Henrietta did an experiment. She started out with 800 bacteria cells. She found that the growth rate of the bacteria cells was 3.2%. Sketch the graph that represents the situation. Label the y-intercept and the point that represents the projected bacteria population 35 h from the time Henrietta started the experiment. I need help asap please
Answer:
See belowStep-by-step explanation:
Given
Initial number of bacteria = 800Growth rate = 3.2% = 1.032 timesRequired equation:
B(t) = 800(1.032)^t, where B- number of bacteria, t- time in hoursThe y-intercept is:
B(0) = 800*1.032^0 = 800The point (0, 800)Bacteria population 35 in hours:
B(35) = 800*1.032^35 = 2409The point (35, 2409)Describe all the x-values at a distance of 20 or less from the number 12. Enter your answer in interval notation.
