For each machine-representable number r, define f (r) to be the next larger machine- representable number. Consider the following statements: (a) For fixed-point (integer) arithmetic, the distance between r and f (r) is constant. (b) For floating-point arithmetic, the relative distance | (f(r)-r) /r | is con- stant (for r # 0). Are the statements true or false? Give examples or counterexamples to explain your rea- soning.²

(Translate the following argument into PL using letters to represent simple propositions as needed.) 1. All even numbers are divisible by 2, and all odd numbers aren't. A number n being odd implies that n is not divisible by 2. A number n is odd if an only i it is not divisible by 2. It can't be the the case that a number is both greater than 1 and not a prime number. Therefore, 3 is an odd prime number.

Question: Chocolate Thief Problem I gave some chocolates to students for their extraordinary performances. A chocolate is a cube shaped thing, which has length, width and height. All the students got the same amount of chocolates; their dimensions may be different but the volumes are the same. Now some of the students are claiming that there is one chocolate thief among them. So, it's not an easy task for me to find the chocolate thief, so I am asking your help. You are given the names of the students and the dimensions of their chocolates; you have to find the name of the chocolate thief. You can assume that there can be at most one thief and if there is a thief, he took some portion of the chocolate from exactly another student (not students). Input Input starts with an integer T (≤ 100), denoting the number of test cases. Each case starts with a line…
Do this question: Fill in the blanks so that the argument in part (b) has the same logical form as the argument in part a: a. If n is divisible by 6, then n is divisible by 3. If n is divisible by 3, then the sum of the digits of n is divisible by 3. Therefore, if n is divisible by 6, then the sum of the digits of n is divisible by 3. (b). If this function is ______________ then this function is differentiable. If this function is ______________ then this function is continuous. Therefore, if this function is a polynomial, then this function ______________. a. If all computer programs contain errors, then this program contains an error. This program does not contain an error. Therefore, it is not the case that all computer programs contain errors. b. If ______________, then ______________. Tom is not Python Programmer.

Please Answer this in C++ only Devo is learning Combinatorics in his college. He finds it very interesting to calculate number of ways of going to point (c, d) from point (a, b) in co-ordinate plane. We can take horizontal and vertical steps only and cannot visit at a point twice. In a step, you can move one unit only. We have to reach to the point (c, d) from the point (a, b) using abs(a-c) + abs(b-d) steps only. Devo has two sets of points. Set A contains points having X co-ordinate 0 and Y co- ordinates varying from 1 to N (both inclusive). Set B contains points having X co- ordinate K and Y co-ordinates varying from 1 to N (both inclusive). Both sets contain N number of integral points. He wants to calculate the sum of number of ways to going to each point of set B from each point of set A. As the answer can be large, print it modulo 1000000007. Input 2 22 45 Output 8 236
You are asked to write a simple C program that will accept an integer value in the range of 5-95 and as a multiple of 5 representing the number of cents to give to a customer in their change. The program should calculate how many coins of each denomination and display this to the user. Valid coin values are 50, 20, 10 and 5. Your solution (program and algorithm) should be modular in nature. This requires the submission of a high-level algorithm and suitable decompositions of each step. Note that for this problem the principle of code reuse is particularly important and a significant number of marks are allocated to this. You should attempt to design your solution such that it consists of a relatively small number of functions that are as general in design as possible and you should have one function in particular that can be reused (called repeatedly) in order to solve the majority of the problem. If you find that you have developed a large number of functions which each performs a…
A number of the form a + ib, in which i2 = -1 and a and b are real numbers, is called a complex number. We call the real part and b the imaginary part of a + ib. Complex numbers can also be represented as ordered pairs (a, b). The addition and multiplication of complex numbers are defined by the following rules: (a + ib) + (c + id) = (a + c) + i(b + d ) (a + ib) * (c + id) = (ac - bd) + i(ad + bc) Using the ordered pair notation, these rules are written as: (a, b) + (c, d) = ((a + c), (b + d )) (a, b) * (c, d) = ((ac - bd ), (ad + bc)) C++ has no built-in data type that allows us to manipulate complex numbers. Construct a data type, complex Type, that can be used to process complex numbers. Overload the stream insertion and stream extraction operators for easy input and output. We will also overload the operators + and * to perform addition and multiplication of complex numbers. If x and y are complex numbers, we can evaluate expressions such as x + y and x * y.
In CORAL LANGUAGE please and thank you : Given three floating-point numbers x, y, and z, output x to the power of y, x to the power of (y to the power of z), the absolute value of x, and the square root of (x * y to the power of z). Output all results with five digits after the decimal point, which can be achieved as follows:Put result to output with 5 decimal places Ex: If the input is: 5.0 2.5 1.5 the output is: 55.90170 579.32402 5.00000 6.64787 Hint: Coral has built-in math functions (discussed elsewhere) that may be used.
