South of the equator, in the midst of the Brazilian rain forest, sits the bustling coastal city of Rio de Janeiro. Known for its beautiful beaches
and tropical weather, Rio de Janeiro is a city that loves to celebrate.
Every February, Rio hosts Carnival, a huge, multiday festival that
involves floats, costumes, music, and dancing. But it's not just Carnival,
in 2014, Brazil hosted the World Cup soccer tournament, and Rio's
citizens are preparing to host the 2016 Olympics as well. With so much
going on, shouldn't you get busy booking your ticket to Rio?
Which is a subjective summary of the passage?

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
