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:
7.92 cm²
Step-by-step explanation:
Area of Trapezium :
- 1/2 x (a + b) x h
- 1/2 x (4.8 + 8.4) x 1.2
- 0.6 x 13.2
- 7.92 cm²
Answer:
125.0272
Step-by-step explanation:
7 (1.14)^22
Each hour it grows 14%. This means after 1 hour, it has grown 7*1.14. After two hours 7*1.14 (1.14) or 7*(1.14)^2, etc so after 22 hours use equation above to solve.
