vector gcse question

[hoary saffron]

always makes me drop marks and i need help on thjis

[austere quest]

what is JN?

[hoary saffron]

6b?

[austere quest]

yeah good

how could we get to JK?

We'll worry about getting to JM in a minute

[hoary saffron]

i was thinking 10b - 7a

[austere quest]

Great

so if you know M is the midpoint of JK

what is JM?

[hoary saffron]

not sure thats where i messed up

[austere quest]

what does midpoint mean?

[hoary saffron]

middle point between the two points

[austere quest]

soooo

middle is a VERY big hint

if we know the whole of JK

that's 10b-7a

and you know M is the midpoint

what would you have to do to JK to adjust it to get to JM instead

[hoary saffron]

half 10b-7a

[austere quest]

yes!

so that is...

[hoary saffron]

5b-3.5a

[austere quest]

yeah lovely, I'd recommend just leaving as a fraction

[hoary saffron]

oh ok

[austere quest]

fractions r ur friends

is what my teacher always says lmao

[hoary saffron]

yeahh lol i just try make it a decimal whenever its easy

thought it would get me more marks before but i just stuck to the habit

[austere quest]

I'd only say use decimals when it's nice ones in probability

otherwise just always stick to fractions; they're much easier to work with

[hoary saffron]

ok thx
