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 = 
The length of the diagonal line is 191 meters.
135² + 135² = c²
18225+18225 =c²
√36450 = √c²
190.91 = c
Round to the nearest meter = 191 meters

Answer:
B, 70pi ft2
Step-by-step explanation:
The equation to find surface area of a cylinder is 2(pi)(r)(h)+2(pi)(r)^2. So now plug the numbers in.. 2(pi)(5)(2)+2(pi)(5)^2 now, simplify. 20pi+50pi= 70pi ft2.
