Answer:
- The graph of the function is attached below.
- The x-intercepts will be: (2, 0), (-2, 0)
- The y-intercept will be: (-20, 0)
Explanation:
Given the function

As we know that the x-intercept(s) can be obtained by setting the value y=0
so

switching sides

Add 20 to both sides


Dividing both sides by 5





so the x-intercepts will be: (2, 0), (-2, 0)
we also know that the y-intercept(s) can obtained by setting the value x=0
so



so the y-intercept will be: (-20, 0)
From the attached figure, all the intercepts are labeled.
Answer:
a. A only
Explanation:
When air, is in excess of allowable amounts, it can cause the system to operate at pressures that are higher than normal. This means that the recycled refrigerant is operating at high pressure. Thus Technician A is correct.
However, Technician B is incorrect because unlike reclaimed refrigerants where the process strip the refrigerant of impurities making it to meet the standards of a new refrigerant, the recycled refrigerant is not as pure as it's contaminants are only reduced.
Therefore, only technician A is correct.
Answer:
the CPU utilization decreases as the degree of multiprogramming is increased.
Explanation:
The fundamental concept is that allocating a process with too few frames causes too many and frequent page faults. This implies that the CPU does not perform any useful work and thus its utilization would decrease drastically. In this case, the long-term scheduler, in a bid to improve the utilization of the CPU, would load more processes into the memory so as to increase the extent of multiprogramming. As a result, there would be more decrease in the utilization of the CPU, leading to a chained reaction of higher page faults, which is then followed by a corresponding increase in the multiprogramming degree, usually known as thrashing.
