Answer:
B. -1
Step-by-step explanation:
A graph can show you that the expression approaches -1 as x approaches 2π.
The limit is -1.
__
The expression evaluated at x=2π is 0/0, an indeterminate form. This suggests that L'Hopital's rule is applicable. Applying that, we have ...
lim = (f'(2π) -f'(x))/(x-2π)' = -cos(x)/1
Evaluated at x=2π, this is ...
lim = -1
Answer:
I would say the third option is correct

Answer:
lol i failed miserably so hopefully this helps you not be like me
Step-by-step explanation:
Answer:
in the step-by-step
Step-by-step explanation:
okay one thing is that you labelled wrong since you have to label D', D", D'" (you just labelled with one for all of them)
a you reflected across the y-axis wrong
-it would be that D' (-2,6), E' (-2,3), F' (-5,3)
b you rotated correctly
this gets more confusing since you labelled the triangles wrong, but I hope this first part helps
For the expression to be factor-able the Discriminant , has to be greater or equal to zero
ax^2 + cx + b = 0
c^2 - 4 ab >= 0
(-3)^2 - 4 * 1 * b >= 0
9 - 4b >= 0
9 >= 4b
b <= 9/4 (2.25)
Pick any value in that range for ex:
0 , 2, -3, -6
