Plz find the missing value when given the modulus. 1. (picture) (in the first quadrant)

Step-by-step explanation:

Given that the modulus of z = 48+bi is 50

Also that the point lies in the I quadrant.

Hence b can be positive only

We have from the definition of modulus of complex numbers that

Square both sides to get

Hence we find that the square root is positive for +14

So is the answer.

step-by-step explanation:

in which figure is point g a centroid

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
