A Top Trading Ltda. decidiu adquirir um financiamento no valor de R$ 1.200.000,00 para o desenvolvimento de um novo produto. Após alguns estudos, os analistas da empresa optaram por obter os recursos via empréstimo bancário dividido igualmente em duas instituições financeiras. As taxas apresentadas pelas instituições foram de 10% e 8%. Se o imposto de renda pago pela empresa é de 34%, o custo de capital do financiamento deve ser de:

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.
