Answer:
1's or 0's
Step-by-step explanation:
Thinking process:
The matrix property: det (AB) = det (A) det (B)
Adding the multiple of one row to another will be equivalent to left multiplication by an elementary matrix.
For example, let E be some form of matrix such that:
n x n matrix, and so E is an n x n elementary matrix which acts as an operator which adds l copies to the i row and to row j.
Applying the same row operation to B results in the matrix AB.
This, the matrix, without the loss of generality becomes:
therefore, as seen from the matrix, the triangular matrix of the product is diagonal.
The matrix will have a diagonal so the determint of A, det A = 1
thus: det (AB) = det (A)det(B) = 1 det (B) = det (B)
Answer:
6 years old
Step-by-step explanation:
Since her twin brother is the same age as her, you are looking for two equal factors whose product is 36. The square root of 36 is 6, so the answer is they are both 6 years old.
Answer:
d≈15.92
Step-by-step explanation:
Using the formulas
C=2πr
d=2r
Solving for d:
d= C/π = 50/π = 15.91549
<u>Step-by-step explanation:</u>
A good example that comes to find is the fuel gauge found on a car, this gauge allows the driver to monitor the percentage of fuel left in the car.
Let's assume the car fuel tank has a capacity of 100 liters. if the indicator is showing half-filled, to illustrate this in percentage it is written as 50% while decimal it will be 0.5.
