How do you convert displacement time graph into distance time graph?
Displacement is distance from starting point. If the object is always travelling in the same direction then they are the same. If the object turns round, the distance would still be increasing, however the displacement would be decreasing at the same rate.
What does it mean when something is directly proportional?
Directly proportional means that both variables increase or decrease at the same time.
What is the round-to-even rule?
The rounding rule which is usually taught in schools is that if the next digit is 1, 2, 3 or 4 then you round down while if it is 5, 6, 7, 8 or 9 then you round up - 0 is not rounded, of course. This means that if the "next" digit is random, then you round down less often than up: this introduces a upward bias in the result. The solution is to round 5 up half the time and down half the time. It would be possible to do this randomly but then the rounding is not reproducible: someone doing the same sum as you could round numbers differently and so come to a different answer.The IEEE (Institute of Electronic and Electrical Engineers) standard 754 is to round 5 up or down so that the new last digit is even. This is the round to even rule.
