The decay rate of a certain chemical is 9.5% per year. What is its half-life? Use the exponential decay model P(t) = poe-k-1 where k is the decay rate, and PO is the original amount of chemical. The half-life of the chemical is Year. (Round to the nearest integer.) Solve for x. log 3(x + 1) - log 3X = 2 Select the correct choice below and, if necessary, fill in the answer box to complete your choice. The solution is x = (Simplify your answer. Type an integer or a fraction. Use a comma to separate answers as needed.) The equation has no solution. Find the logarithm using the change of base formula.(log 515 log 515 Round to four decimal places as needed.)
