4 of 9 Item 1 Willa and Westley are siblings who built a hair salon business from the ground up. They are now contemplating opening an additional salon location. The estimate to open an additional salon would mean adding $1 million in expenses and a revenue of $2 million in total over the next 5 years (all other things equal). Willa and Westley decide Item 2 to take on the new salon because the expected marginal benefit ($2 million over 5 years) is greater than the estimated marginal cost ($1 million). Item 3 Item 4 to open a second salon because the marginal cost of the new salon is low compared to other similar projects. to not open a new salon because the marginal costs proved to be too high. Item 5 Item 6

Constructed Response Question choice 5-2: A staircase is pictured above. It consists of four steps and four risers. The step at the upper left is 1.5 feet long. Each of the three steps is 12 inches long. Each of the four risers is 9 inches high. The staircase is 2 yards wide. Using your measure conversions and geometry: a) Find how many square feet of carpeting would be necessary to cover the steps and risers. Then find out how many square inches this would be as well as how many square yards this would be, and; b) Find how many cubic feet of concrete would be required in order to build this staircase.

4. Suppose we have a continuous, differentiable function \(f\) with the following properties: \(\lim_{x \to \infty} f(x) = -2\) \(\lim_{x \to -\infty} f(x) = -2\) \(f'(3) = 0\) \(f''(x) < 0\) on the interval \((1, 5)\). \(f''(x) > 0\) on the intervals \((-\infty, 1)\) and \((5, \infty)\). (a) (4 points) Sketch a possible graph of \(f\). (b) (2 points) From our given information, does \(f\) definitely have an absolute maximum? If so, where does it occur?

1) Consider the magnetic structure shown below. a. Draw the analogous magnetic circuit, clearly showing the MMF, the flux and the various reluctances. b. Determine the current "i" required to establish a flux of 2.4(10)-4Wb in the magnetic circuit. Consider that the fringing effect increases the area of the air-gap by 10%. c. Would a 100% increase in the magnetic permeability, result in a corresponding decrease in the current required to establish the same flux as before? Justify your answer. Metal Core Depth = 0.01 m, ?r = 1000 i Amp N = 500 turns (as shown) 0.06 m 0.02 m 0.04 m 0.04 m 0.002 m Air-gap Drawing not exactly to scale
