Answer:
ok
Step-by-step explanation:
The line y=1 is the horizontal line passing through the point (0, 1). We have drawn it with red.
The reflection across this line of each point X, Y, and Z is such that the distance of each X, Y, and Z is equal to the distance of each X', Y', and Z', respectively, to the red line.
According to our drawing, we see that the coordinates of X' are (3, 3).
Answer: a.
It will be 3:45. You can find this by going ahead 3 hours, then going ahead a half an hour.
I'll go ahead and assume you meant to say that <em>S</em> is the surface given by

This immediately gives us a parameterization for the surface,

The upward-pointing normal vector to this surface is then

Then the flux of
across <em>S</em> is

Answer:
3.) a. 9mm b. 10mm c. 8mm
Step-by-step explanation:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.
Formula:
a + b = (answer) > c
a + c = (answer) > b
b + c = (answer) > a
try to solve it yourself so you can do it on your own in the future.
