Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
