A chemist has 50 grams of the isotope gold-196 which has a half-life of one week. This means that the amount of the sample decreases by half each week. Determine the equation and the graph of its solution set to represent the amount of gold-196 over the course of several weeks.

answer: it is 1: 47 pm

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
