    its quite simple: 1) make 3 eqns. (since there are 3 variables) 2) they are: a) -33+x=y b) x+y=z c) y+z=18 3) then replace y with -33 + x i.e. x + -33 + x= z and -33 + x + z =18 4) reorder and make it into a simultaneous eqn. i.e. 2x-z=33 and x +z = 51 5) solve the eqn. 6) u will get the value...

    10 ci) (this method is very long bt not sure of any other ones) 1) put any value of n...say 4 2) equate it to the number of diagonals for that shape i.e in this case 2 3) repeat one and 2 with any other value of n 4) turn it into simultaneous eqn. 5) solve it 6) p should be 2 and q should be 3...

    if u hv the paper printed out it would be easier for u. 1) the way to do it is to draw a line parallel to the y - axis from where both the graphs intersect, till the line meets the x axis 2) one should meet the x axis at around -4.5 and the other at around 1.3 3) make an inequality from those 2...

    LOL u seem to be going over the top XD just do this: 1) leave ur calculator aside (its unnecessary for the question) 2) create the 2 eqns. a) 2 + d=e b) d + e =10 3) reorder eqn. (a) i.e. d-e = -2 4) solve the simultaneous eqn. 5) 2d = 8 is what u should get 6) so d = 8/2 which is 4 7) put the...

    the height for 22-24 is straight forward just 26/10= 2.6 (the 10 comes from 115/11.5) then for 10-20... the gap between 10 and 20 = 10 so we divide 10 by 2 which was the gap between 20 and 22 then multiply the ans=5 by 10 that = 50 thus we divide 35/50 = 0.7 the last one is similar... the gap is...

    coz d is way below the trough and the wave would never even go there!

    Physics, Chemistry and Biology: Post your doubts here!

    its because a is the crest and c is the trough therefore b should be the answer as it is in the middle :D hope it helps!! and best of luck!!!
