This problem involves three chemicals a, b, c. you have a liters of chemical a, b liters of chemical b, and c liters of chemical c (for each chemical you have a pure solution). there are n potential customers. the i-th customer wants di liters of an ai : bi : ci mixture of chemicals a, b, c and is willing to pay pi dollars per liter of the desired mixture. you need cash. you want to get as much money as possible by creating mixtures and selling them to the potential customers. the customers will purchase your mixture even if you only partially satisfy their demand (for example, if a customer wants 3 liters of a 7 : 8 : 9 mixture and is willing to pay $8 per liter and you supply 1.2 liters of a 7 : 8 : 9 mixture they will pay you $9.6). give a linear program for the problem. clearly describe the variables in your linear program.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
