During a winter storm, snow falls at a steady rate. At the start of the storm, there was already some snow on the ground from a previous storm. Let t represent time in hours, and let s represent the number of inches of snow on the ground.

Which sketch models this situation?

can you help me @SolomonZelman

anonymous · Answer

its a

brucebaner · Answer

why is it A

anonymous · Answer

*  there was already some snow on the ground

brucebaner · Answer

is it A @SolomonZelman

anonymous · Answer

so the graph its not going to start from zero

anonymous · Answer

and *snow falls at a steady rate   so it would increase linearly

solomonzelman · Answer

you know there was already some snow to begin with, so there is a positive y-intercept.
And you know that the snow during storm goes up, (not dfown).

anonymous · Answer

you get it @brucebaner?

jhannybean · Answer

It is also increasing at a steady (constant) rate, so the slope of the line does not change as drastically (you could eliminate some options using this too)

brucebaner · Answer

so its B

jhannybean · Answer

B represents a storm that is coming to an end by decreasing snowfall. We are talking about from the beginning of a snowstorm.

solomonzelman · Answer

well... the steady rate means that it is a linear equation. doesn't mean a very big slope. (not neccessarily).

brucebaner · Answer

A

solomonzelman · Answer

yes, A... it has been given away at the begininning, and not that I would call that a feat.

jhannybean · Answer

Elaborate upon your previous post, @SolomonZelman ?

alexandervonhumboldt2 · Answer

A

solomonzelman · Answer

I mean that steady doesn't mean a very high slope. Just the English word doesn't mean that it is very high, but more like permanent (in this case).
or you are going on something esle?

brucebaner · Answer

thx @SolomonZelman and @Jhannybean,@Ldaniel

jhannybean · Answer

Oh I thought you meant my analysis of the question was wrong (steady = constant), so I asked for clarification.

solomonzelman · Answer

:) your analysis is better than mine....
