Let y = 0, since the x-intercept occurs at y = 0.
We know this because the tangential graph is period every pi radians. The sinusoidal and co-sinusoidal graph are periodic every 2pi radians.
Answer:
t=19188.2 y
Step-by-step explanation:
The exponential decay equation is:
(1)
But, A is 10% of A₀, it means that A=0.10A₀.
If we put it into equation (1), we will have:
(2)
Now, we just need to solve (2) for t.
