Chapter 1 SOLUTIONS FOR EXERCISES AND PROBLEMS 1.47 Audit‚ Attestation‚ and Assurance Services Students may encounter some difficulty with this matching question because the Special Committee on Assurance Services (SCAS) listed many things that heretofore have been considered “attestation services” (long before assurance services were invented). As a result‚ we believe that this question is a good vehicle for discussing the considerable overlap between attestation and assurance services.

Turbines: A Wind-Wind Solution The majority of energy comes from nonrenewable fossil fuels such as coal‚ natural gas‚ and oil. Americans depend on this energy in almost every way imaginable; from cooking to cleaning‚ from working to traveling‚ to heating and cooling. Wind is a byproduct of solar energy; the uneven heating of the air over land and water creates wind as warm air rises and cool air rushes in to take its place (Bezdek‚ 29 Oct. 2013). Although some people tend to dislike the idea

water and‚ more recently‚ generation of electricity. Contemporary electricity-generating versions are referred to as wind turbines. In the context of our country‚ where we continually suffer from load shedding‚ windmill sounds like a creative solution. Although the idea of setting up windmills here is a new idea‚ the concept is lot older. We have the “Kaptai Dam” in “Karnafuli” where we use the force of water to produce electricity which is based on the same principle.

Applied Mathematics 1 Trigonometric Ratios with solutions O A O cos θ = tan θ = H H A where O = opposite‚ A = adjacent and H = hypotenuse. sin θ = 1. The angle of elevation of the top of a tree from a point on the ground 10m from the base of the tree is 28◦ . What is the height of the tree? Solution We need to find the height of tree which is opposite an angle of 28◦ .Thus O tan θ = A O = A tan θ height of tree = 10 × tan 28◦ =⇒ height of tree = 5.3m 1d.p. 2. Using a surveying

Title: pH and buffer solutions Aim This experiment was carried out to determine the role of buffer solution and the factor which affect the buffer capacity. Besides‚ this experiment was carried out to investigate the solubility of protein casein over a range of pH concentration. This experiment also was carried out to determine the isoelectric point of the casein and the effect of the isoelectric point toward the casein solution.

Meaning of Slack Variables. Slack variables have an important physical interpretation and represent a valuable commodity‚ such as unused labor‚ machine time‚ money‚ space‚ and so forth. Teaching Suggestion 9.2: Initial Solutions to LP Problems. Explain that all initial solutions begin with X1 ϭ 0‚ X2 ϭ 0 (that is‚ the real variables set to zero)‚ and the slacks are the variables with nonzero values. Variables with values of zero are called nonbasic and those with nonzero values are said to be
