7

Answer 1

Answer #1

Solution :- if u and v are two vectors such that they form the side of a parallelogram the,

u+v and u-v form the diagonal of a parallelogram.

we have given u = <-3,-2> and v = <13, 0 >

Hence, D1 = u+v = < -3,-2 >+< 13, 0 >

D1 = u+v = <-10 , -2 >

and length is = sqrt{ 100+4} = 2 sqrt(26)

Also D2 = u-v = <-16 ,-2>

so length is = sqrt{ 256+4 } = sqrt(260) =2 sqrt(65)
