You place a cup of 200 degrees f coffee on a table in a room that is 67 degrees f, and 10 minutes later, it is 195 degrees f. approximately how long will it be before the coffee is 180 degrees f? use newton's law of cooling: t(t)=t[a]+(t[o]-t[a])e^-kt a. 40 minutes b. 15 minutes c. 1 hour d. 35 minutes

To find the extreme values of a function f(x. y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x, y)=xy
