Answer:
No units
Step-by-step explanation:
The cost function is given by;

To find the units manufactured at a cost of $5,560
We equate the C(x) to 5560 and solve for x.



The discriminant of this equation is negative.
That is,

Hence the equation has no real roots.
This means no units can be produced at $5,560
Answer:
x = 1.8
Step-by-step explanation:
10.4 - 5 = 5.4 (subtract 5 from each side)
to isolate the variable, x, divide each side by 3
5.4/3 = 1.8
<span>The ratio of 2 similar areas is the square of the ratio of their RADIUS or (sides)
R²=(2/3)² = 4/9 This should be the answer
Whereas R³ = (2/3)³ = 8/27 is the ratio of their volume & not area
