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!

step-by-step explanation:

my butt

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
