3. What are two ways that a vector can be represented?

Considering a vector in some vector space we have

This is the component form. I don't like that way. It is probably used in high school, but

is preferable because the inner product on is defined to be

You can also write it using linear form such as

4.

For this question, I think you meant

vectors

Once

Considering that the dot product is

and the norm of is

and the norm of is

Thus,

here

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
