<h2>Answer:</h2>

The marginal cost when x=8 is:

                          375

<h2>Step-by-step explanation:</h2>

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:

C(x)=110+7x-x^2+2x^3

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

i.e.

C'(x)=0+7-2x+6x^2

( Since,

\dfrac{d}{dx} x^n=nx^{n-1}  )

C'(x)=7-2x+6x^2

Hence, we get:

C'(8)=7-2\times 8+6\times (8)^2\\\\i.e.\\\\C'(8)=7-16+384\\\\C'(8)=375

Which collection of three side lengths will not form a triangle
dezoksy [38]

Answer:

Any collection of lengths (a, b, c) which do not satisfy the triangle inequalities.

Step-by-step explanation:

Any collection (a, b, c) which do not satisfy the triangle inequalities. The inequalities:

a + b > c

b + c > a

a + c > b

You will need to test all of your options on the three inequalities above. If any one of the three fails, the collection won't work.
