Let u = <7, -3>, v = <-9, 5>. Find 4u - 3v.
anonymous
  • anonymous
im going to do this one
UsukiDoll
  • UsukiDoll
careful while you can multiply the same way when subtracting it's u1-v1, u2-v2 because u = and v = u-v =

okay so far i got 4(7,3)-3(-9,5)
UsukiDoll
  • UsukiDoll
multiple the 4 with <7,3> - multiply 3 with <-9,5>
anonymous

<28,12>-<-27,15>
anonymous
  • anonymous
is it <1,3>
UsukiDoll
  • UsukiDoll
hmmm... <28-(-27)>,<12-15>
anonymous

okay what do i do for this one Let u = <-4, -3>. Find the unit vector in the direction of u, and write your answer in component form.
UsukiDoll
  • UsukiDoll
gotta find the formula or the format for component form. I need to finish my stuff. sorry.
