Solution
The equation provided is , and the table contains some missing values that we need to fill in. Let's analyze the table step by step.
From the image, we can see:
- One row and one column are labeled and respectively.
- The values and are present, and we need to calculate the corresponding missing value.
Step-by-Step Calculation:
-
When , substitute it into the equation : So, when , . This is one of the missing values in the table.
-
When , we need to find . Set in the equation: Solve for : So, when , . This is the other missing value in the table.
Final Filled Table:
0 | -9 |
4.5 | 0 |
