I am not 100% sure but I am pretty sure the answer is (3,-1,4)
Given:
Two vectors are:


To find:
The projection of u onto v.
Solution:
Magnitude of a vector
is:

Dot product of two vector
and
is:

Formula for projection of u onto v is:




On further simplification, we get



Therefore, the projection of u onto v is
.
Y+5=-11
-5 -5
Y= -16
Answer:-16
Answer:
5 × a + b
Step-by-step explanation:
