Question

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)

Answer 1

• B. t(n) = 0.2(2)ⁿ

Explanation:

Initial value is 0.2 and increase rate is powers of 2 as it doubles with each fold.

Correct one is:

• t(n) = 0.2(2)ⁿ
