Julian is using a biking app that compares his position to a simulated biker traveling julian's target speed. when julian is behind the simulated biker, he has a negative position. julian sets the simulated biker to a speed of 20\,\dfrac{\text{km}}{\text{h}}20 h km 20, space, start fraction, k, m, divided by, h, end fraction. after he rides his bike for 151515 minutes, julian's app reports a position of -2\dfrac{1}{4}\,\text{km}−2 4 1 kmminus, 2, start fraction, 1, divided by, 4, end fraction, space, k, m. what has julian's average speed been so far?

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
