Working entirely with the information given in the question,
it's really hard to tell what 'RAW', 'Z', 'T', or '%ile' represent.
So, r' (the new r) becomes kr, and h'=h*k,
so V' = pi * (r')^2*h' = pi * (r*k)^2*(h*k) = pi*r^2*h*k^3 = V * k^3
Convinced?
I would say neither of the above.
A is incorrect because in the graph, the curves get shorter over time, and if you were riding the same Ferris wheel, the curves would be the same size the whole time, because the Ferris Wheel would stay the same shape and height.
B is incorrect because the height increases then decreases and increases and decreases, etc, while the description is simply, a descending paper plane.
C is incorrect because it wouldn't be both of the above since they were both wrong.
4n - 3= -2n + 9
add 3n to both sides
4n= -2n +12
add 2n to both sides
6n= 12
divide both sides by 6
n= 2
Check:
4n-3=-2n+9
4(2)-3= -2(2)+9
8-3= -4+9
5=5
Hope this helps! :)
