Answer:
The first option 
.
Step-by-step explanation:
To have exactly 2 real and two non real solutions, the degree of the polynomial must be a degree 4. Degree is the highest exponent value in the polynomial and is also the number of solutions to the polynomial. This polynomial ha 2 real+2 non real= 4 solutions and must be 
. This eliminates the bottom two solutions.
In order to have two real and two non real solutions, the polynomial must factor. If it factors all the way like
This means x=0, 10, -10 are real solutions to the polynomial. It has no non real solutions. This eliminates this answer choice.
Only answer choice 1 meets the requirement.
Answer:
- $4.65
- $69.75
Step-by-step explanation:
How much money she makes from each bracelet:
9-4.35=$4.65
How much money she makes from the 15 bracelets:
4.65 x 15= $69.75
3(6-8)^2 +8÷2
3(-2)^2 +8÷2
3(4)+8÷2
12+8÷2
12+4
16

Answer:
1
Step-by-step explanation:
<em><u>Use the clues given.</u></em>
We know that 5% is equal to 5/100 or .05. Using one of those numbers, we can find what the answer is.
<u><em>Multiply by 20.</em></u>
In this case, I will be using .05, just because it is the easiest. So, if we multiply .05 by 20, we will get 1.
Hope this helped,

Answer: The population of the town in 2015
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form)
x= years after 2006
A = population after t years
Replacing with the values given:
p(9) = 8,963 (1.03)^9
Since the years passed between 2006 and 2015 are 9 ( x), the equation represents the population of the town in 2015.
Feel free to ask for more if needed or if you did not understand something.
