Problem: Find the half-life, in days, of 1-131 using the
information at the left. Round your answer to
the nearest tenth
A medical scintist has a 15 gram sample
of 1.131 and would like to its half-life, in
days. He also knows that k - 0.0856.
N= Noek
No - 15 grams
Enter the correct answer
DONE
N-7.5 grams
k0.0856
t?

so then what are you asking?

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
