Answer:
y = -2
Step-by-step explanation:
See the attached image in the attachment. When x is zero, it intersects the y-axis at y = -2
If we substitute and , we get , so that
which is independent of , which in turn means the surface can be treated like a surface of revolution.
Consider the function defined over . Revolve the curve described by about the line . The area of the surface obtained in this way is then
25 doughnuts
for 15 workers,
the numbers of doughnuts =
5 doughnuts/3 workers × 15 workers
= 75/3 doughnuts
= 25 doughnuts
