Rearranging x=x0e^-lambda t in the form y=mx+c

AI Thread Summary
To rearrange the equation x = x0e^(-lambda t) into the form y = mx + c, take the natural logarithm of both sides, resulting in ln x = -lambda t + ln x0. In this rearrangement, -lambda serves as the gradient (m), while ln x0 represents the y-intercept (c). The discussion clarifies that h0 was a typographical error and should refer to x0. This transformation effectively linearizes the exponential decay function. Understanding these relationships is crucial for analyzing exponential models in various applications.

Hi, How could I rearrange x=x0e^-lambda t into the form y=mx+c, where y is equal to ln x and x is equal to t?

Thank you in advance

I tried to solve the problem myself, by taking the natural log of both sides, this left me with:

ln x = -lambda t * lnx0

However, I am not sure if this answer is correct or not

If this is correct, would -lambda represent the gradient? And, would ln x0 represent the y intercept

What is h0?
The logarithm of a product is the sum of logarithms, so you should get ##-\lambda t + \ln(x_0)##.

Sure.

My mistake h0 was supposed to represent x0
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
