A parabola with vertex (h, k) and a vertical axis of symmetry is modeled by the equation y - k = a(x - h)2. Determine the vertex

Inessa05 [86]

<span>y - k = a(x - h)²

</span><span>y = (x − 5)² + 8 -------> y-8 = (x-5)²

</span>y - k = a(x - h)²
y - 8 = (x - 5)²
Compare these formulas we can see that k=8, h =5.

Vertex (5,8).

If e || f and a || b, what is the value of y. *

Blizzard [7]

Answer:

y = 90

Step-by-step explanation:

Since, e || f and a || b

Therefore, quadrilateral so formed is a rectangle.

Each angle of a rectangle is right angle.

$\therefore \: y \degree = 90 \degree \\ \\ \huge \red{ \boxed{ \therefore \: y = 90}} \\ \\$
