges Nancy 15 Lilian 25 Arianna 45 Ben 75

FizzBuzz Interview Question Create a function that takes a number as an argument and returns "Fizz", "Buzz" or "FizzBuzz". If the number is a multiple of 3 the output should be "Fizz". If the number given is a multiple of 5, the output should be "Buzz". If the number given is a multiple of both 3 and 5, the output should be "FizzBuzz". If the number is not a multiple of either 3 or 5, the number should be output on its own as shown in the examples below. The output should always be a string even if it is not a multiple of 3 or 5. Examples fizz_buzz (3) "Fizz" fizz_buzz (5) → "Buzz fizz_buzz (15) "FizzBuzz" fizz_buzz (4) "4" 11
Related to R code. Question: Write a function called temp_categorizer that takes one argument ‘temperature’ and returns the following: - a value of “hot” if temperature is greater or equal to 90 - a value of "warm" if temperature is greater than 60 but less than 90 - a value of "cold" if temperature is more than 32 but less than 60 - a value of "freezing" if temperature is 32 or below And also Use the following vector for problem number : sentence <- c("Learning", "loops", "in", "R", "is", "not", "that", "bad") Create a loop that: loops over the range of possible word lengths displays a message detailing the words that match the length For example: at length 8, the loop should state that the word "Learning" has 8 letters Hints: Use the function nchar() which gives the number of letters in each word. • Example: try nchar(sentence) min() and max() may help you specify a range
Coin Toss Write a function named coinToss that simulates the tossing of a coin. When you call the function, it should generate a random number in the range of 1 through 2. If the random number is 1, the function should display "heads". If the random number is 2, the function should display "tails". Demonstrate the function in a program that sks the user how many times the coin should be tossed and the coin then simulates the tossing of the coin that number of times.
