vectors

[buoyant swallow]

for b why is vector BD = 2/3 BC if it’s 2/5 x

and what is going onnnn in c

Yeah Vector BD should be 2/5 of BC

[harsh sparrow]

If 2 lines are parallel what can you say about their gradients?

[buoyant swallow]

but its supposed to be 2/3

thats why im confused

[buoyant swallow]

theyre the same

[late forge]

No it's supposed to be 2/5 because its a ratio
If I share 10 sweets between person A and B at a ratio of 2:3, how many sweets would each person get?

To work it out your turn it into a fraction

Person A would get 2/(2+3) of the sweets

Person B would get 3/(2+3) of the sweets

[harsh sparrow]

Ye so in part (c) which two lines have the same gradient

[buoyant swallow]

thats what i was thinking

but my teacher said 2/3

and explained why but i forgot her explanation

[buoyant swallow]

AP and OC

so AP = k OC

idk how to find AP

[late forge]

She probably said it by accident

[buoyant swallow]

nah

she explained it

cause i asked her why its 2/3 and. not 2/5

[harsh sparrow]

Did ur teacher say to do it using vectors cus u can do this with coordinate geometry instead

[buoyant swallow]

this was the working we did @harsh sparrow

[harsh sparrow]

Alr

So OP is a multiple of which vector
