veryical velocity is 88sin35° = 50.47 ft/s So, y = 50.47t - 16t^2 set y=0 and solve for t.
what, no calculator?
xy=384 so, y = 384/x f = 2x+3y = 2x + 1152/x df/dx = 2 - 1152/x^2 min f is when df/dx=0, at x=24 So, the field is 24x16 f = 48+48=96 as usual in these problems, the fencing is divided equally among lengths and widths.
in x years since 1985, the salary is s(x) = 8000+600x so, plug in x = 2012-1985
this just a parabola, with vertex at t = -2vo/-9.8
just looking at the units involved, I'd say .13J/g°C * 25.0g * (1063-23)°C = 3380J
math - eh?
You talk about two functions, yet ask about "its" equation. Better clarify just what it is you want.
this is just the kind of question that does not get much help here. Any web search will provide lots of discourses on the topic. No doubt your text does, as well. So, a long essay here will probably not shed any more light on your confusion. Do you have a particular question t...
is something wrong with the analysis I gave at http://www.jiskha.com/display.cgi?id=1385542021 ?
