<u>Algebra II</u>

  • Exponential Rule [Powering]: \displaystyle (b^m)^n = b^{m \cdot n}
  • Solving exponential equations

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em />\displaystyle 3^{6x + 18} < 27^{3x}<em />

<em />

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Rewrite:                                                                                                             \displaystyle 3^{6x + 18} < 3^{3(3x)}
  2. Set:                                                                                                                     \displaystyle 6x + 18 < 3(3x)
  3. Factor:                                                                                                               \displaystyle 3(2x + 6) < 3(3x)
  4. [Division Property of Equality] Divide 3 on both sides:                                  \displaystyle 2x + 6 < 3x
  5. [Subtraction Property of Equality] Subtract 3x on both sides:                       \displaystyle -x + 6 < 0
  6. [Subtraction Property of Equality] Subtract 6 on both sides:                        \displaystyle -x < -6
  7. [Division Property of Equality] Divide -1 on both sides:                                 \displaystyle x > 6

Find the standard form of the equation of the parabola with a focus at (0, 2) and a directrix at y = -2.
LUCKY_DIMON [66]

Since the focus is at (0, 2) and directrix is y = -2

point where both of these have the same x-value will be at (0, 2) for the focus and (0, -2) for the directrix.

The vertex will also have the same x-value so it will be (0, y).

y-value is half-way between the y-value of the focus, and the y-value of the directrix at x = 0.

Directrix y-value is -2 at x = 0 and for the focus it's 2 at x = 0. 

Halfway between y = -2 and y = 2 is y = 0. 

So the vertex of the parabola occurs at (0, 0). 

So that's x^2 = 4ay = 4(2)y = 8y. 

y = 1/8*x^2

hope it helps
