Allison:
A company's daily costs in dollars in producing x items is given by C(x)=0.001x^2-6x+20,000 with C in dollars. Find the production level that will minimize cost. What is the minimum cost? Find Vertex.
Allison:
Do I use the equation -b/2(a)?
Allison:
@Vocaloid @Hero @Dude
jhonyy9:
- i think may be the minim level of this quadratic @dude ?
dude:
Yeah that tells us the minimum (x value)
jhonyy9:
thank you very much
jhonyy9:
@Allison hope this will help you
Allison:
HUH?
Allison:
So if I re-write it, it's y=0.001x^2-6x+20,000
jhonyy9:
yes and you need just to calcule the minime level of this quadratic - hope you know the way !!!
Allison:
Uh it's too big to see on my calculator
dude:
Yeah they gave you a simple equation Vertex does give you minimum value. You’re right, use -b/2a
Allison:
But b is already negative, do I keep it negative?
dude:
No that changes to positive
Allison:
So 6/0.001*2
dude:
Yes
Allison:
12,000
Allison:
Plug that in for x right
dude:
Not 12,000 D:
Allison:
Boi
Allison:
0.003
dude:
Boi recheck with your calculator 6/2*.001
Allison:
.003
Allison:
?!?!?!?!
dude:
Breh it’s supposed to be in the thousands 6/.002 => 3,000
Allison:
Oop-
dude:
Put that into x to find y
Allison:
11,000
dude:
Yes
Allison:
