The price of bronze has increased by 10% per year from 2000. in the year 2000, harry bought a bronze medal for $120. which of the following functions f(x) can be used to represent the price of the medal x years after 2000? f(x) = 120(0.9)x f(x) = 10(120)x f(x) = 120(1.1)x f(x) = 10(1.1)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.
