Aradio active isotope decays according to the exponential decay equation where t is in days. round to the thousandths place. for the half life: the half life is the solution (t) of the equation : a2=ae−7.571t a 2 = a e − 7.571 t

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
