1 answer:
vazorg [7]3 years ago
6 0

Answer:

Step-by-step explanation:

a = - 4

b = 10

c = - 8

The discriminate is

D = b^2 - 4ac

D = 10^2 - 4*(-4)(-8)

D = 100 -  128

D = - 28 which is not a nice number

Because the Discriminate has a minus result, there are no real zeros.

Andreas93 [3]

Answer:

  • Minimum 100 bicycles
  • Minimum cost is 13500

Step-by-step explanation:

<u>Given function:</u>

  • C(x) = 3x^2- 600x + 43500

Minimum cost is obtained at vertex.

Vertex is determined by formula x = -b/2a, in standard form of

f(x) = ax^2 + bx + c

<u>Vertex of the given function is:</u>

  • x = -(-600)/(2*3) = 100

b.

<u>Cost at vertex is:</u>

  • C(100) = 3*100^2 - 600*100 + 43500 = 13500
