Asubmarine is at the surface of the ocean. it begins its descent at a rate of 100 feet per minute. write a linear model in the form d(t)=mt+b where d(t) represents the depth of the submarine relative to sea level, in feet, after t minutes into its descent. be sure to include "d(t) =" in your answer. (note: when the submarine is below sea level, its depth is a negative quantity)

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.

d(t)=-100t

Step-by-step explanation:

d is the independent variable and t is the dependent variable. The rate of descent has to be negative so that the altitude decreases compared to sea level. The initial sea level is 0.

the statemwnt is the company makes small and large snow cone cups.

large=it holds more then the small

small=it holds less then the large

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
