Write the vector u as a sum of two orthogonal vectors, one of which is the vector projection of u onto v, prove u = (-8,8), v = (-1,2)

a. (-0,5,1) + (-7.5,-9)
b. (-1,2) + (-7,-10)
c. (-1,2) + (-2,-1)
d. (1.6,-3.2) + (9.6,-4.8)

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

what i would say the best answer is a. 40.5

answer: i think one of the answer is $150 and $300?
