Question

find a vector a that has the same direction as <-8,9,8> but has a length of 3

Answer 1

64 + 81 + 64= 209

sqr209 = about 14.46

3/sqr209 times -8 = -1.66

3/sqr209 times 9 = 1.87

<-1.66, 1.87, 1.66>

magnitude =approximately sqr(1.66^2 + 1.87^2 + 1.66^2) = sqr9 = 3

<-24/sqr209, 27/sqr209, 24/sqr209>
