Answer:
see explanation
Step-by-step explanation:
1
(x + 5)² = 4 ( take the square root of both sides )
x + 5 = ± = ± 2 ( subtract 5 from both sides )
x = - 5 ± 2, thus
x = - 5 - 2 = - 7
x = - 5 + 2 = - 3
--------------------------------------------
2
(x + 6)² = 7 ( take the square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ± , thus
x = - 6 -
x = - 6 +
------------------------------------------------
3
(x - 2)² = 18 ( take the square root of both sides )
x - 2 = ± = ± = ± 3 ( add 2 to both sides )
x = 2 ± 3, thus
x = 2 - 3
x = 2 + 3

Answer:
$562,500 per hour
Step-by-step explanation:
The cost will be a minimum where C'(x) = 0.
C'(x) = 0.56x -0.7 = 0
x = 0.7/0.56 = 1.25
The cost at that production point is ...
C(1.25) = (0.28×1.25 -0.7)1.25 +1 = -0.35×1.25 +1 = 0.5625
The minimum production cost is $562,500 per hour for production of 1250 items per hour.
_____
<em>Additional comment</em>
This is different than the minimum cost <em>per item</em>. This level of production gives a per-item cost of $450. The minimum cost per item is $358.30 at a production level of 1890 per hour.
