3 poi 7. The number of cells in a petri dish grows exponential with time. The function h models the number of cells present after t hours. Based on the function, which statement is NOT true? h(t) = 50(2): There were 50 cells initially in the petri dish. O The predicted number of cells doubles every 15 minutes. O Approximately 400 cells will be in the petri dish after 12 hours The predicted number of cells doubles every 4 hours.
A culture of bacteria in a petri dish is doubling every hour. If there are 100 bacteria at time t=0, how many bacteria will there be in 12 hours?
in an experiment with a cell line, 30% of the cells in a petri dish divide into two every hour and 10% of the cells die every hour. The remaining 60% of the cell survive without dividing. Let y_n be the number of cells in the petri dish after n hours. Suppose that y0=100. Determine the correct recursive formula for y_n (for all n>0) and use it to compute the value of y2

The population of a certain type of bacteria, kept in a Petri dish at a constant 25 C,changes according to the Limited Growth Model. An initial population of 10 million bacteria increases to 15 million carrying capacity, M, of this system is 40 million bacteria. (Recall: for this model the rate of population with respect to time,...
PLEASE HELP!! Clear steps for each part would be much
appreciated. thank you!
It's not just money that multiplies with time... Suppose the number of bacteria on the surface of a phone screen doubles every 3 hours. 4. Write a function for the population, p, of bacteria as a function of n where n is the number of 3-hour periods since the bacteria first start multiplying. Call the initial population po a. b.
