Answer:
The equation is .
0.4713 grams would remain in the tumor after 8.5 days.
Step-by-step explanation:
Exponential equation of decay:
The exponential equation for the amount of a substance that decays, after t days, is given by:
In which A(0) is the initial amount and r is the decay rate, as a decimal.
A tumor is injected with 0.52 grams of Iodine-125.
This means that
After 1 day, the amount of Iodine-125 has decreased by 1.15%.
This means that
So
Then use the formula for A(t) to find the amount of Iodine-125 that would remain in the tumor after 8.5 days.
This is A(8.5).
0.4713 grams would remain in the tumor after 8.5 days.
Pretty fast consider 115ft wasn't enough to avoid an accident..
Answer:
1005
Step-by-step explanation:
If you just kept subtracting from 2580 then the next and then the next number you would get 1005
Answer:
=
Step-by-step explanation:
=, because 0 x 4 equals 0, and 0 x 9 equals 0. And 0 = 0. Hope this helped!
