Answer:
100 bicycles
Step-by-step explanation:
If C(x)= 0.2x²-0.4x+6.636
The general form of a quadratic expression is given as: ax²+bx+c
Therefore from C(x),
a=0.2, b=-0.4, c=6.636.
C(x) is a parabola with its "a" coefficient 0.2 being positive so the curve opens upward indicating that the vertex is a minimum.
We simply need to find the vertex of:
C(x)= 0.2x²-0.4x+6.636
This occurs when:
x = -b/(2a)
x = -(-0.4)/(2*0.2)
x = (0.4)/(0.4)
x = 1
Since x=1 at the vertex, the company should build 100 bicycles to minimize the average cost per bicycle.

Answer:
The correct answer is 619.
Step-by-step explanation:
A number is said to have point symmetry when turning it upside down, that is, turning it 180º, remains the same.
As for geometric figures, the same thing happens. It is symmetrically the same if it is built around a center and when turning it does not change its shape.
That is why the correct option is 619 (6I9).
