A petri dish originally contained 140 bacteria. A scientist let the bacteria grow and now there are 870 of them. How many more bacteria are there now?

A scientist observes a population of bacteria in a petri dish. The population grows exponentially, doubling every 2hours. After 4hours of observation, there are about 6,000 bacteria.Which equation can you use to estimate n, the number of bacteria that were originally in the petri dish?

The number of bacteria in a petri dish on the first day was 252252 cells. If the number of bacteria increase at a rate of 57%57% per day, how many bacteria cells will there be after 77 days?

Instructions: Create the equation of the form y=a(b)x for the exponential function described in each real-world problem. Then, use the equation to answer the question.The number of bacteria in a petri dish on the first day was 113113 cells. If the number of bacteria increase at a rate of 82%82% per day, how many bacteria cells will there be after 77 days?y=𝑦= Answer 1 Question 16 (( Answer 2 Question 16 )x)𝑥What number will you fill in for x𝑥 to solve the equation? Answer 3 Question 16y=𝑦= Answer 4 Question 16

Bacteria are growing in a culture, and their number is increasing at the rate of 6% per hour. Initially, 200 bacteria are present.Determine an equation that gives the number

A student performed a spread plate count of a bacterial culture and recorded 32 and 48 colonies on duplicate plates of the 10-4 dilution. What will be the bacterial count (cfu/ml) in the original culture?
