<u>Answer:</u>
<em>Number of calories in one slice of a 14 inch pizza is 189.825. </em>
<u>Step-by-step explanation:</u>
Given that 6 inch pizza has <em>650 calories. </em>
Therefore 1 inch pizza has <em>calories.
</em>
14 inch pizza will have
Given that the 14 inch pizza is divided into 8 slices.
Therefore each slice of the 14 inch pizza will have

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
x coordinate =
= 2
y-coordinate = f(2)
= - (2)² + 4(2)
= -4 + 8
= 4
Therefore, vertex of the given function is (2, 4)
