Question

find the unit vector in the direction of u write in linear combination of the standard unit vectors i and j

Answer 1

i got 1/sqrt26i+5/sqrt26j

Answer 2

is the vector u <1,5> ?
if it is then you are right, except the sqrt is in the denominator

Answer 3

yes i forgot to say that

Answer 4

and heres the multiple choice
A.1/6i+5/6j
B.1/sqrt26i+5/sqrt26j
C. i+j
D. 1/26i + 5/26j

Answer 5

oh in that case you are right, looks like they didn't rationalize the denominator

Answer 6

oh what would it be if i rationalized the denominator?

Answer 7

sqrt26/26 (i +5j)
