Question

calculus

The profit generated from producing and selling x floopers is given by P(x) = -0.01 x**2 + 50 x - 8000 dollars.

Find the marginal profit when 4000 floopers are being produced

Answer 1

marginal profit is given by P'(x)
what do you have for the derivative of P(x) ?

Answer 2

that's all they gave me

Answer 3

I'm not asking you to give me more info, I'm asking you to take the derivative of P(x) to find the marginal profit function P'(x)

Answer 4

oh ok

Answer 5

does that mean you don't know how to take the derivative of P(x) ?

Answer 6

I know how I was just moving to a different problem since you left the question

Answer 7

but im finding the deriv now

Answer 8

I get an update when you respond, don't worry about what question I'm viewing. I'll be here to check your progress.

Answer 9

f'(x) = -0.0001x+50

Answer 10

the first term is wrong
-0.01x^2
derivative is
-0.01(2x)=-0.02x

Answer 11

oh the x is by itself

Answer 12

i multiplied 2 and o.oo1

Answer 13

you wrote -0.01x^2 in the problem
in any event, find the derivative and then plug in the given value
f'(4000)=?

Answer 14

so f'(x)= -0.01(4000)+50

Answer 15

equals the answer

Answer 16

I'm not sure, you told me the function was a few different things, but at least the idea is right:
find derivative, plug in number

Answer 17

ok thanx
