Pls help For z = -3 + 5i, evaluate
(Note: denotes the conjugate of z.)

Step-by-step explanation:

♨Rage♨

34

Step-by-step explanation:

Here z = -3 + 5i and the complement of this is

        z-comp = -3 - 5i.

Multiplying these two quantities together, we get

9 -25i²   =    9 + 25  =  34

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
