We are running programs where values of type int are 32 bits. They are represented in two's complement, and they are right-shifted arithmetically. Values of type unsigned are also 32 bits. We generate arbitrary values x and y, and convert them to unsigned values as follows:/* Create some arbitrary values /int x = random();int y = random();/* Convert to unsigned */unsigned ux = (unsigned) x;unsigned uy = (unsigned) y;For each of the following C expressions, you are to indicate whether or not the expression always yields 1. If it always yields 1, describe the underlying mathematical principles. Otherwise, give an example of arguments 'that make it yield 0. A. (x-y)B. ((x+y) > 2)

A plane wall of thickness 2L = 60 mm and thermal conductivity k= 5W/m. K experiences uniform volumetric heat generation at a rate qdot , while convection heat transfer occurs at both of its surfaces (x=-L, +L), each of which is exposed to a fluid of temperature T[infinity] = 30 oC. Under steady-state conditions, the temperature distribution in the wall is of the form T(x) = a + bx+ cx2 where a = 860C, b=-2000C /m, c=-2 104 0C /m2, and x is in meters. The origin of the x-coordinate is at the midplane of the wall. a) Sketch the temperature distribution and identify significant physical features. b) What is the volumetric rate of heat generation in the wall? c) Determine the surface heat fluxes at x=-L, +L, and How are these fluxes related to the heat generation rate? d) What are the convection coefficients for the surfaces at x=-L and x=+L?

You decided that price will be the determining factor in choosing a new ERP system. You select the option with the lowest price. The executive team likes the price tag, but soon you realize that the cost was so low because every phase of the project requires additional charges for customer support As your team begins working on the migration to the new module, you discover a compatibility problem between the new POS system and the old inventory management system that you were planning on replacing later. After a great deal of research and with limited support from your new vendor, you realize you have two options: replace the inventory management system at the same time, or invest some money into adapting the old system so it will work until you can replace it later
