The starting weight of the radioactive isotope = 96 grams
Weight after one hour is half of the starting weight. So the weight of the radioactive isotope after 1 hour = 48 grams
After 2 hours the weight is half as compared to the weight after previous hour. So weight after 2 hours = 24 grams.
This means, after every hour the weight is being halved. The half life of radioactive isotope is one hour.
Since after every hour, the weight is being halved, the weight of the isotope can be modeled by an exponential equation.
So,
Initial Weight = W₁ = 96
Change factor = 1/2 = 0.5
The general equation of the sequence will be:

Here t represents the number of hours. Using various values of t we can find the weight of the radioactive isotope at that time.
We can plot the sequence using the above equation. The graph is attached below.
Answer:
Do using Pythagoras theorem... Also before doing a question of height and distance always try to make the figure
Step-by-step explanation:
Use the two triangles ABC and ABD to first get the base and find the height of the ladder
Hey there! We are given two decimal numbers to compare.
52.311 and 52.31
These two numbers are similar except that 52.311 has another 1 in while 51.31 doesn't.
Keep in mind that 52.31 can also refer to 52.310
So we are comparing 52.311 and 52.310
Since 1 is greater than 0.
52.311 is greater than 52.31 (52.311 > 52.31)
Let me know if you have any questions!
