Find matrices of orthogonal projections onto all 4 fundamental subspaces ofthe matrixa =1 1 11 3 22 4 3note, that really you need only to compute 2 of the projections. if you pick an appropriate 2, the other 2 are easy to obtain from them. (recall, how the projections onto e and e⊥ are related).

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

is it like a multiple choice? if so then i need the multiple choice so i can get and understanding on what the answers is so that i can explain it to you
