Answer 1
Answer:
41) Yes, the relation is a function.
42) The domain of the function is [-2, 4].
43) The range of the function is [-1, 3].
Step-by-step explanation:
Relations and FunctionsA relation is a set of ordered pairs where each input (x-value) is associated with one or more outputs (y-values).
A function is a special type of relation where each input (x-value) is associated with exactly one output (y-value).
We can determine if a graphed relation is a function by applying the Vertical Line Test. It states that if a vertical line intersects the graph at more than one point, then the relation does not pass the test and is not a valid function.
As the given graph passes the Vertical Line Test, the relation is a function.

Domain and RangeThe domain of a function is the set of all possible input values (x-values).
The range of a function is the set of all possible output values (y-values).
From inspection of the given graph, the continuous curve begins in quadrant II at point (-2, 1) and ends in quadrant IV at point (4, -1).
The endpoints of the graph are represented by closed circles, which means that the corresponding x and y values are included in the domain and range.
Therefore, the domain of the function is the x-values of the endpoints: [-2, 4].
The minimum point of the curve is endpoint (4, -1) and the maximum point is (0, 3). Therefore, the range of the function is the y-values of the minimum and maximum points: [-1, 3].

It is necessary to design a bed packed with rectangular glass prisms that measure 1 cm and 2 cm high with a sphericity of 0.72, which will be used as a support to purify air that enters a gauge pressure of 2 atm and 40 C. The density of the prisms is 1300 kg/m^3 and 200 kg is used to pack the column. The column is a polycarbonate tube with a diameter of 0.3 and a height of 3.5 m. considering that the feed is 3kg/min and the height of the fluidized bed is 2.5 m. Determine the gauge pressure at which the air leaves, in atm.

Tina Phool enters into an investment plan with some local bigwigs. To get Tina to participate in the investment, people running the investment lie to Tina about several facts that are critical to the investment plan. Later, after suffering investment losses, Tina sues to rescind the investment contract on the basis of fraud. While Tina is on the stand, the attorney for the other parties asks her: "Ms. Phool, why did you enter this deal in the first place?" Tina says: "For one reason and one reason only, I admired these people tremendously and figured that any deal they were involved with was a deal I wanted in on too. The details didnt matter, if they were in, I was in."Question: Tina has just blown her fraud case, why? Please include analysis of facts and elements in your explanation
(2) A model rocket-car with a mass of 0.2 kg is launched horizontally from an initial state of rest. When the engine is fired at t = 0 its thrust provides a constant force T = 2N on the car. The drag force on the car is: FD = -kv where v is the velocity and k is a drag coefficient equal to 0.1 kg/s. (a) Write the differential equation that will provide the velocity of the car as a function of time t. Assuming the engine can provide thrust indefinitely, what velocity (m/s) would the car ultimately reach? (b) What would the velocity (m/s) of the car be after 2 seconds?

True or False: A piece of silver can be cut indefinitely into pieces and still retain all of the properties of silver Al Truc. All particles, including subatomic particles that make up the element, possess the proporties of the element. B) True. Atoms are the smallest units of matter, are indivisible, and possess the properties of their element. C) False. Once the pieces are smaller than an atom of silver, the pieces no longer retain the properties of silver D) False. Silver atoms are too small to possess the properties of silver E) False. As a piece of silver is cut into smaller pieces, the atoms begin to take on the properties of smaller elements on
An engineer employed in a well reputed firm in Bahrain was asked by a government department to investigate on the collapse of a shopping mall while in construction. Upon conducting analysis on various raw materials used in construction as well as certain analysis concerning the foundation strength, the engineer concluded that the raw materials used in the construction were not proper. Upon further enquiry it was found out that the supplier of the project was to be blamed. The supplying company in question was having ties with the company the engineer was working. So upon preparation of final report the engineer did not mention what is the actual cause of the collapse or the supplying company. But when it reached the higher management they forced engineer to *include* the mentioning of the supplying company in the report. Conduct an ethical analysis in this case with a proper justification of applicable 2 NSPE codes.
