1. Prepare a budgeted income statement for 20Y9. 2. Prepare a budgeted balance sheet as of December 31, 20Y9, with supporting calculations.Answer 1 and 2 PR 22-4A Cash budget Obj.5 The controller of Bridgeport Housewares Inc. instructs you to prepare a monthly cash budget for the next three months.You are presented with the following budget information September October November $250,000 $300,000 $315,000 150,000 180,000 185,000 42,000 48,000 51,000 200,000 Sales Manufacturing costs. Selling and administrative expenses Capital expenditures The company expects to sell about 10% of its merchandise for cash. Of sales on account, 70% are expected to be collected in the month following the sale and the remainder the following month (second month following sale.Depreciation, insurance, and property tax expense rep resent $50,000 of the estimated monthly manufacturing costs. The annual insurance premium is paid in January, and the annual property taxes are paid in December. Of the remainder of the manufacturing costs, 8o% are expected to be paid in the month in which they are incurred and the balance in the following month. Current assets as of September 1 include cash of $40,000,marketable securities of $75,000,and accounts receivable of $300,000 ($60,000 from July sales and $240,000 from August sales).Sales on account for July and August were $200,000 and $240,000,respectively.Current liabilities as of September 1 include $40,000 of accounts payable incurred in August for manufacturing costs.All selling and administrative expenses are paid in cash in the period they are incurred.An estimated of S25,000 is expected to be declared in October and paid in November.Management desires to maintain a minimum cash balance of $50,000. Instructions 1. Prepare a monthly cash budget and supporting schedules for September,October, and November 2. On the basis of the cash budget prepared in part 1, what recommendation should be made to the controller?

Q3. In a 230 kV system, using the following circuit in Fig-Q3 for analysis of resistance switching to [7.5] reduce the re-striking voltage, R.R.R.V and severity of the transient oscillations, a resistance of 500 ohm is connected across the contacts of the circuit breaker. In the said system, the reactance and capacitance up to the location of the circuit breaker is X ohm and 0.02 µF, respectively. Determine the following: (i) natural frequency of oscillation (ii) damped frequency of oscillation (iii) critical value of resistance. (iv) the value of resistance which will give damped frequency of oscillation, one-fourth of the natural frequency of oscillation. Assume, X will be the average value of last two digits of your student ID. $V = V_m \cos \omega t$ $L$ 00000 $i$ $V_c$ $C$ $i_c$ $R$ $i_R$ Fig-Q3 : Circuit for analysis of Resistance Switching Fault

Definition 2. Suppose that an object is displaced by a vector of $\vec{d}$ while under the influence of force $\vec{F}$. Then the work done by $\vec{F}$ is the value $W = \vec{F} \cdot \vec{d}$. The units on W are the units on $||\vec{F}||$ times the units on $||\vec{d}||$. 1. A box is sliding down a frictionless hill with a grading of 0.5. Suppose that the force due to gravity has a magnitude of 600 N. a) Draw a force diagram and the displacement vector in a single picture. b) Find the work done by gravity after the box slides 10 feet.

Problem 2 A communication system uses the signals $s_1(t)$, $s_2(t) = 3s_1(t)$, and $s_3(t) = 0$, to transmit one of the three messages $m_1$, $m_2$, and $m_3$. Assume that the energy of the signal $s_1(t)$ is given as $E_1 = A^2T$. The channel is an additive white Gaussian noise channel with noise power spectral density equal to $N_0/2$. A. Suggest and plot the signal constellation that represent the signal set. B. If the three messages are equiprobable, what are the optimal decision rules for this system? Show the optimal decision regions on the signal constellation you plotted in part A. C. If the signals are equiprobable, express the error probability of the optimal detector in terms of the average SNR per bit. D. Assuming this system transmits 4000 symbols per second, what is the resulting transmission rate (in bits per second)? This Problem is worth 15 Points.
