Mr. mole left his burrow that lies below the ground and started digging his way deeper into the ground, descending at a rate of 1.8 meters per minute. after 5 minutes, he was 13.5 meters below the ground.
let a(t) denote mr. mole's altitude relative to the ground a (measured in meters) as a function of time "t" (measured in minutes).
write the function's formula.

Step-by-step explanation:

Mr. Mole's digging can be described by a linear model of general equation:

Where "m" is the rate at which he descends. Note that since the function A(t) measures his altitude relative to the ground, the rate "m" must be negative (m=-1.8).

The constant "c" is his starting position. To find this value, assign the given data at t= 5 min to the equation above

Therefore, the function A(t) is described by the following formula:

b
