Compare and contrast interpolations and extrapolations based on a scatterplot

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.

What is the value of g(8) for the function g(x) in part c? what does this value mean in the context of the situation you described in part c?

If sina is 4/5 then find the value of sin3a . with explanation.
