Answer:
Step-by-step explanation:
(3x^2 + 2x - 3)(x-1)
Expanding the brackets
x(3x^2 +2x - 3) -1(3x^2 +2x -3)
3x^3 +2x^2 -3x -3x^2 -2x + 3
3x^3 - x^2 - 5x + 3
It would be (A) , the point 9 (38.9) only needs another point to be a whole tenth .
Answer:
40:70 becomes 20:35 which becomes 4: 7.
The answer is 4:7
Step-by-step explanation:
Here are the outcomes. You could also a tree diagram for this:
There are 49 outcomes for this problem. Therefore, 7/49 possible probability that 2 could be orange. To check if i'm correct, use a tree diagram or a compound principle.

Answer: 15x^(7/3) - 8x^(7/4) + x + 9000</h3>
=========================================================
Explanation:
If you know the cost function C(x), to find the marginal cost, we apply the derivative.
Marginal cost = derivative of cost function
Marginal cost = C ' (x)
Since we're given the marginal cost, we'll apply the antiderivative (aka integral) to figure out what C(x) is. This reverses the process described above.
D represents a fixed constant. I would have used C as the constant of integration, but it's already taken by the cost function C(x).
To determine the value of D, we plug in x = 0 and C(x) = 9000. This is because we're told the fixed costs are $9000. This means that when x = 0 units are made, you still have $9000 in costs to pay. This is the initial value. You'll find that all of this leads to D = 9000 because everything else zeros out.
Therefore, we go from this
to this
which is the final answer.
