Zolol [24]

Answer:

$\approx \frac{73}{12}\left(1 - \frac{1} {2\cdot73^2}\right)$

Step-by-step explanation:

$= \sqrt{\frac{73^2-1) 1}{12^2}} \\$

$= \sqrt{\frac{73^2}{12^2}\cdot\frac{73^2-1}{73^2}} \\$

$= \sqrt{\frac{73^2}{12^2}}\sqrt{\frac{73^2-1}{73^2}}\\$

= $\frac{73}{12}\sqrt{1 - \frac{1}{73^2}} \\$

$\approx \frac{73}{12}\left(1 - \frac{1} {2\cdot73^2}\right)$

Can anyone figure this out and explain? Thanks

The deepest point of the lake is -922, so to get to the surface of the lake you would need to add 922 feet.

The deepest point of the lake is 11,542 feet above sea level.

To find the surface of the lake add 922 to 11,542.

11542 + 922 = 12,464 feet
