Suppose it has been determined that the sales at a gallery decline after the end of an advertising campaign, with daily sales given by S- 8000(2-0.1x) where S is in dollars and x is the number of days after the campaign ends. What are the daily sales 10 days after the end of the campaign?

The intensity of sound I (as a multiple of the average minimum threshold of hearing intensity) is related to the decibel level D (or loudness of sound) according to I = 10D/10 (a) Express 10D/10 using radical notation. 10D/10 (b) The background noise level of a relatively quiet room has a decibel reading of 34. Find the intensity I, of this noise level. (Round your answer to two decimal places.) I (c) A decibel reading of 138 is at the threshold of pain. If I, is the intensity of this threshold and I, is the intensity found in part (b), express the ratio I,/I, as a power of 10. I2 = 10 Approximate the ratio. (Round your answer to two decimal places.) x 1010
