However, an elite group of traders who travelled from such towns as Makkah, Yathrib, Khaybar and from Yemen to the centres of ancient civilizations, including Syria, Mesopotamia and Egypt, were open to outside influences. A handful of traders were familiar with reading and writing of one sort or another. Among them were members of the Quraysh tribe and it was they who brought foreign influences into Arabian trading centres.

Expanded equation of a circle Video transcript - [Voiceover] So we have a circle here and they specified some points for us. This little orangeish, or, I guess, maroonish-red point right over here is the center of the circle, and then this blue point is a point that happens to sit on the circle.

And so with that information, I want you to pause the video and see if you can figure out the equation for this circle. Alright, let's work through this together. So let's first think about the center of the circle. And the center of the circle is just going to be the coordinates of that point.

So, the x-coordinate is negative one and then the y-coordinate is one. So center is negative one comma one. And now, let's think about what the radius of the circle is. Well, the radius is going to be the distance between the center and any point on the circle.

So, for example, for example, this distance. The distance of that line. Let's see I can do it thicker. A thicker version of that. This line, right over there. Something strange about my Something strange about my pen tool.

It's making that very thin. Let me do it one more time. So how can we figure that out? Well, we can set up a right triangle and essentially use the distance formula which comes from the Pythagorean Theorem.

To figure out the length of that line, so this is the radius, we could figure out a change in x. So, if we look at our change in x right over here. Our change in x as we go from the center to this point. So this is our change in x.Math Mountain Connections _CMU01L19 pp3 7/25/06 AM Page Math Mountain Connections Complete each Math Mountain and write all of the possible equations.
