Answer 1

I'll try doing it on my graphing calculator, but I got this wrong before so I'd like to check before I submit anything lol

Answer 2

*graphing calculator too small to show anything*
= =; *reopens desmo*

Answer 3

25 mph is correct :)

Answer 4

O: IT IS?

Answer 5

Wha- I don't even remember how I got that. I should just redo it just to commit to memory haha

Answer 6

Oh yeah... I got it off Wolfram because my idjit calculator can't show the graph properly = =;

Answer 7

hmm now i checked. It's little ambiguous.

Because at s = 25, we have N(s) = 73.333... and we can't have 73 1/3 cars, right lol

Answer 8

So we can check for intersections of N(s) and N = 73

Answer 9

Since 73 is greatest whole number under 73.333...

Answer 10

Answer 11

Yeah, I thought so too but it was the closest I got to an answer ; ;

Answer 15

Then you can check for intersections.

Answer 16

Uh I don't know what to do with this @ @ the graph is just sitting here in front of my face lol

Answer 17

You can click on line then gray dots will show up and then you can click on these dots to display point coordinates

Answer 18

Ah, I see.
These?

Answer 19

I'm guessing I find the midpoint of these guys? Lol

Answer 20

Ya, therefore answers are 22.722 and 27.506

I think you should put both as answer. This part is ambiguous.

Answer 21

Oh but... it says only one #, not "separate answers by commas" which it usually says for questions with more than one answer

Answer 22

So I'm not really sure o-o

Answer 23

Yeah, again this part is ambiguous.

In that case, I would go with 25 lol.

Answer 24

I believe 22.722 and 27.506 are correct answer, but i guess writer of this question didn't double-check or something lol.

Answer 25

So what you got?

Answer 26

Ah, my mother is nagging and using savage curse words at me :')

Answer 27

I think I'll stick with 25 first, check what it says :p

Answer 28

O: IT WAS RIGHT

Answer 29

Answer 30

That's really odd. I don't get the logic behind this either. o_O

Answer 31

It's less than highest speed, so technically it is correct lol

Answer 32

Oh, alright o:

Answer 33

Thank you for your help ! ♥ ^-^

Answer 34

Answer 35

No problem
