1. Three trains A, B, and C, leave the train station at the same time. The graph below shows the relationship between time and distance for Train A. Based on the graph below, what is the speed of Train A expressed in unit rates?
A' 40 miles per hour
B' 30 miles per hour
C' 120 miles per 4 hours
D' 180 miles per 6 hours
Graph for Train A
2. The relationship between time and distance for Train B is given by equation d=45t, where d represents distance in miles and t represents time in hours. Based on the equation d=45t, what is the speed of the train?
A' t, that is time in hours
B' 45 miles per hour
C' d, that is distance in miles
D' not enough information

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
