Which graph represents y=3√x+2
1 answer:
Adding 2 outside of the third root of x, , will shift the regular y=third root of x graph up 2 units.
Answer: #3
Now if the "+2" is inside the third root, , then this will shift the graph left 2 units and the answer would be #2.
It's unclear from the picture if the "+2" is inside or outside the radical.

<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.
