Step-by-step explanation:
All radioactive isotopes decay exponentially, the mass of the isotope as a function of time (
), measured in grams, is defined by:
(1)
Where:
- Initial mass of the isotope, measured in grams.
- Decay rate, measured in 
or 
or 
.
- Time, measured in minutes, days or years.
We define the decay rate in terms of half-life by using the following expression:
(2)
Where 
is the half-life of the isotope, measured in minutes or years.
Now we proceed to determine the missing values:
a) Polonium-200 (
)
b) Lead-194 (
)
c) Iodine-125 (
)
d) Kryption-75 (
)
e) Strontium-79 (
)
f) Uranium-229 (
)
g) Plutonium-239 (
)
Answer:
900000000
Step-by-step explanation:
Area=400×500
=60000m²
Since
1m² = 15000
60000m² = x
x = 60000×15000
x = 900000000
Answer:
212 feet
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Base and height so you would multiply 1/2 with 4 then divide by two and you get your answer
