Answer:
No.
Step-by-step explanation:
If it is geometric the quotient of the terms and the previous term will be a constant.
213 / 31 = 6.871
4459 / 213= 20.93
These are not equal so the sequence is not geometric.
The answer is B., valid because people were chosen randomly
This would make it a valid survey
Hope this helps!

Answer:
Vertical angle=9.5°
Time to reach maximum height = 1.24seconds
Step-by-step explanation:
The maximum distance x is reached when rope swings to a maximum height, maximum height is gotten from the equation KE= 1/2MU^2 = MgH = MgL= Mgl(1- cos theta.
Where theta is the vertical angle, U=2m/s and L= 15m
2gl -2glcostheta=U^2
2gl U^2=2gl cos theta
But theta= Acos(1- U^2)/2gl
Acos(1-/(2×9.8×15)
Theta =9.5°
Maximum height li given by
Lsintheta
But X= UxT
T=X/UX= Lsintheta/U = 15sin9.5 /2 =1.24seconds
Alright, this question is a bit confusing, but hopefully this will help:
Remember that Log(a) B = C is actually a^C = B. (Just imagine "a" as the little number that is first written after "Log.")
So here, I think Log(9) 0.877 = "x." And you want the value "x."
9^x = 0.877, which is all I've got, cause I don't really know what this "change of base rule" is. But I hope I helped.
It is TRUE, so shade on the SAME side as (0,0)
