Let u=4i-j and v=5i+5j. Decompose u into two vectors u, and u2, where u, is parallel to v and u, is orthogonal to v. Write your answers in the form a i+bj.

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings

60: 45 =12: 9 =4: 3 so the answer is 4: 3
