An entomologist discovered a new insect species. The population of the insect species can be modeled by P(n)=3,450 • b^n, where n is the number of days and b is the unknown positive base. Based on the model, there were initially ___ insects.

If b=1.75, the daily percent growth rate of the new insect would be ___%

If there are 55,200 new insects after 4 days, then b= __

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

the correct option is b

step-by-step explanation:

i believe a. 12x≥120 is the answer
