You have just completed a $21,000 feasibility study for a new coffee shop in some retail space you own. You bought the space two years ago for $96,000, and if you sold it today, you would net $120,000 after taxes. Outfitting the space for a coffee shop would require a capital expenditure of $33,000 plus an initial investment of $4,600 in inventory. What is the correct initial cash flow for your analysis of the coffee shop opportunity? Identify the relevant incremental cash flows below. (Select all the choices that apply) A. Price you paid for the space two years ago. B. Capital expenditure to outfit the space C. Amount you would net after taxes should you sell the space today D. Initial investment in inventory E. Feasibility study for the new coffee shop Calculate the initial cash flow below: (Select from the drop-down menus and round to the nearest dollar.) 1 2 3 4 Free Cash Flow

The transmission tower ABC shown supports forces from three electrical wires at points C, D, and E. The tower is supported at point A by a concrete foundation, and this foundation is normally adequate to support the tower without the guy wire BF. For towers that are sited in poor soil, or when the horizontal forces from the electrical wires are high due to a sharp turn, an optional guy wire BF may also be used to help support the tower. Neglect the weight of the tower. Take the value of P to be 4 kN. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. If guy wire BF is used, determine the force it must support so that the moment reaction at A is zero. (Round the final answers to four decimal places.) (Do not include a minus sign in your response.) The force the guy wire supports is 121.7479 kN The horizontal component of the reaction force at A is 7.9198 kN The vertical component of the reaction force at A is 130.6826 kN

Texts: (a) Planning the network addressing scheme (14 marks) Before cabling and connecting your network devices, you will need to plan your addressing scheme to make sure you have enough addresses available for each device on the network. You must work out your internal network address according to the last numerical digit of your Personal Identifier (PI). For example, if your PI is X1234567, then the digit to use is 7; if your PI is Y876543B, then 3 is the digit to use. Once you have identified the digit to use, you need to replace the third octet in the IPv4 address 192.168.0.0 with your digit, giving you something like 192.168.7.0 or 192.168.3.0, respectively, for the examples above.
