This part of the plane is a triangle. Call it
. We can find the intercepts by setting two variables to 0 simultaneously; we'd find, for instance, that
means
, so that (4, 0, 0) is one vertex of the triangle. Similarly, we'd find that (0, 5, 0) and (0, 0, 20) are the other two vertices.
Next, we can parameterize the surface by
so that the surface element is
Then the area of
is given by the surface integral
Answer:
300 doors.
Step-by-step explanation:
1.5 minutes for 1 door.
7.5 hours for 300 doors.
7.5 hours = 450 minutes.
Answer:
D'(1,5)
Step-by-step explanation:
If you rotate a point 180 counter-clockwise around the origin, then it makes the x and y coordinates negative. In this case, it would make the coordinates positive because both coordinates are already negative. The answer would be D'(1,5).
