A manufacturer has fixed costs of $16,000 per month and can produce w widgets at a cost of 0.1w^(2) + 20w. How many widgets shou
musickatia [10]
Consider c as the cost of the widget so that our given equation is
c = 0.1w^2 + 20w
Take the derivate of the equation.
d/dt (c = 0.1w^2 + 20w)
dc/dt = 0.2w + 20
Given dc/dt = $16000 per month, the number of widgets would contain:
16000 = 0.2w + 20
-0.2w = 20 - 16000
-0.2w = -15980
w = 79900 widgets

Hey all you math geniuses can you help me with this question that should be easy
kenny6666 [7]

Answer:

(B) \frac{-3}{x}

Step-by-step explanation:

Since \frac{-3}{x} consists of division of -3 with a variable, therefore it is not a polynomial, rest all other options are polynomial as they involve addition,multiplication with variables.

C(x) = 5x + 2

This is because at 1 hour it only cost 7 dollars, so it should only have 2 added to the end.
