The midpoint of that segment is (3, -2) - all you do is take the average of the x coordinates and the average of the y coordinates.\n\nThe slope of that segment is found by\n\nm = (y2 - y1)/(x2 - x1)\n= (1 - (-5))/(4 - 2)\n= 6/2\n= 3\n\nSince you're looking for a line perpendicular to this one, take the slope, invert it, and change the sign.  So the slope of the new line will be -1/3.\n\nNow you have a point and a slope for the new point: m = -1/3, and point (3, -2).  Use the point-slope formula to find the equation of the line:\n\ny - y1 = m(x - x1)\ny - (-2) = (-1/3)(x - 3)\ny + 2 = (-1/3)x + 1\ny = (-1/3)x - 1

I know how to do it, but it's going to cost me a lot of work, and sorry I don't have the time!\n\nI can give you some tips to start off though:\n\nDraw an x,y diagram where the center of the circle is the origin. Draw AB as a horizontal baseline which is 21 below the origin.\n\nThen you will have to create functions for the circle and then for the lines that have the tangents with the circle that together form the triangle. Particularly the formulas for the triangle lines will be hard.\n\nYou will have to calculate at which other points than P the triangle lines touch the circle. For that you will need the derivative of the function for the circle.\n\nEnglish is not my native language, so I hoped I used the correct English terminology. Good luck!\n\nP.S.:  aytu_y, what you say about equilateral triangles is correct, but it doesn't work in this case because here point P is not in the middle! (PA = 23 while PB = 27)

Bring in items with shapes.....ice cream cone, cookie sheet, book, rubrics cube, etc.  Also, trace these shapes and have kids go on geometric shape hunt to try to find the shapes in school. \nFollow up with some type of worksheet.

Use the FOIL method; First, Outer, Inner, Last.\n\nFirst, n * n\n\nOuter, n * 5\n\nInner, n * 7\n\nLast 7 * 5.\n\nThen add them all together.\n\n22 NOV 06, 0420 hrs, GMT.

Rewrite the word problem in math symbols\n\nThey tell you V = s^3 and\nV = 729 cm^3\n\nSo, 729 cm^3 = s^3\nTake the cuberoot of each side:\n\ncuberoot(729 cm^3) = cuberoot(s^3)\n\n9 cm = s

Do your own homework sweety. Go to the teacher the next day and say you dont get it or even ask a parent. Dont cheet online, I am a teacher and I used to give my children that problom. Just be truethful, what most kids dont do is ask a parent, go to your mom or dad, or get toothpicks and do the real thing!

Not a site, but I suggest you invest in something called Mathcad.\nTeach, please note, it is a site not a sight! Unless you were 'looking' for the answer... sorry!

Here is a way to find more problems than you probably want to do - go to Google, and search for:\n\n"algebra I practice questions"   \n\n(grade 9)\n\n"geometry practice questions"\n\n(grade 10)\n\nBe sure to use the quotes.  I just tried and hundreds of nice sites woth good problems appeared.  Good for you for wanting to learn on your own!

The two "triangles" are not exact triangles, but rather are quadrilaterals.  The error in representation actually adds up to be one unit.  I have done the caculations in AutoCAD, and it turns out to be one square unit missing causing the extra space.

Check the image I attached...\n\nHere I've made the polygon into a complete rectangle.  The figure in red is the added triangle.  It has sides 6 and 8 and is a right triangle.  If you remember your Pythagorean ratios, you should know 3-4-5 and 6-8-10.  Or you can prove it using:\n\n6² + 8² = x²\n36 + 64 = 100\nx² = 100\nx = 10\n\nTo get the perimeter, just add up the sides:\nPerimeter = 1 + 10 + 9 + 4 + 10\nPerimeter = 34 units\n\nTo get the area, take the big rectangle (9 x 10) and remove the area of the triangle (1/2 b * h = 6 x 8 / 2)\nArea = 9 x 10 - (6 x 8)/2\nArea = 90 - 24\nArea = 66 sq. units
