Which phrase represents the graph below? a. a person riding a ferris wheel b. a descending paper plane c. both of the above d. neither of the above

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.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
