Complex roots occur when b^2 - 4ac is negative.
So we have (-6)^2 - 4.1.k < 0
-4k < - 36
k > 9
Answer: Ok, so this question is confusing to me as well, and I have this same question on school. So when I get the answer, I will try to explain it to you the best I can. :) God Bless. Stay :D
Step-by-step explanation:
$35.71
Step-by-step explanation:
Since Griffin’s General Store is having a 30% off sale on fans, it simply means that fans are paying for (100%-30%)= 70%.
Let the original price be x;
Therefore, 70% of x equal to $25;
70/100x = 25
0.7x = 25
x = 35. 71
(There ya go)
Answer:
a. √9
Step-by-step explanation:
a. √9 = 3
b.√15 = sqrt(5*3) cannot be simplified
c. √18 = sqrt(9) sqrt(2) = 3 sqrt(2) cannot be simplified farther
d. √20= sqrt(4) sqrt(5) = 2 sqrt(5) cannot be simplified farther
a is the only answer that is a rational number
