Answer:
The answer is the last choice that is "None of these values will produce a mathematical error".
Explanation:
In this question, the above given choice correct because neither of the flowchart procedures could trigger a mathematical error. This error could not be induced by multiplication, addition and subtraction, and the only division by 15. It is the only divide by 0, that's why the above flowchart will produce a mathematical error.
Answer:
Firewall
Explanation:
A Firewall prevents outsiders from accessing corporate information the user does not want others to see. It could be in the form of a hardware or a software.
Most companies use this in order to keep confidential informations from the public. This is very important to prevent unauthorized access which could lead to different types of problems in the long run.
Answer:
Both Technicians are correct.
Explanation:
Remember that Ohm's Law its a relationship between Voltage (E), Current (I) and Resistance (R) in an electrical circuit. This relationship is defined by the following equation:

Each one of the letters could be called a variable. Now, also remember that the number of equations you have is equal to the number of variables unknown you could have.
In Ohm's Law you have 3 variables (E,I,R) and 1 equation. It means that you need to know 2 variables (Whatever 2 variables) to know the third.
Technician A says, in other words, that could calculate the Circuit current flow (I) knowing total circuit resistance (R) and total voltage (E). Note that Technician A knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:

Technician B says, in other words, that could determine the unknown resistance (R) knowing total current (I) and source voltage (E). Once again, note that Technician B knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:

It is concluded that both technicians are right.
Your easiest approach would be to write a WinForms application in C#. This is too much to put in an answer here. DM me if you need info.
Answer:
B It can seem boring.
Explanation:
The repetition of visual effects results in consistency, rhythm, and movement. However, too much repetition can cause monotony and boredom. And this is not good for you certainly. You are certainly going to lose the audience. And too much harmony in design as well in a similar manner causes boredom, or it can seem boring. And hence, the correct option here is B it can seem boring.
