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:

Explanation:
Vector Multiplication code:
Vector_multiplication.c file contains C code.
See attachment no 1 attached below
Classification of Algorithm: For creating elements in vector c of size n, number of scalar multiplications is equal to n. The size of original two vectors scales directly with the number of operations. Hence, it is classified as O(n).
I am not too familiar with the Python language, but the algorithm would be something like this:
1. create a variable for the sums of the number
2. read in how many numbers the user wants to enter (let's call it N)
and then create a for loop:
for N times
read in the next number
increase the sum variable by that number
Hopefully this helps!
