Ascientist begins an experiment with a culture of 5 bacteria cells. every hour, the number of bacteria cells triples. which equation can be used to represent the number of bacteria cells, y, as it relates to time in hours, x?
a. y = 5 x
b. y = 3(5) x
c. y = 3 x
d. y = 5(3) x

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
