PLEASE HELP ME The cost, C, to produce b baseball bats per day is modeled by the function C
b. = 0.06b2 – 7.2b + 390. What number of bats should be produced to keep costs at a minimum?

Respuesta :

naǫ
The minimum cost is the y-coordinate of the vertex of the parabola represented by the equation. The x-coordinate is the number of bats.

[tex]C(b)=0.06b^2-7.2b+390 \\ a=0.06 \\ b=-7.2 \\ \\ \hbox{the x-coordinate of the vertex: } \frac{-b}{2a}=\frac{-(-7.2)}{2 \times 0.06}=\frac{7.2}{0.12}=60 [/tex]

60 bats should be produced every day to keep costs at a minimum.

Answer:

60 bats... Just took the quiz
