A particle moves along the x-axis so that at time t greater or equal to 0 it’s position is given by x(t)= t^3 + 7t^2 -24t. determine the velocity of the particle at t= 1.

Situation: . find the substance's half-life, in days. round your answer to the nearest tenth. a 11 gram sample of a substance that's used to treat thyroid disorders has a k. value of 0.1247. enter the correct answer n - noekt done no - initial mass (at time t = 0) n - mass at timet k a positive constant that depends on the substance itself and on the units used to measure time t= time, in days
