I^89 simplified. Complex number.

Semmy [17]3 years ago

This problem can be simplified by remembering that since i= \sqrt{-1}, we have i^{4}=(-1)^{2}=1. Then we have i^{89}=i^{88+1}=i^{88}i^{1}=(i^{4})^{22}i=(1)^{22}i=i.

Answer:

The equation is 18h=378

h=21

So first you have to set up the equation

so if she makes 18 dollars an hour the first part of the equation would be 18h

She made 378 dollars in one week so now the equation is 18h=378

Sliva [168]

Answer:

Step-by-step explanation:

GIRL! You should add diagrams to these types of questions. It would really help

That 10cm does not mean point C is 10cm. It means the line AB is 10 cm in total.

And since point C is the midpoint, which means that point C cuts the line AB in half, that makes AC = 5cm

Construct a truth table for the logical operator NOR.
Rasek [7]

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.
