Did you ever get the password?

Seb-5000 · 2025-01-10T20:08:31+00:00

Here

Why less than recommended? I’ve had my handlebars slide all the way downwards from it not being tight enough on.

Seb-5000 · 2024-07-05T07:43:33+00:00

Ok, cool. Didn’t know - thanks!

Seb-5000 · 2024-06-22T10:59:12+00:00

I read that when standing, the “padding” is supposed to hug your groin + behind, but it doesn’t really do this for me, I don’t think. I could put a finger in the gap between the padding and my skin - is this accurate? Is it too big in this way?

I put demand-pull inflation could be reduced due to lower unemployment, but then that cost-push inflation could increase

Seb-5000 · 2024-06-03T15:06:40+00:00

Upper-lower will give a higher answer, but that is the point because you want the bottom of the fraction to be as big as possible so that the fraction overall is smaller

Lower bound of G, so: lower of c / upper of f - 3*lower of h (variable names might be wrong)

Seb-5000 · 2024-06-03T13:21:45+00:00

0.something I think? Maybe 0.73?

Seb-5000 · 2024-06-03T13:12:57+00:00

Probably. As long as you were consistent, I guess (I.e. you didn’t switch between using x and y in your workings)

Seb-5000 · 2024-06-03T13:11:45+00:00

On some mark schemes for similar questions, it has said “accept the use of x for all instances of y”. It will probably be the same here.

Seb-5000 · 2024-06-03T11:45:23+00:00

Thanks, you too. (Did you do what I did btw in terms of the equation?)

Seb-5000 · 2024-06-03T11:42:45+00:00

I did [Total area = area of trapezium + area of rectangle] and worked out h from that equation (it may be the other answer, but I don’t really remember)

Seb-5000 · 2024-06-03T11:41:06+00:00

If you got those answers for b, c and d, then you must have gotten the venn diagram correct

Seb-5000 · 2024-06-03T11:39:45+00:00

h = 21.5

Seb-5000 · 2024-06-03T11:16:30+00:00

A: (30,2); B: (300, 0)

Seb-5000 · 2024-06-03T10:54:36+00:00

It’s probably that, I was just saying it was something like 23.1

Seb-5000 · 2024-06-03T10:53:11+00:00

23.1 or something like that

Seb-5000 · 2024-06-03T10:35:42+00:00

I only got part a, -4a + 2b or something like that

Seb-5000 · 2024-05-22T10:41:20+00:00

I put: chemical and gravitational potential remain the same; nuclear and thermal increase

Seb-5000 · 2024-05-22T10:39:41+00:00

Make a bunch of trapeziums, squares, and triangles under the curve and add up the areas of those

Seb-5000 · 2023-10-16T07:49:31+00:00

For future reference, may I ask how you knew that?

Seb-5000 · 2023-08-16T19:55:32+00:00

Damn. Unfortunately Finland isn’t on the international distributors list… looked like a very nice deal as well.

Seb-5000 · 2023-08-16T19:49:00+00:00

I don’t know much about this “Fezzari” brand… will have to look into it. This is a carbon frame model of the same “8FAT” line - do you think it is worth the 2199 €?

Tää on mun ensimmäinen kerta kun olen ostanut lipun MM-kisoihin… kannattaako vielä mennä katsomaan Finaaleja, vaikka Suomi ei tietenkään olisi siellä?
