Answer:
A   B   A NOR B 
F   F        T
F   T        F
T   F        F
T   T        F
Step-by-step explanation:
The logical operator NOR produces a result that is the negation of the logical operator OR.
The truth table for the logical operator NOR can be obtained by the negation of the results of the truth table for the logical operator OR.
Let A and B be the the logical values (or inputs). The operator OR produces a value of true if and only if at least one operand is true. The truth table for OR is:
A   B   A OR B
F   F       F
F   T       T
T   F       T
T   T       T
So, the truth table for NOR is:
A   B   A NOR B 
F   F        T
F   T        F
T   F        F
T   T        F
Notice that the negation of OR (which is NOR) is obtained by changing the F by T and the T by F in the column of the results.
This table can also be writen with 0 instead of False and 1 instead of True.
 
        
             
        
        
        
Add the exponents and keep the same base. Then reciprocal it and change the sign of the exponent. Then the value of the exponent expression is 0.5.
<h3>What is an exponent?</h3>
Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.
The exponent expression is 2³ × 2⁻⁴ can be simplified.
Add the exponents and keep the same base. Then we have 
2³ × 2⁻⁴  = 2⁽³⁻⁴⁾
2³ × 2⁻⁴  = 2⁻¹
Then find the reciprocal and change the sign of the exponent.

The value is 0.5.

C)
10hrs will get around 105 salaries
90hrs get 840+105=945
95 hours get 945+(105/2)=997.5
100 hours get 945+105=1050
