Answer:
y - value of the vertex is 49.
Step-by-step explanation:
Given function is f(x) = -(x - 3)(x + 11)
f(x) = -(x² - 3x + 11x - 33)
= -(x² + 8x - 33)
= -(x² + 8x + 16 - 49)
= -[(x + 4)² - 49]
= -(x + 4)² + 49
Comparing this equation with the vertex form of a quadratic function,
f(x) = -(x - h)² + k
Where (h, k) is the vertex of the function.
Vertex of the parabola is (-4, 49)
Therefore, y-value of the vertex is 49.

Answer:
thank you
Step-by-step explanation:
Perimeter of a square=4*side length
160=4*side length
40=side length
Therefore, 39.99999 (repeating 9s) is the maximum side length in feet for the perimeter to be less than 160. If it was 40 feet as the side length, then it would not be less than 160.
Hope this helps!
