Yachts in the Sydney to Hobart Race need to satisfy a set criteria to be placed in the 2
various divisions. If one of the divisions required a yacht to weigh 28 tonnes ± 20 kg,
calculate the percentage error allowed in this measurement to 1 significant figure.
was the ± 20 part about??... i just done 20/28000 which is 0.0007
the answer is 0.07%
Also --- A gardener has 16 metres of fencing with which to enclose a rectangular vegetable patch.
(i) If the length of the rectangular vegetable patch is x metres, show that the area of 2
the rectangular vegetable patch is given by A = 8x – x2.
How do you 'show' it?
