Answer:
The equation of the line passing through the points (-2,0) and (0,-4)
The equation of the line passing through the points (0,-2) and (4,0)
Option B
x minus 2 y = 4 and 2 x + y = negative 4
(x-4)(x^2+3x+5)
=(x^3+3x^2+5x-4x^2-12x-20)
=(x^3-x^2-7x-20)
Hope this helps!
Answer:
With the initial amount and t the time on hours and t the time in hours. since the half life is 12 hours we can find the parameter of decay like this:
And solving for b we got:
And then we have:
And the model would be given by:
Step-by-step explanation:
Assuming this complete question: "A specific radioactive substance follows a continuous exponential decay model. It has a half-life of 12 hours. At the start of the experiment, 82.6g is present.
"
For this case we can create a model like this one:
With the initial amount and t the time on hours and t the time in hours. since the half life is 12 hours we can find the parameter of decay like this:
And solving for b we got:
And then we have:
And the model would be given by:
X >_(-5)
The third option from the left.
