--On CH build a square having CH as one side. Label the top right vertex I and the top left vertex J. You have created rectangle EGIJ.

--Moving counter-clockwise reapeat the process of adding a new square on the long side of the last rectangle until u have expanded ur construction as far as your paper will allow. FOr perposses of comunication, countinue to label new vertices alphabetically in a counter-clockwise direction.

I have no idea how to draw this. Can someone help me!

Let f(x) = -3(x+2)(x-4)(x-2)(x+6)


----
so i need to find the zeros of that, i expanded it and put it in the form: 3(5x^2 + 16x -12) ... i dont know if that's right. now how do i find the zeros? the answer is -6, -2, 2 and 4.

how do i get it? show work plz!! thx for the help..


Also, how do you find the maximum number of turning points ??

Job in the Bible speaks about an "empty space" (Job 26:7).Although the Heavens are filled with stars where ever the telescope can reach,it seems that behind the North star there is an empty space.for that reason it has been suggested that this could be the third heaven.One of the most inspiring and thrilling of recent disclosures to astronomers is that there is a great empty space in the North in the Nebulae of the constillation Orion.A heavenly cavern so gigantic that the mind of man cannot even comprehend and so brilliantly beautiful that words cannot adequately describe it.What has been found,Job wrote about;"He stretched out the north over the empty place..."(Job 26:7).All astronomers agree there is a huge opening over the constellation Orion which is perhaps more than 16 trillion,740 billion miles in diameter.This opening is 90,000 times as wide as our earth's orbital path.However,past it's size is it's beauty.Its colors are unlike any here on earth.The photographs (I'm looking for) of its opening reveal the interior of a cavern so great that our entire solar system would be lost in it.The interior is like that of light shining and glowing behind the clear walls of ivory and pearl,studded with millions of diamonds like shining stars.There must be some reason why all this grandeur is lavished on one area in the Heavens.They give the appearance of a pavement of starry sand.Astronomers although not religious,say they feel like they are in some almighty presence.

If a plane starts at the equator and flies northeast (45 degrees north of east) continuously, how far does it fly until it reaches the north pole?
Assume the plane is a mathematical point and the earth is a perfect sphere of radius 4000 miles.
Can this problem be solved without using calculus to compute arc length of a curve in spherical coordinates?
