The weekly demand for dvds manufactured by a certain media corporation is given by
p = −0.0006x2 + 65
where p denotes the unit price in dollars and x denotes the quantity demanded. the weekly total cost function associated with producing these discs is given by
c(x) = −0.002x2 + 13x + 4000
where c(x) denotes the total cost (in dollars) incurred in pressing x discs. find the production level that will yield a maximum profit for the manufacturer. hint: use the quadratic formula. (round your answer to the nearest integer.)

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function. a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
