(C) (-2, -36) . . . . . . is the appropriate choice
_____
An easy way to tell is to let a graphing calculator show you.
Or, you can rearrange the equation to vertex form.
f(x) = 5(x² +4x) -16
= 5(x² +4x +4) -16 -5*4 . . . . complete the square
= 5(x +2)² -36
So, the vertex is (-2, -36).

<h3>Answer:</h3>
4 m
<h3>Explanation:</h3>
If we let h represent the height of the sail, then its width is h/2. The area of the sail is given by ...
... A = (1/2)wh
Filling in the given information, we have
... 4 m² = (1/2)(h/2)h
... 16 m² = h² . . . . . . multiply by 4
... 4 m = h . . . . . . . . take the square root
Answer:
false
