Complete the square
(h,k) is the vertex
so
f(x)=2x²-12x+16
group x terms
f(x)=(2x²-12x)+16
factor out the 2
f(x)=2(x²-6x)+16
take 1/2 of the linear coefient and square it
-6/2=-3, (-3)²=9
add positive and negative insides parnthases
f(x)=2(x²-6x+9-9)+16
factor perfect square
f(x)=2((x-3)²-9)+16
distribute
f(x)=2(x-3)²-18+16
f(x)=2(x-3)²-2
h=3
k=-2
vertex is (3,-2)
vertex form is f(x)=2(x-3)²-2
The answer is 42 becuase you are making 53 groups of 2226 you can also simply solve it by useing long division

Perpendicular Lines meet at a 90° angle.
The surface area of Spaceship Earth is: 7850 m^2
Step-by-step explanation:
Given
Diameter of spherical structure = d = 50 meters
As the attraction is in the form of a sphere, its radius will be used to find the surface area.

The formula for surface area of sphere is:
