Given matrices g and h below, which statement is true?

g= 7 5
4 3

h= -6 -5
-4 -2

a.) matrices g and h are not inverses of each other because g + h does not equal i.

b.) matrices g and h are not inverses of each other because gh does not equal i.

c.) matrices g and h are inverses of each other because gh = i.

e.) matrices g and h are inverses of each other because g + h = i.

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.
