Sam's friend planted a kudzu plant in Sam's backyard. The original area the plant occupied was 0.5 square feet. It is expected that the area the plant will occupy will grow continuously at a rate of 13% per day. Question A: Write a model to predict the area the plant will occupy at any given time. Be sure to define all variables. Question B: Sam's friend planted the Kudzu on June 1st. How much area will the plan occupy on June 15th? Round your answer to the nearest tenth. Question C: Sam didn't notice the plant's presence until it was too late and now it's taken over his entire 400 square foot backyard. How long did it take Sam to notice the presence of the plant?
