Find the height of the pyramid     to be sqrt 108         (use pythag theorem)

volume = 1/3 (12)(12) (sqrt(108))    units³

Well.... you don't KNOW this one is different as the numbers are missing....BUT the OTHER solutions will show the method....which should be enough to help solve this one !    ~ EP

This Q has been posted MANY times.... suggest you do a search to get a quick answer  

every 5 days  (x) it goes up 5  cases  y     slope =  5/5 = 1

From 12 o'clock the minute hand will be at  90 degrees

   the hour  hand will be at    5 *30 + 30 * 15/60 = 157.25        difference = 67.5 degrees     ( as Guest posted)

p = k/ q²   means that

p q^2 = k    the proportionality constant

19(8^2) = k =1216

p = 1216/ (3²)    = 135.1111

3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 = 3 ⁸  =__________________   ( it is NOT a common FRACTION)

How to get -3 root of 2. If I only have root of 2

\(\sqrt{-3}\)    = i  \(\sqrt{3}\)   = 1.73205 i

Several ways to do this:

  find the derivative and set = 0

    0 = -4x + 18       shows x = 4 1/2      use this value in the original equation to find the 'y' coordinate

Arrange  the parabolic equation into vertex form

    -2 ( x^2 - 9x)    - 15

    -2 ( x -4.5)^2  +25.5                shows  h,k   =   4.5, 25.5

Third way

  max will occur at   - b /2a   = -18/(2*-2) = 4 1/2     use this value in the original equation to calculate 'y'
