Vector a = 3i + mj, vector b = 2i - nj and vector c = ni + 8j. if a and b is perpendicular to each other and b and c are parallel to each other, find m and n.

May be you know it or not a two dimensional vector can be represented by a complex number.Why i have written this statement you will just know when you will see its solution

a = 3i + mj and  b = 2i - nj are perpendicular to each other ,so their dot product

will be zero.

j

vector b = 2i - nj and vector c = ni + 8j are parallel to each other.j

mn = 6

so m=6/4i

m=3/2i

m=3i^{4}/2i

m = 3i^{3}/2

m= -3i/2 as(i^{4} =1, i^{3} = -i[/tex][/tex]

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
