What is the mass of a train traveling at an
acceleration of 40 m/s2 with a force of 360 N?

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:    

The criminological theory that alan used to address the problem is routine activity theory.  in this situation, the community was not supported by the political party. as a result, alan was forced to resort to crime because of the status that his family is currently in. 

What exactly are you asking? i’d love to , explain, what you are asking : )
