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:

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

( Since,
)

Hence, we get:

Answer:
I think BC is 45°÷2 Or 12÷2
Step-by-step explanation:
so the answer is 15° or 6
The total means add so,
42 + 75 + 189 + 301 + 728 = 1,335
Answer is C.
