Question

The decay of a radioactive substance is given byA = 200(1/2) t/10. Which answer is an equivalent equationfor the decay that shows the approximate amount of/decayin 4 years?

Answer 1

The decay of a radioactive substance is given by

A = 200(1/2) t/10.

The equivalent equation for the decay that shows the approximate amount of decay in 4 years

Hence the correct option that approximately amounts to decay in 4years is

`A=151.57(0.933)^(t-4)`

Option C is the correct answer cause it matches the red image
