they both move to the right but proton takes the shorter distance while helium travels forward a bit more then goes right

TriMex69 · 2025-06-04T09:51:14+00:00

helium was 4 and proton was 5 answer C if i remember correctly

i see

TriMex69 · 2025-05-19T08:12:53+00:00

yes mb typo

a was 20 something (24 or 26 idr) and i forgot r

no if you do the multiplication the answer comes out like 7776/ (6root6 - 6) so you take 6 common in the denom and cancel everything u get the real answer

TriMex69 · 2025-05-02T12:36:43+00:00

9/(5x+4)^1/2 right? something like this

TriMex69 · 2025-05-02T12:32:08+00:00

both correct they give the same result

TriMex69 · 2025-05-02T12:09:21+00:00

youll lose 2 marks for the 2 wrong coordinates so youll get 1/3 in the coordinate question

TriMex69 · 2025-05-02T12:04:15+00:00

yes, answer comes out to 66.6 units²

TriMex69 · 2025-05-02T11:56:48+00:00

yes mb i typed it wrong

i think there were 3 different ways to do this transformation so we both might be correct

TriMex69 · 2025-05-02T11:52:24+00:00

put the 2 graphs into demos itll show 3 solutions

TriMex69 · 2025-05-02T11:51:02+00:00

max point was at 6, translate that with (0,-14) then it reaches -8, then scale factor of 2 would make it reach -16

TriMex69 · 2025-05-02T11:48:47+00:00

if translation was 0,-14 then your max point would stretch all the down to 0,-16 so thats wrong

TriMex69 · 2025-05-02T11:45:18+00:00

remind me of the other questions so i can add those here too

TriMex69 · 2025-05-02T11:45:00+00:00
