Under favorable conditions bacteria can multiply every 20 minutes. starting with one bacterial cell, how many bacteria should you expect after 15 hours? hint: under favorable conditions, if one bacterium becomes 2 in 20 minutes(1 multiplied by 2), those 2 become 4 in the next 20 minutes, and then those 4 become 8 in the next 20 minutes. that means that 8 bacteria resulted in 1 hour. now calculate the growth of bacteria for 15 hours.

Answer: fn = wcos50 = 38.89(9.81)(cos50) = 245.23 n

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
