Answer:
The answer to your question is: y = 8x
Step-by-step explanation:
As both lines are parallels, then the slope is the same.
From the line given, get the slope
m = 8
Point (0, 0)
(y - y1) = m(x - x1)
(y - 0) = 8(x - 0)
y = 8x
About 92 days are taken for 90 % of the material to <em>decay</em>.
The mass of radioisotopes (), measured in milligrams, decreases exponentially in time (
), measured in days. The model that represents such decrease is described below:
(1)
Where:
- Initial mass, in milligrams.
- Current mass, in milligrams.
- Time constant, in days.
In addition, the time constant is defined in terms of half-life (), in days:
(2)
If we know that ,
and
, then the time required for decaying is:
About 92 days are taken for 90 % of the material to <em>decay</em>.
