a biologist is researching a newly-discovered species of bacteria. at time t = 0 hours, he puts 100 bacteria into what he has determined to be a favorable growth medium. six hours later, he measures 240 bacteria. assuming exponential growth, what is the equation to determine the number of bacteria after t hours?

a) y=100(240)^t

b) y=100(1.681)^t

c) y=100(2.4)^t

d) y=100(1.157^t

the correct answer would be A

Step-by-step explanation:

100 is the independent variable and 240 is the dependent variable think about is like interest rate

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

step-by-step explanation:

first, eliminate the parenthesis:
