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,
Answer:
33
Step-by-step explanation:
With the equation 4x, the x represents side length. Since we are given side length of 5/7, then the equation becomes
perimeter = 4 × 5/7
p= 20/7
p= 2 6/7 units
Answer:
angle 1 and angle 3 are congruent
Step-by-step explanation:
Angles supplementary to the same angle are congruent. Here both angles 1 and 3 are supplementary to angle 2, so angles 1 and 3 are congruent.
_____
If you like, you can get there algebraically:
m∠1 + m∠2 = 180
m∠3 + m∠2 = 180
Subtract the second equation from the first:
(m∠1 + m∠2) - (m∠3 + m∠2) = (180) - (180)
m∠1 -m∠3 = 0 . . . . simplify
m∠1 = m∠3 . . . . . . add m∠3
When angle measures are the same, the angles are congruent.
∠1 ≅ ∠3
