Propagating the error through a multi-variable function three variables are measured to be a = 12 . 3 ± 0 . 4, b = 5 . 6 ± 0 . 8 and c = 89 . 0 ± 0 . 2. calculate the mean and uncertainties in z when it b and c z = a − b , via (iii) the relations: z = a − b a + b , 2 × is related to a , z = a + b , (ii) z = ab c , (v) z = arcsin b a , (vi) z = a × b (vii) z = ln ( abc ) , (viii) z = exp ( abc ) , z = a + tan b c , (x) z = 10 abc

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

is there a graph
