1188 = π<em>r</em>²<em>h</em>

For the formula to solve for <em>h, </em>you have to change the equation to:

<em>h </em>= 1188/π<em>r</em>²

which is just moving h to the left side of the equation, and moving v(in this case 1188) to the right side.

because <em>h </em>was multiplied to the original equation, switching sides in an equation makes its replacement(1188) into a devision. (if you move a number across the = sign, the number will become the opposite of itself.)

Since you don't know the radius, you can't simplify this equation.

The answer is <em>h </em>= 1188/π<em>r</em>²

Solve n^2+16n=17 by completing the square ​
larisa [96]

Answer:

305 or N=1

Step-by-step explanation:

N=17, correct?

so what you do first is rewrite the equation:

17^2+16

which will equal:

305

if not and the equation is N^2+16=17

then you have to subtract the 16 first from 17

n^2=1

now you divide or whatever you call it XD

/n^2=/1

so the answer to N=1

Which is the equation of the parabola with focus (6, 2) and vertex (6, –4)?
SVETLANKA909090 [29]

Based on the calculations, the equation of this parabola is equal to (x - 6)² = 16(y + 4).

<h3>How to determine the equation of this parabola?</h3>

Mathematically, the standard equation with the vertex for a parabola is given by:

(y - k)² = 4a(x - h) for horizontal parabola.

(x - h)² = 4a(y - k) for vertical parabola.

<u>where:</u>

  • h and k are the vertex.
  • a is a point.

By critically observing the points, we can deduce that both the focus and vertex lie on the same vertical line x = 6.

<u>Given the following data:</u>

Focus with points = (6, 2).

Vertex (h, k) = (6, –4).

<u>Note:</u> a = 2 - (-4) = 2 + 4 = 6.

Substituting the given parameters into the formula, we have;

(x - 6)² = 4 × 4(y - (-4))

(x - 6)² = 16(y + 4).
