Answer:
Step-by-step explanation:
The question to be solved is the following :
Suppose that a and b are any n-vectors. Show that we can always find a scalar γ so that (a − γb) ⊥ b, and that γ is unique if 
. Recall that given two vectors a,b a⊥ b if and only if 
where 
is the dot product defined in 
. Suposse that 
. We want to find γ such that 
. Given that the dot product can be distributed and that it is linear, the following equation is obtained
Recall that 
are both real numbers, so by solving the value of γ, we get that
By construction, this γ is unique if 
, since if there was a 
such that 
, then
Step-by-step explanation:
2x-10x= -4y-y
-8x= -5y
cancel (-) on both sides we get
8x=4y
Answer:

1/3 times 1/2 = 1/6
Class I
Trailer hitches are divided into different classes on the basis of the weight that they will be supporting. The classes are Class I - V, after which the classes are Xtra Duty and finally the Commercial Duty class, which has the ability to support 20,000 lbs.
