Joe is a chemical engineer whose plant discharges heavy metals into the local river. By the test authorized by the city governme

nt, the amount of heavy metals is under the legal limit imposed by the city. By a new and more accurate test, the discharge is above the legal limit, that is, the discharge is in violation of environmental rules. Joe argues with his manager that the plant should reduce its discharges to comply with the newer and more accurate test.
The case contains a conceptual issue insofar as:


A.the issue is whether present emission rates constitute a violation of city regulations.


B.the issue is what is meant by “violation.”


C.the issue is how Joe should balance his obligations to his employer against his obligations to city residents.


D.the issue is whether the heavy metals presently emitted by the plant pose a threat to the health of the community.

Answer:

B probably

Explanation:

Because the prompt doesn't specify what sort of violation it could be anything maybe when they release the metals during the day and so on.

Which is an alloy made up of iron and carbon and has high compressive and tensile strength?
Digiron [165]

Answer: Steel is an alloy of iron with typically a few percent of carbon to improve its strength and fracture resistance compared to iron. Many other additional elements may be present or added. Stainless steels that are corrosion and oxidation resistant need typically an additional 11% chromium.

Find the differential and evaluate for the given x and dx: y=sin2xx,x=π,dx=0.25
Sedaia [141]

By applying the concepts of differential and derivative, the differential for y = (1/x) · sin 2x and evaluated at x = π and dx = 0.25 is equal to 1/2π.

<h3>How to determine the differential of a one-variable function</h3>

Differentials represent the <em>instantaneous</em> change of a variable. As the given function has only one variable, the differential can be found by using <em>ordinary</em> derivatives. It follows:

dy = y'(x) · dx     (1)

If we know that y = (1/x) · sin 2x, x = π and dx = 0.25, then the differential to be evaluated is:

y' = -\frac{1}{x^{2}}\cdot \sin 2x + \frac{2}{x}\cdot \cos 2x

y' = \frac{2\cdot x \cdot \cos 2x - \sin 2x}{x^{2}}

dy = \left(\frac{2\cdot x \cdot \cos 2x - \sin 2x}{x^{2}} \right)\cdot dx

dy = \left(\frac{2\pi \cdot \cos 2\pi -\sin 2\pi}{\pi^{2}} \right)\cdot (0.25)

dy = \frac{1}{2\pi}

By applying the concepts of differential and derivative, the differential for y = (1/x) · sin 2x and evaluated at x = π and dx = 0.25 is equal to 1/2π.
