<h3>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.
Answer:
Therefore we come to a conclusion that,
Gregory's Rectangle is in Area.
Step-by-step explanation:
Given:
Fiona draws a 24 centimeter rectangle.
Gregory draws a 24 square inch rectangle.
To Find:
Whose rectangle is in area = ?
Solution:
Rectangle has a dimension as
Length and Width which are in meters, centimeters, inches, feet, units, etc.
For Area
here units are getting Multiplied so it becomes
unit × unit = unit² = square units
m × m = m² =square meter
inch × inch = inch² =square inches
Hence Area is calculated in square units.
Therefore we come to a conclusion that,
Gregory's Rectangle is in Area.
