The value of the function at x = 5, will be 343. Then the correct option is A.
<h3>What is an arithmetic sequence?</h3>Let a₁ be the first term and r be the common ratio.
Then the nth term of the geometric sequence is given as,
aₙ = a₁ · (r)ⁿ⁻¹
We know that the first term is 1/7 and the common ratio is 7.
Then the equation will be
Then the value of the function at x = 5, will be
y = (1/7) · (7)⁵⁻¹
y = (1/7) · (7)⁴
y = 7³
y = 343
Thus, the value of the function at x = 5, will be 343.
Then the correct option is A.

6.665 grams of the 13 grams remain after 8 hours.
<h3>How much of a 13 gram sample of iron-52 would remain after 8 hours?</h3>The decay equation for the 13 grams of iron-52 is:
Where N is the amount of iron-52, and t is the time in years.
Where we used the fact that the half-life is exactly 8.3 hours.
Now, the amount that is left is given by N(8h), so we just need to replace the variable t by by 8 hours, so we get:
So 6.665 grams of the 13 grams remain after 8 hours.
