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.

We have
First, we can combine like terms 3y and -7y to get -4y.
Then, we have
We could then subtract 8 on both sides to get
Finally, we isolate y completely by dividing both sides by -4, to get
Answer:
The third approximation is
Step-by-step explanation:
We are given that
We have to find the second and third approximation of a root of given equation by using Newton's method.
We know that Newton's method , if nth approximation is given and then, the next approximation is given by
Substitute
Substitute the value n=1 then, we get
Substitute the values then , we get the second approximation
For n=2
Hence, the third approximation is
You would write the number patter like 8*5
