Question 113033: This is going to be difficult to explain but I will do my best. This is a CNC problem (computer numerical control). It states: Determine X-Y locations for drilling 6 holes. The origin or 0,0 point is in the center. The first hole is located on the top of y axis.
Assuming that the radius is 5.50 inches, then the first hole location would be XO, Y 5.50. The second hole location would be 60 degrees from the first. Calculate the X ( ), Y ( ) for each hole.
Please help me I am so lost and confused.

Question 118123:
Find the distance between points (-1,-1)and (2,5)
I am really not sure what I did wrong on this one. It was a multiple choice question. A is 6 square root of 5. B is 3 square root of 6. C is 5 square root of 6. And D is 6 square root of 3. I came up with C. 5 square root of 6. Please tell me what I did wrong....

Question 121952This question is from textbook Glencoe Mathematics Geometry
: Find the value of x so that the line containing points at (x,2) and (-4, 5) is perpendicular to the line containing points at (4,8) and (2,-1).
I have determined that the slope for the line containing (4,8) and 2,-1 is 9/2 and thus the slope for the perpendicular line would be -2/9. I figured that if I used the y2-y1 over x2-x1 and set that = to -2/9 that I would get the answer and it just is not working. The book says that the answer is 9.5. Can you help?This question is from textbook Glencoe Mathematics Geometry
