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:
18.86 feet
Step-by-step explanation:
One rotation of the tire is equal to the circumference of the tire
The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where
π = 22/7
d = diameter
The size of one revolution = 2 x 22/7 = 44/7 feet
The distance covered in one rotation of the tire is 44/7 feet
The distance covered in 3 rotations = (44/7) x 3 = 18.86 feet
