$( {y - 8)}^{2} = - 28(x + 5)$

EXPLANATION

The given parabola has directrix x=2.

This implies that, the parabola is opens in the direction of the negative x-axis because it must open in a negative direction to the directrix.

The equation of such parabola is of the form:

$( {y - k)}^{2} = 4p(x - h)$

where (h,k)=(-5,8) is the vertex.

$|p| = | - 2 - 5| = 7$

$p = \pm7$

But the parabola opens to the left.

p=-7

The equation now becomes

$( {y - 8)}^{2} = 4( - 7)(x - - 5)$

$( {y - 8)}^{2} = - 28(x + 5)$

Which expressions are equivalent to the one below? Check all that apply.<br><br>log 2 - log 6

Marina CMI [18]

Answer:

Given the expression: log 2 -log 6

Use the logarithmic rule :

$\log(\frac{m}{n}) = \log m - \log n$

$\log x^n = n\log x$

Use the above rule to solve the expression:

$\log 2 -\log 6 = \log \frac{2}{6} = \log \frac{1}{3}$ [∴ $\log(\frac{m}{n}) = \log m - \log n$ ]

$\log 2 -\log 6 =\log 2+ \log 6^{-1} = \log 2 + \log \frac{1}{6}$ [∴ $\log x^n = n\log x$ ]

value of : log 2 -log 6 = 0.30102999566 - 0.77815125038 = -0.47712125472
