Line segment AB is reflected across the y-axis. The resulting segment, A'B', is translated 7 units left and 2 units down. How is the length of AB affected by the reflection and the translation? A) A'B' is twice the length of AB. B) A'B' is half the length of AB. C) A'B' is the same length as AB. D) More information about the coordinates is needed.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

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

for future students the answer is b
