Answer:
14,146 years
Step-by-step explanation:
The annual multiplier is (1 -0.0049%) = 0.999951. We want to find the number of times this needs to be multiplied to make the product 1/2.
0.5 = 0.999951^t
log(0.5) = t·log(0.999951)
log(0.5)/log(0.999951) = t ≈ 14,145.514
The half-life is about 14,146 years.

Reflection about the y-axis involves flipping the sign of the x-value.
Therefore:
(2,3) -> (-2,3)
(-4,-5) -> (4,-5)
(-2,4) -> (2,4)
The new coordinates are (-2,3), (4,-5), and <span>(2,4)</span>
