Answer:
Step-by-step explanation:
The idea of Gauss Jordan row reduction is to reduce the matrix form of the system of equation to reduced row echelon form using some elementary row operations. There are three operations that can be performed on the rows, namely;
1. swap two rows.
2. multiply one row by a nonzero number
3. add or substract the multiple of one row to/from another
For the given exercise, the matrix form is given as
These are the operations that are performed to get the reduced row echelon form.
1. swap Row1 and Row3
2. Row2 + 12*Row1 and Row3 + 12*Row1
3. -1/156 * Row2
4. Row1 + 12*Row2 and Row3 + 143*Row2
5. -156/3837 * Row3
6. Row1 + Row3
The matrix is now reduced to the row echelon form.
From Row1, the element in the first column is equal to 1 and the last column is equal to zero, this implies that .
From Row2, the element in the second column is equal to 1, the third column is equal to 143/156 and last column is zero, this means that
Similarly from Row3, .
Putting these together,
Answer:
If he lets the account go for 90 days, he will
pay an interest of $60
Step-by-step explanation:
Here, we want to calculate the interest Garvin will pay if he lets the account go for 90 days
Since 90 days is greater than 60 days, this means that he is going to pay a 12% annual interest rate
Thus, mathematically , the amount to pay will be;
12% of $500
= 12/100 * 500 = 6000/100 = $60
Answer:
L
Step-by-step explanation:
The y coordinate of the image is 6 more than that of the preimage.
Answer:
h=2A/b
Step-by-step explanation:
Try to isolate the variable H. Multiply by 2 on both sides to get rid of the fraction. This gives us 2A=bh. Now, divide both sides by B to get h by itself. h=2A/b is your answer.
