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. Five hours later, he measures 400 bacteria. Assuming
exponential growth, what is the growth rate for the bacteria?

Give me the equations of two lines that have the same slope but are not parallel.

What’s the answer ? use the picture to see the problem

Ariana starts with 100 milligrams of a radioactive substance. the amount of the substance decreases by 20% each week for a number of weeks, w. the expression 100(1−0.2)w finds the amount of radioactive substance remaining after w weeks. which statement about this expression is true? a) it is the difference between the initial amount and the percent decrease. b) it is the difference between the initial amount and the decay factor after w weeks. c) it is the initial amount raised to the decay factor after w weeks. d) it is the product of the initial amount and the decay factor after w weeks.
