Answer 1

The equation Q = 0.91 * (4)^t represents exponential decay.

The starting value is the coefficient of the exponentiated term, which is 0.91.

The decay rate is the base of the exponentiated term minus 1, which is 4 - 1 = 3.

The continuous decay rate is found using the formula k = ln(r), where r is the decay rate.

k = ln(3) ≈ 1.0986

Therefore,

a = 0.91

r = 3

k ≈ 1.0986
