The half-life of the given exponential function is of 346.57 years.
<h3>What is the half-life of an exponential function?</h3>
It is the value of t when A(t) = 0.5A(0).
In this problem, the equation is:
.
In which t is measured in years.
Hence the half-life is found as follows:





t = 346.57 years.

#SPJ1
A = 9/10
b = 1/3
c = 2/3
I dunno how to explain it properly but the question gives the fractions, you just need to find out what makes the other fraction that can equal to 10/10 for the first part, then 3/3 for the second part.
Multiply 3 by 2 then multiply the product by 10= 60 minutes or 1 hour
Answer:
5/1
Step-by-step explanation:
The reciprocal is just flipping the fraction!
