Consider a colony of e. coli bacteria that is growing exponentially. a microbiologist finds that, initially, 1,000 bacteria are present and 50 minutes later there are 10,000 bacteria. a) find expression for the number of bacteria q(t) after t minutes. b) when will there be 1,000,000 bacteria?

a)

b) 150min

Step-by-step explanation:

a) Using the formula for colony growth we need to find the specific value of k, to do this you'll use the time, initial and final number of colonies provided in your problem.

b) Once we have our expression we only have to use our final and initial number of bacteria to find t.

I hope you find this information useful! good luck!

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
