<span>A logical truth is a statement which is true, and remains true under all reinterpretations of its components other than its logical constants. It's a type of analytic statement.</span>
Step-by-step explanation:
The particle is at rest when the derivative of x(t), which is its velocity, is zero, i.e.,
![\dfrac{d}{dt}[x(t)] = \dot{x}(t) = 0](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7Bdt%7D%5Bx%28t%29%5D%20%3D%20%5Cdot%7Bx%7D%28t%29%20%3D%200)
Since
its derivative is

Equating this to zero, we get

This is a familiar quadratic equation whose roots are




This means that the particle will be at rest at t = 3 and t= 4.
There can only be less than or equal to 125 customers, you can't have more than that but you can have exactly 125 or less than 125. your inequality should look like < 125 with a line underneath the symbol to describe "equal to"
