Answer:
384.3
Step-by-step explanation:
The mass of radioactive material remaining after 50 years would be 48.79 kilograms
<h3>How to determine the amount</h3>
It is important to note that half - life is the time it takes for the amount of a substance to reduce by half its original size.
Given the radioactive decay formula as
m(t)=120e−0.018t
Where
t= 50 years
m(t) is the remaining amount
Substitute the value of t
Find the exponential value
m(t) = 48.788399
m(t) = 48.79 kilograms to 2 decimal places
Thus, the mass of radioactive material remaining after 50 years would be 48.79 kilograms

Lentgh * width = area so, 3.5*9 right?
I think this is the associative property of multiplication.
Answer:
232
Step-by-step explanation:
all u gotta do here is plug in 40 here so:
0.145(40)x^2
0.145(1600)
f(x)= 232
