What was ‘long wall mining’ and what influence did it have on the development of socio-technical systems theory? critically discuss how this theory developed so many years ago can still be applied to warehouse design and improvement today.

You invest all the money you earned during your summer sales job (a total of $45,000) into the stock of a company that produces fat and carb-free cheetos. the company stock is expected to earn a 14% annual return; however, 5 years later it is only worth $20,000. turns out there wasn't as much demand for fat and carb-free cheetos as you had hoped. what is the annual rate of return on your investment?

Suppose a firm faces a fixed price of output, 푝푝= 1200. the firm hires workers from a union at a daily wage, 푤푤, to produce output according to the production function 푞푞= 2퐸퐸12. there are 225 workers in the union. any union worker who does not work for this firm is guaranteed to find nonunion employment at a wage of $96 per day. a.what is the firm’s labor demand function? b.if the firm is allowed to choose 푤푤, but then the union decides how many workers to provide (up to 225) at that wage, what wage will the firm set? how many workers will the union provide? what is the firm’s output and profit? what is the total income of the 225 union workers? c.now suppose that the union sets the wage, but the firm decides how many workers to hire at that wage (up to 225). what wage will the union set to maximize the total income of all 225 workers? how many workers will the firm hire? what is the firm’s output and profit? what is the total income of the 225 union workers? [hint: to maximize total income of union, take the first order condition with respect to w and set equal to 0.]

Which of these is not a result of regular exercise
