Answer:
d(t) = -100t
Step-by-step explanation:
The general expression for the linear model is:
Since the submarine already starts at sea level, b=0:
The constant "m" is the rate at which the submarine descends in feet per minute. Considering depth as a negative quantity, m=-100
The linear model that represents the depth of the submarine relative to sea level, in feet, after t minutes is d(t) = -100t.
