Write y=2x^2-12x+16 in vertex form

Step-by-step explanation:

The vertex is  

(

3

,

−

2

)

Explanation:

Given an equation of a parabola of the form:

y

=

a

x

2

+

b

x

+

c

The x-coordinate,  

h

, of the vertex, is:

h

=

−

b

2

a

The y-coordinate,  

k

, of the vertex, is:

k

=

a

h

2

−

b

h

+

c

From the given equation,  

y

=

2

x

2

−

12

x

+

16

, we observe that,  

a

=

2

,

b

=

−

12

and

c

=

16

Using the above formulas:

h

=

h

=

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
