In a lab, 750 cells are present at the beginning of an experiment. During the first 7 hours, the number of cells increased by 16% each hour. Write an exponential mode giving the number of cells y present t hours after starting the experiment. Estimate the time when the number of cells is 2460.

step-by-step explanation:

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
