Suppose x and y are nonzero vectors in an inner product space. Show that x and y are orthogonal if and only if ||x+y|| = ||x-y||
harkovskaia [24]

Answer:

Step-by-step explanation:

Suppose x and y are nonzero vectors in an inner product space.

Let us assume that x and y are orthogonal

i.e. innter product is 0.

This implies dot product of x and y is 0

Then x.y =0

i.e. x^2+y^2 +2x.y = x^2+y^2-2x.y\\||x+y||=||x-y||

Proved

Converse part:

Let ||x+y||=||x-y||

Square also would be equal

||x+y||^2=||x-y||^2\\||x||^2+||y||^2+2x,t=||x||^2+||y||^2-2x.y\\x.y =0

Hence inner product of x and y is 0

Ray Cupple bought a basic car costing $26,500.00, with options costing $725.00. There is a 6% sales tax in his state and a combi
Amiraneli [1.4K]

The total cost would simply be the sum of all the costs incurrent by Ray Cupple.

The costs are:

car = $26,500.00

options = $725.00

estate = car + options = $27,225.00

tax = 0.06 ($27,225.00) = $1,633.50

fees = $50.00

 

Hence the total cost is:

 

total cost = car + options + tax + fees

total cost = $26,500.00 + $725.00 + $1,633.50 + $50.00

total cost = $28,908.50

 

Answer:

C. $28,908.50
