Question 1195447: 1. A satellite is orbiting Earth on a path described by x2+y2=45 000 000. A second satellite is in the same plane and is occupying the point (12 504, 16 050). Determine if the orbit is narrower, the same, or wider than the first satellite's.
2. Write the equation for a circle centered at the origin with x-intercepts of (-9,0) and (9,0).Use ^2 for squared, ^3 for cubed, etc.

Question 1131849: Points B(b,0) and C(c,10) are to be placed on this graph so that the distance from A to B to C to D is a minimum. Find the value of b.
Note: point A is at (0,4) and point D is at (8,9)'
I got a hint from my teacher saying to reflect point A on the x axis. I don�t know what to do from there.

Question 1199836: Original data Line of "best guess" Line of best fit
Mph greater than speed limit Number of citations Outputs Residuals Outputs Residuals
5 3
7.5 6
10 10
15 5
20 6
Use a calculator or online resource to find the line of best fit. Note that values have been rounded.
y = 0.7 x - 5.2
y = 0.7 x + 5.2
y = 0.07 x + 5.2
y = 0.07 x - 5.2
