DF has midpoint E(1, -3). if ID(0, 2), what are the coordinates of F?

F is at (2, -8)

Step-by-step explanation:

use the midpoint formula:  (sum of x-values/2, sum of y-values/2)

let (x,y) = coordinate of pt F

(0+x/2) = 1;  x = 2

(2+y/2) = -3;   2 + y = -6;   y = -8

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
