First you write what the vectors are, then you subtract z from w by subtracting their corresponding values <-4-3,1-4>= <-7,-3>, then to get subtracting the next answer you subtract w from z which is <3--4,4-1> = <7,3>

Answer:
A penny/coin is 0.75 inches in diameter.
A.
When 288.7 billion pennies are lined up they will form = 216.525 billion inches.

Now assuming 365 days in a year, this becomes
