Answer:
Per hour decay of the isotope is 0.96%.
Step-by-step explanation:
Amount of radioactive element remaining after t hours is represented by
where a = initial amount
t = duration of decay (in hours)
Amount remaining after 1 hour will be,
y = 0.9904a
So amount of decay in one hour = a - 0.9904a
= 0.0096a gms
Percentage decay every hour =
=
= 0.958 %
≈ 0.96 %
Therefore, per hour decay of the radioactive isotope is 0.96%.
Answer:
The slope of the equation is -3.
Step-by-step explanation:
Given : Mr. Mole's burrow lies 5 meters below the ground. He started digging his way deeper into the ground, descending 3 meters each minute.
To find : What is the slope ?
Solution :
Let x be the number of minutes taken to dig the ground.
He started digging his way deeper into the ground, descending 3 meters each minute i.e. '-3x'
Let y is the total distance travel to dig the ground.
Mr. Mole's burrow lies 5 meters below the ground.
The equation form is
Comparing with general slope form i.e. where m is the slope.
The slope of the equation is -3.
