Select the correct product. (x 2 4x 8)(2x - 1) 2x3 7x2 12x - 8 2x3 - 7x2 - 12x - 8 x2 6x 7 x2 8x - 8
kow [346]
(x^2 + 4x + 8)(2x - 1) = 2x(x^2 + 4x + 8) - (x^2 + 4x + 8) = 2x^3 + 8x^2 + 16x - x^2 - 4x - 8 = 2x^3 + 7x^2 + 12x - 8

In one day, there are two high tides and two low tides in equally spaced intervals. The high tide is observed to be 6 feet above
creativ13 [48]
Answer:  The "independent variable" is the "time" (in hours) that is plotted on the "x-axis".  Note the "time" (in hours) can be "manipulated" in the sense that is it "chosen" by the humans who are measuring the data (e.g. when to start, how many hours, and at what intervals.

The "dependent variable" is the measurement (in feet) above or below the sea level, and this is plotted on the "y-axis".  These values cannot be "manipulated" in the sense that one cannot "choose" what value or measurement the tide level would be at any particular time.

Hope these answers—and explanations—are of help to you.
Best wishes!

Solve for x squared - 12x+59=0
dalvyx [7]
We solve the equation x^2 - 12x + 59 = 0

First we use x^2 - 12x + \displaystyle\sum_{n=1}^{\sum_{i=5}^6i}\left(\frac{59}{11}\right) in order to compute our answer and then we use Justin Bieber's <span><em>I close my eyes and I can see a better day</em> </span> Theorem that says that

The\ solutions\ to\ x^2 - 12x + \displaystyle\sum_{n=1}^{\sum_{i=5}^6(i)}= 0 \\ \\ \\ \ are\ x=6+\sqrt{23}i,\:x=6-\sqrt{23}i

Here is a proof of Justin Bieber's <span>I close my eyes and I can see a better day T</span>heorem which uses the advanced techniques of mathematicians:

x^2 - 12x + \displaystyle\sum_{n=1}^{\sum_{i=5}^6(i)}= 0 \\  &#10;x^2 - 12x + 59 = 0\\ &#10;\implies x = \frac{-(-12) \pm \sqrt{(-12)^2 - 4(1)(59)} }{2(1)} \\ &#10;x = \frac{12 \pm \sqrt{144 - 236} }{2} \\&#10;x =  \frac{12 \pm \sqrt{-92} }{2}  \\&#10;x =  \frac{12 \pm 2\sqrt{-23} }{2}  \\&#10;x = 6 \pm 2 \sqrt{23} i  \\
