Modulus dari vektor begin mathsize 14px style a with rightwards harpoon with barb upwards on top equals open parentheses table row cell negative 16 end cell row cell negative 8 end cell end table close parentheses end style adalah
 

Jawaban:

Diketahui:

 begin mathsize 14px style a with rightwards harpoon with barb upwards on top equals open parentheses table row cell negative 16 end cell row cell negative 8 end cell end table close parentheses end style

Gunakan rumus phytagoras untuk menentukan besar vektor tersebut

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell vertical line a with rightwards harpoon with barb upwards on top vertical line end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell square root of left parenthesis negative 16 right parenthesis squared plus left parenthesis negative 8 right parenthesis squared end root end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell square root of 256 plus 64 end root end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell square root of 320 end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 17 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank comma end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 8 end table end style

Jadi modulus vektor tersebut adalah 17,8
