An accessories company finds that the cost, in dollars, of producing x belts is given by Upper C (x )equals 720 plus 35 x minus 0.063 x squared. Find the rate at which average cost is changing when 180 belts have been produced.

The average cost of belt is decreasing at a rate 0.085 dollars per belt  when 180 belts have been produced.

Step-by-step explanation:

We are given the following in the question:

Cost function:

where x is the number of belts.

Average cost =

Rate of change of average function:

Change in average cost when 180 belts have been produced

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
