To answer this item, we take the differential of the equation and equate to zero.
C(x) = 0.8x² - 256x + 25939
Differentiation,
dC(x) = 1.6x - 256
dC(x) = 1.6x - 256 = 0
The value of x from the derived equation above is 160.
Thus, the number of machine to be made in order to minimize the cost should be 160.
Answer:
12/40 (simplified = 3/10)
Step-by-step explanation:
2 x 6 = 12
5 x 8 = 40
Answer:
a
Step-by-step explanation:
just read through the answer choices and you can see that the other three are wrong
There are 3 shorter boards because if you divide 27 by 9 it equals 3.
sqrt (-1) = i the imaginary number
so the negative sqrt (-1) = -i
