Search this up "If the point z (6,-9) is rotated 180° around the origin, what are the new coordinates of point Z ?"
Free points also respond if you did it.

Z' (-6,9)

Step-by-step explanation:

When a point is rotated around 180 degrees, the negative and plus values are simply switched, so positive 6 becomes -6, and -9 became positive 9.

Hope this helps :)

(-6, 9)

Step-by-step explanation:

For 180 degrees, the rule is (x, y) > (-x, -y)

we rotate the point (6,-9) > (-6, --9) =(-6, 9)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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
