Answer:

Step-by-step explanation:

Sure.
The rule says that "The 'n'th term is 2^n + 1. "
You're asked to find the 5th term, so plug '5' into the rule in place of 'n'.
The 5th term = 2^5 + 1
2^5 = 2 x 2 x 2 x 2 x 2 = 32
The 5th term = 32 + 1 = <em>33</em> .
Answer:
Yes. You can make a tree diagram with each subject at the top and the periods as the branches or with the periods at the top and each subject as a branch. Both ways provide the same number of outcomes, 18
Step-by-step explanation:
For this case we have the following quadratic equation:

Where:

By definition, the discriminant of a quadratic equation is given by:

We have to:
Two different real roots
Two different complex roots
Two equal real roots
Substituting the values we have:

So, we have two different complex roots
Answer:
Two different complex roots
