The amount of radioactive material remaining after 24 hours is 92.15 kg.
<h3>Exponential function</h3>An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the amount of the substance after t hours.
From the equation, a = 100 mg
Also, after 6 hours:
After 24 hours:
y = 100(0.9966)²⁴ = 92.15 kg
The amount of radioactive material remaining after 24 hours is 92.15 kg.

We know that,
Interest, I =
Where, P = Principal = $1300
R = rate of interest = 9% annually =
%
T = Time = 1 month
So, I =![\frac{1300×[tex] \frac{9}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1300%C3%97%5Btex%5D%20%5Cfrac%7B9%7D%7B12%7D%20)
×1}{100} [/tex]
= $9.75
Interest paid per month is $9.75
