Step-by-step explanation:
The amount of strontium that will remain after 40 hours is 5 g
<h3>How to determine the number of half-lives </h3>
- Half-life (t½) = 10 hours
- Time (t) = 40 hours
- Number of half-lives (n) =?
n = t / t½
n = 40 / 10
n = 4
<h3>How to determine the amount remaining </h3>
- Original amount (N₀) = 80 g
- Number of half-lives (n) = 4
N = N₀ / 2ⁿ
N = 80 / 2⁴
N = 80 / 16
N = 5 g

Answer: The length of point A(-3,1) and B(2,6) is .
Step-by-step explanation:
We know that the distance between the two points (a,b) and (c,d) is given by :-
Given points = A(-3,1) and B(2,6)
Therefore the distance between the points A(-3,1) and B(2,6) is given by :-
Hence, the length of point A(-3,1) and B(2,6) is .
