kennedymarihllisgu68742Lv1in Electrical Engineering·6 Jan 2023United States tax law Assume that Marietta's maximum $179 expense after applying the phase-out limitation is $270,000.Also assume that Marietta elects to claim the entire $270,000 expense and it chooses to apply it against the machinery. Further assume that Marietta elects out of bonus depreciation and reports $410,000 of taxable income before deducting any $179 expense and depreciation What amount oftotal depreciation (including $179 expense) is Marietta able to deduct on the machinery for the year?
2006hassanallyLv1in Electrical Engineering·5 Jan 2023Engineer, During the transmission of electricity over long distances, an alternating current is passed over aluminium cables at high voltages and low current. .i) Give two reasons why is alternating current (a.c) used in preference to direct current (d.c) ?. ii) Give two reasons why are aluminium cables preferred to copper for long distance transmission of electricity?
kennedymarihllisgu68742Lv1in Electrical Engineering·5 Jan 20232. LMIs are inequalities of the form where is known and is a variable for i = 0 ... n. However, in controls LMIs are most naturally formulated as and , where are known, is symmetric, and s an unknown matrix. Show that any expression of the form 4 can be written in the form 3 (or show the opposite).
