Step-by-step explanation: Horizontal dilation. If A is between 0 and 1 then the effect on the graph is to contract by a factor of 1/A (towards the y-axis). ... For example, replacing x by x/0.5=x/(1/2)=2x has the effect of contracting toward the y-axis by a factor of 2. If A is negative, we dilate by a factor of |A| and then flip about the y-axis.
Element x decays radioactively with a half life of 8 minutes. if there are 450 grams of element x, how long, to the nearest tenth of a minute, would it take the element to decay to 37 grams?
