32 goals for question 1

Around 2160 minutes for q2

I can’t remember the values of d, e and f but it was a translation by vector (13/10) I think

37800 for the LCM of 5A and 7B

Something like 4/3 and -3/2 for the x coords where gradient is 4 (don’t take my word on that I can’t fully remember what I wrote)

And the transformation was an enlargement I think scale factor 3 centre (0, 2)

33.6cm for the perimeter of the shape

y = -5/2x - 1/2 for the equation of AB

x = 2 for the composite function q and 2.5 was the value excluded from the domain

For simultaneous equations x = 0.5 and y = 1.5

n = -2.5 for the indices question

Around 62.3% for the percentage profit

For vectors I got 6:5

For the histogram the missing frequencies in the table were 25 and 60, and the value of one small square on the frequency density scale was 0.1

For the sequence 6 marker I got X = 57

For the pentagon one I got r = 3.45cm

For the frustum I got 5090cm²

Did anyone else get the same answers?

Great! I got the same answers for the sequence and the frustum (but I didn't complete the pentagon one unfortunately )

I think I got the same answer for the pentagon one and I can’t even remember what I put for the sequence one, but I’m pretty sure I got like 4000 and something for the frustum one…? Not sure if they are right tho 😂

I got the same for the frustum and sequence but I got like 1.2 something for the pentagon

What did others get for the vector ratio q?

I also got 4000 something

Did you do like area of trapezium x 4 cuz there is 4 sides and then area of square

vector 5:6

sequence i got 57

pentagon i got same ^^

frustrum i think i got 5070

omgi think i got 5000 smth for the frustum

For the pentagon one I got r = 3.45cm

For the frustum I got 5090cm²

Did anyone else get the same answers?

I got exactly the same except the frustrum

Original post by NellLFE

anyone get 4810 for the frustrum?

I think i did

Original post by themonke

I got 6:5

I got the same

(Original post by Amm32)Did you do like area of trapezium x 4 cuz there is 4 sides and then area of square

yeah idk if it's right tho but i got 507 i think? for the the top square of the frustum??

Anyone else get that?

Yep I got exactly that!

If someone is interested in how to solve the vector question here is a picture of how to do it: https://prnt.sc/wgsT4sarTOBL

I think the smaller square had side lengths of 13cm so the area was 169cm²
