Your car wash company is advertising on local radio, on local television, and via direct mail. You believe that a radio campaign raises your gross profit by $250, a television campaign raises it by $360, and a direct mail campaign raises it by $100. The cost of a radio campaign is $125, the cost of a television campaign is $60, and the cost of a direct mail campaign is $100. If you cannot change your total advertising budget, should you reallocate your spending? If yes, explain how. If no, explain why not A. Your current spending is not optimal because your marginal benefit from each type of advertising is not equal to the marginal cost. You definitely should increase spending on radio campaigns and reduce it on direct mail campaigns. B. Your current spending is not optimal because your marginal benefit from each type of advertising is not equal to the marginal cost. You definitely should increase spending on radio campaigns and reduce it on TV campaigns C. Your current spending is not optimal because your marginal benefit from each type of advertising is not equal to the marginal cost. You definitely should increase spending on TV campaigns and reduce it on direct mail campaigns. D. Your current spending is optimal because your marginal benefit from each type of advertising is equal to the marginal cost. You should not reallocate your spending on advertisements

Question 16 (6.25 Points) The following single-piston-cylinder engine has a connecting rod 80 mm long and a mass of 0.100 kg, with the mass center 10 mm from the crankpin end A. The mass of the piston is 0.180kg. At the instant shown and for the given data, determine the magnitude of the total force of the piston against the cylinder wall. At the instant shown $\phi = 13.7609^\circ$ $\frac{d^2x}{dt^2} = -787 \frac{m}{s^2}$ $P = 4274N$ Magnitude of the acceleration of the piston Magnitude of the gas force A 1060 N B 1050 N C 1030 N D 1020 N E 1010 N

Atomic weights: C=12.011 g/mole, H=1.0079 g/mole, O=15.9994 g/mole For MS (m/z) C=12; H=1; O=16; N=14 (Show your work. That's the only way I can assign partial credit.) (4 pt.) Indicate which C-C bond would most likely fragment in a mass spectrometer for the following molecule. (Choose a bond that will produce an ion smaller than the molecular ion.) (6 pt.) a. Draw the structure of the fragments with (m/z) = 105 and 57 that could be seen in the mass spectrum of the following ketone. b. (2 pt.) Is the McLafferty rearrangement possible for this molecule? (4 pt.) Calculate the (m/z) for the molecular ion of Nevirapine, which is a medication used to treat or prevent HIV.
