The surface area S of a ring in shape of a torus with an inner radius r and a diameter d is given by: S = n²(2r + d)d The ring is to be plated with a thin layer of coating. The weight of the coating W can be calculated approxi- mately as W = ySt , where y is the specific weight of the coating material and t is its thickness. Write an anonymous function that calculates the weight of the coating. The function should have four input arguments, r, d, t, and y. Use the anonymous function to calculate the weight of a gold coating (y = 0.696 lb/in.³) of a ring with r = 0.35 in., d = 0.12 in., and1 = 0.002 in.

Given the code: void e(int x, int y) { if(y<2) { cout << x << " "; return; } cout << x << " "; e(x+1, y-1); } 1. Trace the function when x and y are 4.

In Kotlin, write a higher-order function with an expression body that takes an int n and a function f from int to int and returns the result of calling f(f(n)). For example if you call the function with n = -5 anda  function that calculates absolute value, your function will return 5, and if you send the value 2 and a function that calculates the sqaure of an int, the function will return 16. in addition to the function, write the syntax to call it with:a. a function name as the function arguementb. some lambda expression as the function argument

A store has two different coupons that customers can use. One coupon gives the customer $30 off their purchase, and the other coupon gives the customer 40% off of their purchase. Suppose they let a customer use both coupons and choose which coupon gets applied first. For this context, ignore sales tax. Let f be the function that inputs a cost (in dollars) and outputs the cost after applying the "$30 off" coupon, and let g be the function that inputs a cost (in dollars) and outputs the cost after applying the "40% off" coupon. Which of the following correctly represents the fact that the cost of purchasing $190 worth of goods is $84 when the "40% off" coupon is applied first followed by the "$30 off" coupon? g(f(84))=190 f(g(190))=84 g(f(190))=84 f(g(84))=190 f(f−1(190))=84

Write a fraction calculator program that adds, subtracts, multiplies, and di-vides fractions. Your program should check for the division by 0, have and use the following functions:(a) subtract - finds the reduced difference of a pair of given fractions, by makingthe second fraction negative then using the add function.(b) multiply - finds the reduced product of a pair of given fractions.(c) divide - finds the reduced quotient of a pair of given fractions by inverting the second fraction then using the multiply function

I can't seem to do the nested IF function in column T3.

A store has issued two different coupons for its customers to use. One coupon gives customers $25 off their purchase price, and the other coupon gives customers 30% off of their purchase. The store allows customers to use both coupons and choose which coupon to apply first. For this context, ignore sales tax. Let D be the function that inputs a cost (in dollars) and outputs the cost after applying the "$25 off" coupon, and let P be the function that inputs a cost (in dollars) and outputs the cost after applying the "30% off" coupon.     1.A customer purchases an item for $140 and asks the cashier to apply the "$25 off" coupon first, followed by the "30% off" coupon. Use function notation to represent the cost of the item (in dollars) after the two coupons are applied. 2.A customer purchases an item for $140 and asks the cashier to apply the "30% off" coupon first, followed by the "$25 off" coupon. Use function notation to represent the cost of the item (in dollars) after the two…

Write a function sumOddInts(). sumOddInts should return the sum of all odd integers between the values provided to the two parameters, inclusive, e.g., sumOddInts(5,9) should return 21. start and finish do not have to be odd, e.g, sumOddInts (4,8) should return 12. start and finish do not have to be positive, e.g., sumoddlnts(-5,7) should return 7, However, finish may be assumed to be greater or equal to start. whereas Python has a modulo operator "%", MATLAB has a built-in mod() function that returns the remainder. For instance, >> mod (13,5) ans = 3 >> mod (13,2) ans = 1 Notes: End all assignment statements with a semi-colon to suppress output to screen. Include the key word end at the end of your function.

Exercise 5   The greatest common divisor (GCD) of a and b is the largest number that divides both of them with no remainder. One way to find the GCD of two numbers is based on the observation that if r is the remainder when a is divided by b, then gcd(a, b) = gcd(b, r). As a base case, we can use gcd(a, 0) = a. Write a function called gcd that takes parameters a and b and returns their greatest common divisor.
