The resale value os a certain idustrial machine decreases over a 10 year period at a rate that changes with time, when the machine is x years old, its value is decreasing at a rate of 220(x-10) dollars/year. By how much does the machine depreciate during the second year? Please see attached for full question.
Test for convergence or divergence, absolute or conditional. If the series converges and it is possible to find a sum, then do so (see attachment for equations, please - thanks!)
