Answer:
Step-by-step explanation:
The first rotation is clockwise, whereas the second is counterclockwise. We end up at the same point either way, and the trig functions are the same.
In summary, the final outcomes are the same, but the directions of rotation are different. For this reason: False

Answer:
3.2
Step-by-step explanation:
x² + xy = 20
Take the derivative with respect to time:
2x dx/dt + x dy/dt + y dx/dt = 20
(2x + y) dx/dt + x dy/dt = 20
Given x = -5, y = 1, and dx/dt = -4:
(2(-5) + 1) (-4) + (-5) dy/dt = 20
(-10 + 1) (-4) − 5 dy/dt = 20
36 − 5 dy/dt = 20
5 dy/dt = 16
dy/dt = 3.2
