Answer: Rounded to the nearest tenths place, it is 3.7 meters.
Step-by-step explanation:
Using the above formula, let's multiply 2.5 times 2.5 and 4.5 times 4.5.
2.5 times 2.5, or 2.5 squared, equals 6.25
4.5 times 4.5, or 4.5 squared, equals 20.25
Now, let's subtract 20.25 minus 6.25. The difference is 14.00.
What is the square root of 14? It is 3.74165739. Let's round that number to the nearest tenths place.
What is the number in the tenths place? It is 7. And--what is the number that comes after it? Well, it is 4. Therefore, the 7 should stay a seven. If the number next to the tenths place was five or greater, then we should add one.
The augmented matrix of the system of equations is
The system of equations is given as:
-2x + 2y - z = 13
-3x - y + z = 7
-x + 3y - 2z = 0
Remove the variables x, y and z
-2 2 -1 13
-3 -1 1 7
-1 3 -2 0
Express as matrix
Hence, the augmented matrix of the system of equations is
