Swapping rows alters the sign of the determinant:
Multiplying a single row by a scalar scales the determinant by the same amount:
Then
If you are looking for an expression it would be x < 4 and the < has a line underneath for less than or equal to. If this is right could I possibly have brainliest? Hope this helped!! :)
Absolute value can never be negative
Absolute value: | |
| 1 | ( ) 5
1 ( ) 5
1 < 5

Answer:
9.6
Step-by-step explanation:
When we are adding decimals we try 2 add them like normal integers, but in the end we add the decimal in the same place as it was in the beginning
so 62+34=96 and there's a decimal in the tenths place so its 9.6
Answer:
45 degrees
Step-by-step explanation:
Here, we want to get the value of the acute angle
From the question, we have it that the sin of the acute angle equals its cosine
Recall;
cos A = sin (90-A)
Hence, if A is 45, then Cos A and Sine A will be the same
This means the value of theta which is the acute angle is 45 degrees
