+1, where x is her depth in meters
and y is the amount of pressure in atmospheres (atm). Which of these
statements are correct according to the model? Select TWO that apply.
A
For every 1 meter that the diver descends, the amount of
pressure on her decreases by 10 atms.
For every 1 meter that the diver descends, the amount of
pressure on her increases by 10 atms.
For every 10 meters that the diver descends, the amount of
pressure on her decreases by 1 atm.
For every 10 meters that the diver descends, the amount of
pressure on her increases by 1 atm.
E At sea level, the amount of pressure on the diver is atm.
10
F. At sea level, the amount of pressure on the diver is 1 atm.

Answer 1

According to the pressure model equation, for every 10 meters that a diver descends, the pressure increases by 1 atm. At sea level, the pressure is 1 atm.

Step-by-step explanation:

The equation pressure (y) = 10x + 1 models the pressure on a diver as she descends. Here, x is the depth in meters and y is the amount of pressure in atmospheres (atm). According to this equation:

• For every 10 meters that the diver descends, the pressure on her increases by 1 atm (since the coefficient of x is 10).
• At sea level, where x is 0, the pressure on the diver is 1 atm (since y = 10(0) + 1 = 1 atm).

Therefore, the correct statements according to the model are:

• For every 10 meters that the diver descends, the amount of pressure on her increases by 1 atm.
• At sea level, the amount of pressure on the diver is 1 atm.
