Answer:
± 8i
Step-by-step explanation:
note that = i
using the rule of radicals
• × ⇔ , hence
= ±
= ± × = ± 8i

Answer:
Step-by-step explanation:
We are given that vector space of all symmetric matrix
M(R)={
where a,b,c,d,e,f,g,h,i}
Let A=
A'=
A is symmetric
Then A'=A
=
a=a , e=e, i=i
a-a=0 , e-e=0, i-i=0
b=d, c=g ,f=h
Hence, the matrix
Therefore, the basis are
There are three elements to generate an element of vectors of all symmetric matrix matrix
=
Answer:
The answer is A
Step-by-step explanation:
Down 2 right 3. You can figure this out for other problems like this by choosing any point on the graph and following the slope. It's down because the 2 is negative and 3 is positive to it goes to the right.
Answer:
(7, -1)
Step-by-step explanation:
point X has the coordinates
( |-1-3| +3, |-9 - -5| + -5) = (4+3, 4-5) = (7, -1)
