To find the length of the missing side, subtract all of the known side from the perimeter.
14 + 19 + 25 = 58.
73 - 58 = 15.
The fourth side is 15 feet
I hope that helps!
If (-1, -1) is an extremum of , then both partial derivatives vanish at this point.
Compute the gradients and evaluate them at the given point.
The first and third functions drop out.
The second function depends only on . Compute the second derivative and evaluate it at the critical point .
This indicates a minimum when . In fact, since this function is independent of , every point with this coordinate is a minimum. However,
for all , so (-1, 1) and all the other points are actually <em>global</em> minima.
For the fourth function, check the sign of the Hessian determinant at (-1, 1).
The second derivative with respect to is -2/(-1) = 2 > 0, so (-1, -1) is indeed a local minimum.
The correct choice is the fourth function.
Reflect A over the y axis. then rotate 90° counterclockwise. then translate 2 left.
Answer:
I think it would be 9 miles.
