When the price of a certain commodity is p dollars per unit, the manufacturer is willing to supply x thousand units, where π₯ 2 β 2π₯βπ β π 3 = 31 How fast is the supply changing the price when the price is $ 9 per unit and increasing at the rate of 20 cents per weekΒ
Suppose the output at a certain factory is π = 2π₯ 3 + π₯ 2π¦ + π¦ 2 units, where π₯ is the number of hours of skilled labour used and π¦ is the number of hours of unskilled labour. The current labour force consists of 30 hours of skilled labour and 20 hours of unskilled labour. Use calculus to estimate the change in unskilled labour y that should be made to offset a 1-hour increase in skilled labour x so that output will be maintained at its current level
Find ππ¦ ππ₯ if π₯ 2π¦ + 2π¦ 3 = 3π₯ + 2π¦
An environmental study of a certain suburban community suggests that its average daily level of carbon monoxide will be πΆ(π) = β0.5π 2 + 17 Parts per million when the population is p thousand. It is estimated that t years from now, the population of the community will be π(π‘) = 3.1 + 0.1π‘ 2 thousand. At what rate will the carbon monoxide level be changing with respect to time 3 years from now?
