Answer:
4
Step-by-step explanation:
Short Answer CRemarkYou may think there is no way to resolve this. Either of the first two look like they might work and you cannot be sure what you will get with the last two unless you know.
The answer is one of the last two. The equation cannot have just one or even a large number of complex numbers. When you are factoring a polynomial, the number of complex numbers must be even.
The complex root you have is x + 2i. Its partner is x - 2i
The complete equation would be
y = (x - 2i)(x + 2i) (x - 2)(x + 4)(x - 4)

Answer:
Common ratio, r=-3
Recursive Formula

Step-by-step explanation:
The formula for the geometric sequence:
is given as:

<u>Common Ratio</u>
Dividing the next terms by the previous terms, we obtain:

Therefore, the common ratio of the sequence, r=-3
<u>Recursive Formula</u>
We observe that the next term,
is obtained by the multiplication of the previous term. f(n-1) by -3.
Therefore, a recursive formula for the sequence is:

Answer:
<h2>a. 40 + 20 + 3 + 6</h2>
Step-by-step explanation:
Points scored by Hessa is as shown below;
Round 1 = 43 points
Round 2 = 26 points
Total points for both rounds = 43 + 26 = 69 points
To determine the sum she could use to add the points together, we must select the sum that will give us the same total of points for both rounds i.e 69 points.
The Round 1 score (43 pt)can also be expressed as (40+3) points
The Round 2 score (26 pt)can also be expressed as (20+6) points
The sum she could use to add the points together will be (40+3)+(20+6)
which is also equal to 40 + 20 + 3 + 6 = 69points
Hence, option a is correct
