ehehe ur question is that to answer all those questions on that page. right?
can u just do me a favor that to post all questions u have over here and dont worry i'll answer all after all its discuss freelyahummm...........thats exactly wat im doing but u are not replyig to the question I posted!
put both the values in the quadratic equationthanks bro! but why did u choose t= 1/5? it could be 1 as well cuz both when substituted equals 1 :S
what is the lower bound of " 2 meters correct to the nearest centimeter?"put both the values in the quadratic equation
in both cases u will get 0. the answer is both the values of t not only just one of them
1.995 metreswhat is the lower bound of " 2 meters correct to the nearest centimeter?"
READ EVRY PART OF THE QUESTION CAREFULLY!!!!tips for igcse math paper 22
bro why not 1.5 ? :O1.995 metres
can u send the link of the ppr and the question numberbro why not 1.5 ? :O
how did u knw its 1.995? i mean any way to work it out?
can u send the link of the ppr and the question number
here u go the 9th one,
and the 1 st one as well please!
look it says its to nearest cm. so while taking bounds u have to either add or subtract the half of what it is nearest tothanks but why are we taking the lower bound of 1 cm? also then why did u subtract it from 2?
genius! thanks man!look it says its to nearest cm. so while taking bounds u have to either add or subtract the half of what it is nearest to
if it was nearest to metre. than u would have subtracted 0.5m, right? its the same but only the units are changed. first to find lower bound u find what to subtract and it is half of what it is nearest to. in this case nearest to cm. take its half 0.5cm. now if u had to find upper bound u would have added this to 2 but u need lower bound so what u do is subtract it. but this is in cm and the actual measurement is in metres. so covert cm to m. 0.5cm=0.005m...
bro can u solve the 13 (b) part and 14 (b) part please!look it says its to nearest cm. so while taking bounds u have to either add or subtract the half of what it is nearest to
