1. (10 Points.) Consider the curve (in the plane) formed by: the line segment from (2, 0) to (5,0), the part of the circle of radius 5 (about the origin) from (5, 0) to (0, 5), the line segment from (0, 5) to (0, 4), and the part of the parabola y = 4 - x² from (0, 4) to (2, 0). Orient this curve so that the direction of travel on the first line segment is from (2, 0) to (5, 0). Let f(x, y) = ln √√x² + y². Calculate the flux of Vf across this curve (with the given orientation).

could you write this on paper so its easier to understand?

Let's say the countdown for a space shuttle launch has begun. At "T minus 25 hours" (that is, 25 hours before launch), a problem occurs. If the technicians have not fixed the problem by T minus 8 hours, the launch will have to be scratched. How much time (in hours) do the technicians have to correct the problem? hr
