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.
14.6 lbs/4 weeks = 3.65 lbs /week
she lost 3.65 pounds each week
Since the shape is a square the sides are equal. Then we need to find x such that x * x = 169.
Sqrt(169) = 13
So x = 13
