Answer: 
Step-by-step explanation:
Given
The unit cost is given by
find the derivative of the unit cost and equate it to zero to obtain the minimum value
Substitute 140 for 
in the cost function, we get
![C(140)=0.6[140]^2-168(140)+30,389\\C(140)=11,760-23,520+30,389\\C(140)=\$18,629](https://tex.z-dn.net/?f=C%28140%29%3D0.6%5B140%5D%5E2-168%28140%29%2B30%2C389%5C%5CC%28140%29%3D11%2C760-23%2C520%2B30%2C389%5C%5CC%28140%29%3D%5C%2418%2C629)
Answer:
tan D = 
or 0.545
tan F = 
or 1.833
Step-by-step explanation:
To find tangent is always 
so the opposite of angle D is line EF which is 4.8 and the adjacent side is line ED which is 8.8 so 
which is or 0.545
The opposite of angle f is line ED which is 8.8 and the adjacent is line EF which is 4.8 so 
is or 1.833
Answer:
Decimal point
Definition:
A <em>decimal point</em> is the symbol that is used to make the separation between the whole part and the fractional part of a number. Currently, not only is a point used to separate both parts, but the comma can also be used.
Example:
The number 39.847, in which 39 is the whole number, while 847 is the decimal part where 8 represent tenths, 4 hundredsths, and 7 thousandths.
Answer:
8.921513269...g/cm
Step-by-step explanation:
the density has this formula: D= m/V
so to solve the V, which refers to volume, you do: 8.4×5.5×4.6= 212.52, and the m, which refers to mass, you already have it. So the last thing to do is:
D= 1896g/212.52= 8.921513269...g/cm
I hope I've been helpful... good luck...!!!
