That is acceptable.I proved the particle was moving downwards by showing that the horizontal position was > the midpoint (half of the endpoint)
Is this an acceptable method?
well done, but you also need to have a reasonable assessment rank/final mark.I think I got 100 then. How do they distinguish the state rankers?
I think an explanation was required.carrotsticks, for the probability question, if i got the answer by stating that 7C5 - 6 = 6C4 (just by speculation using calculator), will I still get 1/1?
Definitely not.would i lose marks for newtons approximation method if i just said x=2.57 without radians?
Very hard to say for this one.carrotsticks, for the probability question, if i got the answer by stating that 7C5 - 6 = 6C4 (just by speculation using calculator), will I still get 1/1?
ftfy.Good job carrotsticks. Please can you do it for 2016 HSC too ?
Plot Twist: The mountain is actually a hill.That's a very short mountain then.
It's too late now for you, but for this reason I always tell my students to verify their answer with what makes sense in real life. Is your answer reasonable? If not, double check it.
So if I got a 62m high mountain, I'd immediately be suspicious.
