Question

Hey!!



The graph below represents the distance of a dog from a trainer after a command is given.

Graph: https://media.education2020.com/evresources/3109/3109-01/3109-01-01/3109-01-01-assessment/3109-01-01-02.png

Which statement could describe the dog’s movement 5 seconds after the command was given?

1:The dog stopped to lie down and obey the trainer’s command.

2:The dog was running towards the trainer to receive a treat.

3:The dog was running away from the trainer to chase a squirrel.

4:The dog was stopped but began running towards the trainer.

Answer 1

Consider that the distance between the dog and the trainer is decreasing on the interval of 3 to 6 seconds therefore the time at 5 seconds falls into this interval what action is the dog doing?

Answer 2

I'm still a little confused

Answer 3

Rather than state that you're a little confused, why not ask some questions for clarification? Looking at the graph, note that when it's moving upward (has a positive slope), the dog is getting further away from its owner. Likewise, when the slope is neg., the dog is moving closer to its owner. What if the graph is horiz.?

Answer 4

Look at the graph again. When t = 5 sec, does the graph have a neg. slope, a pos. slope or a slope of zero?

Answer 5

at 5 seconds the graph graph is decreasing

Answer 6

So which of the given possible answers makes the most sense? Is the dog coming towards its owner, moving away from its owner, or maintaining the same distance?

Answer 7

Number 4, since in the first part, the dog is stopped then goes back to his owner?

Answer 8

We need to focus on time t = 5 sec., and ignore what happened earlier or later. At t = 5 sec, is the dog moving away from its owner, moving closer to its owner, or maintaining the same distance?

Answer 9

the dog is going towards his owner

Answer 10

Very good!
