Answer 2

Therefore, Mr. Mole's burrow lie 7 meters below the ground.

Given,

A linear function consisting of 2 terms, one is dependent on time and the other one is independent of time, i.e.,

A = -2.3t - 7

• The dependent term -2.3 indicates that the altitude of Mr Mole decreases by 2.3 meters every minute.
• At t = 0, A = -2.3(0) - 7 = 0 - 7 = -7.  (Negative sign indicates the value is below the ground level of 0 meter.

        The constant term - 7 is the altitude at t = 0, because at t = 0

Thus, Mr. Mole's burrow lie 7 meters below the ground.
