Question

A 46 gram sample of a substance that's a by-product of fireworks has a k-value of 0.1368.

N = N0e -kt

N0 = initial mass (at time t = 0)

N = mass at time t

k = a positive constant that depends on the substance itself and on the units used to measure time

t = time, in days


Find the substance's half-life, in days.

Round your answer to the nearest tenth
