You are new in town and need to know how the streets flow in order to efficiently get around town. Your math friend decides to help you out by giving you a matrix that represents the directions the streets run in between important buildings. However, you would feel better in looking at a directed graph. On a separate sheet of paper, draw a directed graph to represent the following matrix. Which buildings have two-way streets between them?

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
