The total cost to produce x handcrafted wagons is c(x) = 110 + 7x - x^2 + 2x^3. find the marginal cost when x = 8.
1016
1126
485
375

The marginal cost when x=8 is:

                          375

We know that the marginal function for a cost function C(x) at x=a

is given by:

   C'(x) at x=a

Here we have the cost function C(x) as:

Now we find the derivative of C(x) with respect to x.

i.e.

( Since,

 )

Hence, we get:

if you need just tell me and i will come to the rescue.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
