5. A 90 mg sample of a radioactive isotope has a half-life of 5 years. A function that related to the mass of the sample, m, to the elapsed time, t, is: a. m(t) = 5(90)ā b. m(t) = 90(5) c. m(t) = 90) t d. m(t) = 5(-)90 6. Which does not help to explain why you cannot use the laws of logarithms to expand or simplify log4 (3y — 4)? a. The expression 3y - 4 cannot be factored. b. The expression 3y - 4 is not raised to a power. c. 3y and 4 are neither multiplied together, nor are they divided into each other d. Each term in the expression does not have the same variable.
