Answer:
83,491.67 dollars
Step-by-step explanation:
Given that a certain electronics manufacturer ound that the average cost C C to produce x DVD/Blu- ray players can be found using the equation 
To find the minimum average cost per machine we can use derivative test.
we find first and second derivative.
If for a particular value of x first derivative is 0 and second derivative is positive, then that x satisfies the minimum cost criteria.

Second derivative is always positive
I derivative =0 gives

For 83 players the cost would be minimum
Minimum cost = 
Answer:
I think the answer is 7.75/100
Answer:
Not sure but 2 would be the same as 1 so 39.5 and 3 and 4 would be 50.5
Step-by-step explanation:
1 and 3 make a right angle and so does 4 and 2 so all I did was subtract 39.5 from 90 since a right angle=90 degrees
Answer:
if you use perimeter area you can get answer
