Ascientist begins with 100 milligrams of a radioactive substance that decays exponentially. after 33 hours, 50 mg of the substance remains. how many milligrams will remain after 59 hours? (round your answer to two decimal places.)

Explanation:

Radioactive decay behaves according to the law of exponential decay:

Where:

So we need to find the decay rate r. Let's find it using the equation and the data provide, but first, we need to convert the hours in days:

Now for then:

Divide both sides by 100:

Take the natural logarithm of both sides:

Multiply both sides by -8/11:

Now we have found the rate decay r, let's find how many milligrams will remain after 59 hours (25/12 day):

it doesn't. it was imagined up in the middle ages.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
