Akira is folding a piece of paper that is 0.2 millimeters thick in half. The thickness of the paper doubles with each fold.
Let n represent the fold number and t (n) represent the thickness of the paper.
Which exponential function represents this scenario?
A t(n) = 1/2 (0.2)"
B
t(n) = 0.2(2)”
с
t(n) = 0.2()"
D
t(n) = 2(0.2)”
( the " are n)
