Jaira is completing construction of a regular hexagon inscribed in a circle, as shown below: What should be the next step in her construction? Circle A is drawn with point B marked on the circle with arcs C and D marked on circle A with a compass set to segment AB.

Construct a line perpendicular to line AB to create four congruent quadrants.
Draw another circle from point B with the same radius as her original circle.
Construct another point E by placing her compass at point D.
Draw arcs above and below line AB to show where the angles meet.

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
