\

a.

\

Write a recursive formula to represent $\"\"$ .

\

Let $\"\"$ .

\

The pressure increases for each foot below sea level $\"\"$ .

\

$\"\"$ represents the human body at $\"\"$ foot below sea level.

\

The pressure exerted on the human body at $\"\"$ foot below the sea level is $\"\"$ .

\

$\"\"$ represents the human body at $\"\"$ foot below sea level.

\

The pressure exerted on the human body at $\"\"$ feet below the sea level is $\"\"$ .

\

Recursive formula to represent the pressure at $\"\"$ feet below the sea level is $\"\"$ .

\

$\"\"$

\

b.

\

$\"\"$ represents the human body at $\"\"$ foot below sea level.

\

The pressure exerted on the human body at $\"\"$ foot below the sea level is $\"\"$ .

\

$\"\"$ represents the human body at $\"\"$ foot below sea level.

\

The pressure exerted on the human body at $\"\"$ feet below the sea level is $\"\"$ .

\

$\"\"$

\

c.

\

The difference between the terms is $\"\"$ .

\

This sequence can be represented by a linear function that has slope $\"\"$ .

\

The equation with the slope $\"\"$ is $\"\"$ .

\

The pressure exerted on the human initially is $\"\"$ where $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ in $\"\"$ .

\

$\"\"$

\

Find pressure at $\"\"$ feet below the sea level.

\

Substitute $\"\"$ and $\"\"$ in $\"\"$ .

\

$\"\"$

\

Therefore, the water pressure at $\"\"$ feet below the sea level is $\"\"$ .

\

$\"\"$

\

a. The pressure exerted on the human body at $\"\"$ feet below the sea level is $\"\"$ .

\

b. The pressure exerted on the human body at $\"\"$ feet below the sea level is $\"\"$ .

\

c. The water pressure at $\"\"$ feet below the sea level is $\"\"$ .
