Aradioactive substance decays exponentially. a scientist begins (t=0) with 200 milligrams of a radioactive substance, where the variable t t represents time (in hours). after 24 hours, 100 mg of the substance remain. how many milligrams will remain at t= 37 hours?

34.35 mg.

Step-by-step explanation:

We have been given that a radioactive substance decays exponentially. A scientist begins (t=0) with 200 milligrams of a radioactive substance, where the variable t represents time (in hours). After 24 hours, 100 mg of the substance remain.

We know that an exponential decay function is in form , where,

A(t) = Final amount,

a = Initial value,

b = Decay rate,

t = time.

For our problem initial value (a) is 200, final amount is 100 and time is 24.

Let us solve for b.

So our required function is .

Substitute in above equation:

Therefore, 34.35 milligrams of substance will remain after 37 hours.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
