Answer:
36 pieces
Step-by-step explanation:
4 1/8 ft x 4 1/8 ft = 49.5 in x 49.5 in = 2450.25 in^2
8.25 in x 8.25 in = 68.06 in^2
2450.25/68.06 = 36 pieces
checking for scrap loss:
49.5/8.25 = 6
so no scrap loss
25%=.25
.25*750

Answer:
Vertex → (2, 4)
Step-by-step explanation:
Quadratic equation has been given as,
y = -x² + 4x
We rewrite this equation in the form of a function as,
f(x) = - x² + 4x
By comparing this equation with the standard quadratic equation,
y = ax² + bx + c
a = -1 and b = 4
Vertex of the parabola represented by this equation is given by ![[-\frac{b}{2a}, f(\frac{-b}{2a})]](https://tex.z-dn.net/?f=%5B-%5Cfrac%7Bb%7D%7B2a%7D%2C%20f%28%5Cfrac%7B-b%7D%7B2a%7D%29%5D)
x coordinate = 
= 2
y-coordinate = f(2)
= - (2)² + 4(2)
= -4 + 8
= 4
Therefore, vertex of the given function is (2, 4)
