An air conditioning unit is being designed to provide 36,000 BTU/h (3 tons) of cooling capacity. The air conditioner will operate on a standard throttle expansion refrigeration cycle. Freon 22 will be used as the refrigerant. The evaporator will operate at a temperature of 50°F and the condenser will operate at 140°F. Determine the refrigerant flow rate, compressor power, and the thermal load on the condenser. Assume reversible compression and then consider a compression efficiency of 70%.

Let's remind ourselves of what "linear" means. A linear function can be expressed in the form: y=mx+b. Linear functions do not always have to be in this form, but it is the most common representation. Let's remind ourselves of what the "pieces" in this expression y = mx + b mean. m is ____ You may have learned this as rise/run Remember that rise is a change in Y-values and run is a change in X-values b is the ____-intercept Graphically, this is ____ and this occurs when x = ____ It may also be helpful to remember that the ____-intercept graphically is ____ and this occurs when y = ____

2. Let $Q_1$ be the mean of $x$, $Q_2$ the sample standard deviation of $x$, $Q_3$ the mean of $y$, $Q_4$ the sample standard deviation of $y$, and $Q_5$ the linear correlation coefficient of $x$ and y, where the sequences $x$ and $y$ are as follows: x: -25, -91, 62, 29, 38, 56, 75, 69, -86, 36, -80, -9, y: 85, -19, 46, 21, 73, 10, -19, 54, -27, 24, -8, 47. Let $Q = \ln(3 + |Q_1| + 2|Q_2| + 3|Q_3| + 4|Q_4| + 5|Q_5|)$. Then $T = 5 \sin^2(100Q)$ satisfies:- (A) $0 \le T < 1$. (B) $1 \le T < 2$. (C) $2 \le T < 3$. (D) $3 < T < 4$. (E) $4 \le T \le 5$.

Chapter 8 ECRI Corporation is a holding company with four main subsidiaries. The percentage of its capital invested in each of the subsidiaries (and their respective betas) are as follows: Subsidiary Percentage of Capital Beta Electric utility 60% 0.70 Cable company 25 0.90 Real estate development 10 1.30 International/special projects 5 1.50 1. What is the holding company's beta? 2. If the risk-free rate is 4% and the market risk premium is 5%, what is the holding company's required rate of return? 3. ECRI is considering a change in its strategic focus; it will reduce its reliance on the electric utility subsidiary, so the percentage of its capital in this subsidiary will be reduced to 50%. At the same time, it will increase its reliance on the international/special projects division, so the percentage of its capital in that subsidiary will rise to 20%. What will the company's required rate of return be after these changes?

Consider the differential equation for y (-2x - y)dx + xdy = 0. \frac{\partial M}{\partial y} - \frac{\partial N}{\partial x} = 2. Find an integrating factor. Your answer should be a single variable function. \mu(\text{ }) = 3. Reduce the equation to an exact equation. The resulting exact equation is \text{ }dx + \text{ }dy = 0. 4. Find a simplest function \(F\) so that \(\frac{\partial F}{\partial x}dx + \frac{\partial F}{\partial y}dy = 0\) is the same as the exact equation you obtained in part 3. Don't involve unknown constants in your function \(F\). F = 4. Find the general solution of the exact equation EXPLICITLY. Use the letter c for the constant. y =
