Answer:

see explanation

Step-by-step explanation:

given a parabola in standard form : y = ax² + bx + c : a ≠ 0

Then the x- coordinate of the vertex which is also the axis of symmetry is

x_{vertex} = - \frac{b}{2a}

y = 3x² - 24x + 38 is in standard form

with a = 3, b = - 24 and c = 38, hence

x_{vertex} = - \frac{-24}{6} = 4

Substitute x = 4 into the equation for corresponding y- coordinate

y = 3(4)² - 24(4) + 38 = 48 - 96 + 38 = - 10

vertex = (4, - 10)

equation of axis of symmetry is x = 4

dexar [7]

Answer:

the norm of V = =11.357816691601..

Step-by-step explanation:

\left\vert \overrightarrow{V} \right\vert  =\sqrt{\left( -8\right)^{2}  +\left( 7\right)^{2}  +\left( 4\right)^{2}  }

      =\sqrt{64+49+16}

      =\sqrt{129}

      =11.357816691601...
