Answer:

C

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (- 1, 9)

d = \sqrt{(-1-2)^2+(9-8)^2} = \sqrt{(-3)^2+1^2} = \sqrt{9+1} = \sqrt{10} → C

Answer:

\sqrt{10}

Step-by-step explanation:

Using the distance formula:

\sqrt{(x_b - x_a)^2 + (y_a - y_b)^2}

Plugging the numbers in:

\sqrt{(-1-2)^2 + (9 - 8)^2 }

Simplify:

\sqrt{9 + 1}

Answer:

\sqrt{10}

Find the focus and directrix of the parabola with the equation x² = -22y.
Bad White [126]

9514 1404 393

Answer:

  focus: (0, -5.5)

  directrix: y = 5.5

Step-by-step explanation:

The equation compares to the form ...

  x² = 4py

where 4p = -22   ⇒   p = -22/4 = -5.5.

The value of p is the distance from the vertex to the focus. The negative value means the focus is below the vertex at (0, -5.5).

The directrix is above the vertex by the same amount, so is y = 5.5.
