Answer B
Step-by-step explanation:
Your answer should be written in paragraph/essay format.
Any sources used should be cited at the bottom of your paper.
All answers should show you have learned something from Unit 9. Material from other units will not be graded for this assignment.
If you are stuck, you can think about the following topics: textile mills, interchangeable parts, the Lowell System, unions, labor reform, steamboats, railroads, coal, the telegraph, and/or new inventions.
Answer: x - 8
Step-by-step explanation:
Factor it and you'll be fine.
Answer:
260 machines for minimum cost.
Step-by-step explanation:
c(x) = 0.3x^2 - 156x + 26.657
Finding the derivative:
c'(x) = 0.6x - 156
0.6x - 156 = 0 for maxm/minm cost.
x = 156 / 0.6
= 260
The second derivative is positive (0.6) so this is a minimum.
Answer:
m = -4
Step-by-step explanation:
First you have to deal with the right side of the equation since it's not spread out.
You therefore have to distribute (in order)
5×1= 5,
5×-m= -5m
And
-2×1 = -2
-2×-m = 2m
Now set it up in the order it was at first (not necessary, but helpful)
15 = 5-5m-2+2m
Add the common values...
5-2= 3
-5m+2m= -3m
Your equation should now look like this:
15= 3-3m
At this point you need to get the common values on the same side, so you would subtract 3 from both sides
15-3= 12
3-3= 0
Since you the 3 cancelled out on the right side, your equation now looks like this:
12= -3m
(Or -3m= 12)
At this point you only need to get m by itself so you would divide by -3 on both sides
-3m/-3= m (or 1m: m is understood as such)
12/-3= -4
The final answer should be
m = -4
Same I can't see it either
