Let a=⟨−1,−2,3⟩a=⟨−1,−2,3⟩ and b=⟨−5,4,−4⟩b=⟨−5,4,−4⟩. Show that there are scalars ss and tt so that sa+tb=⟨−18,20,−22⟩sa+tb=⟨−18,20,−22 ⟩ You might want to sketch the vectors to get some intuition.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
