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.

Step-by-step explanation:
These are just ratios. They are both essentially doubling
Answer:
x > -1 or x < -1
Step-by-step explanation:
For the first equation, 5x-29 > -3
Step 1: Move the constant to the right and change its sign
5x-29 > -34
5x > -34+29
Step 2: Calculate the sum
5x > -34+29
5x > -5
Step 3: Divide both sides of the inequality by <em>5</em>
5x > -5
x > -1
<em><u>Answer</u></em><em><u>:</u></em> -1
For the second equation, 2x+31 < 29
Step 1: Move constant to the right and change its sign
2x+31 < 29
2x < 29-31
Step 2: Calculate the difference
2x < 29-31
2x < -2
Step 3: Divide both sides of the inequality by 2
2x < -2
x < -1
<em><u>Answer</u></em><em><u>:</u></em> x < -1
