1) 1/20 to the power of 4
2) 8 to the power of 2
3) 7.5 to the power of 3
hope this helped :)
The vector would have to be a scalar of (4,-1) in order to be parallel to it
so
4 = 8t -1 = 2t
t= 4/8 = 1/2
-1=2t
t= -1/2
Since the golden ratio is approximately 1.618033989 which fits what you provided, then rounded to the nearest thousandth would be 1.618
1/8 of 48 is 6, so Sarah cut 6 inches.
1/9 of 36 is 4, so Jane cut 4 inches.
6 is greater than 4, therefore, Sarah's piece is longer by 2 inches.
