Answer:
8 9.8 - 6.4n
9 15 - j/2
Step-by-step explanation:
8
2.8 - 4.4n - 2n +7
= 2.8+7 -4.4n -2n
= 9.8 - 6.4n
9
11 + (-3) - 1/8 j - 3/8 j +7
= 11 - 3 - 1/8 j - 3/8 j + 7
= 11 - 3 + 7 - 1/8 j - 3/8 j
= 15 - 4/8 j
= 15 - j/2
Answer: The required value would be 0.000013.
Step-by-step explanation:
Since we have given that
0.001 % of 
As we know that
To remove the % sign we should divide it by 100.
Mathematically, it would be expressed as

Hence, the required value would be 0.000013.
