Please help explanation if possible

What properties allow transformation to be used as a problem solving tool

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = 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

What is the correlation coefficient between the variables? round to three decimal places. enter your answer in the box
