Y=-5x+1
Slope intercept form is y=mx+b
m is slope and b is the y-intercept
Answer:
This is a typical radioactive decay problem which uses the general form:
A = A0e^(-kt)
So, in the given equation, A0 = 192 and k = 0.015. We are to find the amount of substance left after t = 55 years. That would be represented by A. The solution is as follows:
A = 192e^(-0.015*55)
A = 84 mg
F + R = 2.75
2.125 + R = 2.75
R = 2.75 - 2.125
R = .625
Hope this helps :)
The answer is 10.6 units .....
