Given:
The matrix multiplication
To find:
The order of resulting matrix.
Solution:
We know that, if order of first matrix is 
and the order of second matrix is 
, then the order of these two matrices is 
.
We have,
Here, the order of first matrix is 
and the order of the second matrix is 
. So, the order of the second matrix is 
. It is also written are 2 by 1.
Therefore, the correct option is A.
You must “reverse” the inequality sign to make the statement true: When you multiply by a negative number, “reverse” the inequality sign. Whenever you multiply or divide both sides of an inequality by a negative number, the inequality sign must be reversed in order to keep a true statement.
It's pretty much simple. Since we can factor a polynomial by its zeros, lets write one of degree nine :
X(X-1)(X-2)(X-3)(X-4)(X-5)(X+1)(X+2)(X+3)= X^9-9X^8+6X^7+126X^6-231X^5-441X^4+944X^3+324X^2-720X
This polynomial is of degree 9 and has exactly 5 strictly positive zeros : 1, 2, 3, 4, 5
And it has 3 negative zeros : - 1, -1, - 3
And it has 0 as a zero too.
There is also this one :
(X-1)(X-2)(X-3)(X-4)(X²+1)(X+1)(X+2)(X+3) = X^9-4X^8-13X^7+52X^6+35X^5-140X^4+13X^3-52X^2-36X+144
It has 4 positive zeros : 1, 2, 3, 4.
It has complex zeros : i and - i
3 negative zeros : - 1, - 2 , - 3
Good Luck
Answer:
A. point F (3,5) B. 5 units C. 10 units
Step-by-step explanation:
Answer:
18 units in all
Step-by-step explanation:
one side is 5 then 2 and another 2 then 3 and another 3 then a third 3 so 5+2+2+3+3+3=18
