    That they're parallel.
    couldn't they have also been part of the same vector as well though as we didn't get the precise point of S

    So what did people get for that table question. Where is had like x/4 or something cant even remember 2nd to last Q.

    lol no

    that point S also satisfies the vector OT (?) so it is the intersection of the two lines.
    I'm not sure, i wrote that they intersect but Im pretty sure I was wrong, others said it was parallel, so I just presumed they were right, my bad.

    I got 69 degrees, don't remember my working though.

    And Pi is a number 3.14...

    Is it's 25pi = 25*3.14, so you can't just take it away from 100, without first dealing with Pi. BIDMAS or whatever it's called.
    could you not dsay 100- 25pie

    It was direct proportion i think when y=k/x squared as y was directly proportional to the square of x. So you had to find the value of k and then substitute it in.

    ffs I knew direct proportion why did they put it like that.

    No it asks for it simplified so it would be 25(4-pi) ...............

    Why is that simplified? That's factorised

    It probably confused you as it wasn't put into words 'y is directly proportional...' as they just wrote x (proportional sign thingy) 1/x squared

    But whether you expand a factorised form it is simplified
