Parallel bases.

The legs are congruent by definition.

The lower base angles are congruent.

The upper base angles are congruent.

Any lower base angle is supplementary to any upper base angle.

The diagonals are congruent.

200

Step-by-step explanation:

Given that C(x) = 0.1 $x^{2}$ - 40x +9569,

complete the square, then C(x) = 0.1* ( $x^{2}$ - 400x) +9569

= 0.1 * ( $x^{2}$ - 400x + $(400/2)^{2}$ ) +9569 - $(400/2)^{2}$

= 0.1 * (x - 200)^2 - 30431

so the answer is 200 machines
