What is multiplying monomials of exponents ?If a person multiply monomials, the first thing to do is to multiply the coefficients and later on one can multiply the variables through the addition of the exponents.
Conclusively, One needs to know the fact that if a person multiply monomials using the same base, the person can also add their exponents and this is referred to as Product of Powers Property.

Cite three examples to describe how an engineer ensures that his or her designs are made to scale.
↪It is exactly defined by those three words.
1. Process - it is a set of activities that turns input into wanted outcome.
2. Design - a representation of the looks, functions and functionality of your product (outcome)
3. Engineering - is the use of science in order to achieve goals
So here is how I would define engineering design process:
It is a set of activities, powered by physics and mathematics in order to create optimal solution.
I think the most important word here is optimal .
In engineering design it is all about the limits and boundaries. You are limited by budget, materials, space, time...
So you can never create the best solution. You can only do optimal.
Optimal is a solution which will meet all (or the most) limits.
If you are to design a car engine, the best design would probably be the one that does not use any fuel.
But that is not possible, right, since you are limited by the law of conservation of energy. So the optimal solution would be an engine which will use the less fuel as possible.
Of course, there are best practices for the design activities mentioned above (workflows, decision points, phases...)
This is the process model that works for me:
1. You get the task (problem).
2. Set the boundaries
3. You get an idea for solution (brainstorm)
4. Create a mathematical model for solution (describe by numbers)
5. Create a physical model for solution
6. Concept design (sketch)
7. Drawings (3D model)
8. Simulate (if simulations fails, return to point 6)
9. Prototype and test
After this, your solution will be implemented and used.
You will get feedback.
You (or someone else) will improve your solution (product)
Your old solution will "die" (or be recycled)
New solution will take it's place.
And that is what is called product life cycle. Important part of engineering design process.

Describe the limitations of the assembly model in representing the physical automaton.
Answer:
They are expensive, time-consuming to make, the needing to be rebuilt if destroyed, and sometimes it is impossible to build a large enough model
Explanation:
They are costly, labor-intensive to manufacture, must be rebuilt if they are destroyed, and occasionally it is impossible to construct a large enough model.
What is automaton?An automaton is a relatively self-operating machine or control system designed to perform a series of tasks automatically or respond to preset commands.
The bell strikers in mechanical clocks are an example of an automaton that, to the uneducated eye, appears to be propelled by its own volition.
The expression has a long history of use to describe automata that move like real, breathing people or animals and are created to entertain or impress people.
Therefore, they are expensive to produce, labor-intensive to rebuild if they are destroyed, and occasionally impossible to build a large enough model.

Technician A says test lights are great for performing simple tests. Technician B says you can use a test light to check SRS circuits and computer circuits. Who is correct
The technician that is correct about either testing lights for simple tests or to check SRS Circuits is; Technician A.
Which Technician is Correct?First of all it is pertinent to note that test lights are generally small bulbs that are turned on by the voltage and current flowing through the circuit in analog circuits.
Now, the two values of voltage and current are high and sufficient to light up the bulb. However, in digital circuits, the current is very small in the order of milliamps, and as a result there is not enough power to turn on the lights.
Thus, we can conclude that Technician A is correct.

Select three types of lines that engineers use to help represent the shape of a design in a sketch.
object lines
leader lines
center lines
extension lines
dimension lines
hidden lines
Answer:
object, hidden, and center lines
Explanation:
Among the given alternatives, we prefer to dimension to visible lines.
When creating technical drawings, dimensions are typically placed on visible lines. Visible lines represent the visible edges or outlines of an object or part. These lines are used to depict the physical features of the object that are visible to the eye. By dimensioning to visible lines, we ensure that the measurements are accurately associated with the visible features of the object.
This helps to provide clear and unambiguous information about the size and location of the features being dimensioned. Dimensions on hidden lines or center lines may not accurately represent the physical dimensions of the visible features and can lead to confusion or misinterpretation. Therefore, visible lines are the preferred choice for dimensioning in technical drawings.
