a particular strain of bacteria doubles in population every 10 minutes. Assuming you start with a single bacterium in a petri dish, how many bacteria will there be in 2.5 hours? A. 16,384 B. 65,536 C. 32,768 D. 9536

32768

Step-by-step explanation:

The formula for exponential growth is

y = a b^x  where a is the initial value and b is the growth rate and x is the number of times

a = 1

b = 2 since we are doubling

To find x we take the amount of time we have 2.5 hours = 2.5 *60 = 150 minutes  divided by the 10 minute doubling time

150/10 = 15 times

y = 1 * 2^ 15

y =32768

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
