The cost, in dollars, of producing x belts is given by Upper C (x )equals 594 plus 10 x minus 0.067 x squared. Find the rate at which average cost is changing when 576 belts have been produced. When 576 belts have been produced, the average cost is changing at nothing dollars per belt belts per dollar for each additional belt.

When 576 belts have been produced, the average cost is changing at 0.0652(decreasing) dollar per belt

Step-by-step explanation:

If x is the number of units of a product produced in some time interval then average cost function is given as,  

Cost function is given as,  

Substituting the value in formula for average cost function,  

Simplifying,

To find the rate of average cost that is, . So differentiating function with respect to x,  

Applying sum rule and difference rule of derivative,

Applying constant multiple rule of derivative,  

Since,  

Applying power rule and constant rule of derivative,

Substituting the value of ,

Negative sign indicates that rate of average cost is decreasing.

Therefore, the average cost is changing at the rate of 0.0652(decreasing) dollar per belt

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
