Mathematics: Which is the most accurate way to estimate 52% of 63

200Step-by-step explanation:Given that C(x) = 0.1 - 40x +9569,complete the square, then C(x) = 0.1* ( - 400x) +9569 = 0.1 * ( - 400x + ) +9569 - = 0.1 * (x - 200)^2 - 30431so the answer is 200 machines...

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
