For x^3-11x^2+33x+45 , we can make it an equation so <span>x^3-11x^2+33x+45=0. Next, we can find out if -1 or -3 is a factor. If -1 is a factor, than (x+1) is factorable. Using synthetic division, we get
x^2-12x+45
___ ________________________
x+1 | x^3-11x^2+33x+45
- (x^3+x^2)
_________________________
-12x^2+33x+45
- (-12x^2-12x)
______________
45x+45
-(45x+45)
___________
0
Since that works, it's either B or D. We just have to figure out when
</span> x^2-12x+45 equals 0, since there are 3 roots and we already found one. Using the quadratic formula, we end up getting (12+-sqrt(144-180))/2=
(12+-sqrt (-36))/2. Since sqrt(-36) is 6i, and 6i/2=3i, it's pretty clear that B is our answer
Answer:
C
Step-by-step explanation:
A = 1 = Point
B = 2 = Line
C = 3 = Plane
I hope this helps and that you have a great day :)
The answer might be A because (time between airline arrivals MUST be more than 2 minutes) in letter A it shows that time is more than the 2 minutes hope this helps =)
I GUESS IT'S CCCCCCC , RIGHT?
The answer to your question is B.
