Answer:
<h3> -3 * r

</h3>
Step-by-step explanation:
at least means it can be 57 or higher
Sin = opposite / hypotenuse
cos = adjacent / hypotenuse
using pythagoras theorem =
adjacent = 5^2-3^2
= 16
= square root 16
=4
cos x = 4/5
The work is equal to the line integral of
over each line segment.
Parameterize the paths
- from (0, 0, 0) to (2, 0, 0) by
with
, - from (2, 0, 0) to (2, 4, 1) by
with
, - from (2, 4, 1) to (0, 4, 1) by
with
, and - from (0, 4, 1) to (0, 0, 0) by
with 
The work done by
over each segment (call them
) is




Then the total work done by
over the particle's path is 46.
Answer:
from side a _2,4.5
from side b _-4
5,-2.
