The function f(x) = 30(1.4)x gives the number of bacteria in a science experiment, where x is the number of days after the start of the experiment. To the nearest whole number, how many bacteria will there be after 4 days?

115 bacteria

Step-by-step explanation:

The function that gives the number of bacteria in a science experiment is:

f(x) = 30(1.4)^x

Where x is the number of days

After 4 days (x = 4), the number of bacteria will be:

f(4) = 30 * (1.4)^4

f(4) = 39 * 3.8416

f(4) = 115.248 = 115 (To the nearest whole number)

The number of bacteria after 4 days is 115.

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )
