For five days, several hikers walk the distance and direction described by the vector
⟨5, –2⟩ each day. The next day, they walk the distance and direction described by the vector ⟨–1, 8⟩. At the end of the six-day trip, what is their bearing from their starting location?

  94.76°

Step-by-step explanation:

Assuming the coordinates are <E, N>, the total distance from the start is ...

  5<5, -2> +<-1, 8> = <5·5 -1, 5(-2) +8> = <24, -2>

These coordinates represent a vector south of east, so the bearing measured clockwise from north will be greater than 90°. The reference angle (with respect to a north-south line) will be ...

  arctan(24/2) = 85.24°

The bearing is 180° -85.24° = 94.76°.

sorry man i accidentally pressed yes my bad

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
