We know that
• Mt. Everest height was 8,850 meters in 1999. This is the initial condition.
,
• The rate is 5cm per year or 0.05 m per year.
Based on the given information, we express the following equation.
![y=0.05x+8850](https://img.qammunity.org/2023/formulas/mathematics/college/zesk2lgrx3drdmo9ekox5ryedio2ykbqr8.png)
Where x is years and y is height in meters,
Now, in year 0, x = 0.
![\begin{gathered} y=0.05(0)+8850 \\ y=8850 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/vkfgeov1el9sxmz5o3x9l7shfjeihsg0q8.png)
Therefore, Mt. Everest height in year zero is 8,850 meters.
