The circumference of a pizza is 56.52 in. One-fourth of the pizza has been eaten the area of the remaining pizza in sq. Inches r
BabaBlast [244]
Circumference = πD
πD = 56.52
D = 17.99 in

Area of the pizza = π (17.99 ÷ 2)²  = 254.19 in²

Area of the pizza eaten = 254.19 ÷ 4 = 63.55 in²

Area of the pizza remain = 254.19 - 63.55 = 190.64 in²

Answer: 190.64 in²

Write f(x) = 2x2 – 44x 185 in vertex form. To write f(x) = 2x2 – 44x 185, factor out from the first two terms. Next, form a perf
Tasya [4]

The quadratic function f(x) = 2x² – 44x + 185 is written in vertex form is f(x) = 2(x –  11)² – 57.

<h3>What is a quadratic equation?</h3>

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

The quadrattic equation is f(x) = 2x² – 44x + 185.

Take common 2 from the equation, we have

f(x) = 2(x^2 - 22x )+ 185

Add and subtract 121, we have

f(x) = 2(x^2 - 22x +121 - 121 )+ 185\\\\f(x) = 2[(x^2 - 11)^2-121]+ 185\\\\f(x) = 2(x-11)^2 - 242 + 185\\\\f (x ) = 2(x-11)^2 -57

And we know that the standard equation

f(x) = a(x - h)² + k

On comparing, we have

The vertex (h, k) is (11, -57).

More about the quadratic equation link is given below.
