Best ResponseYou've already chosen the best response.1yes right and diameter is half of radius you can use this formula to find radius \[\huge\rm r=\frac{ d }{ 2 }\]

Best ResponseYou've already chosen the best response.1well radius is 2.5 right ?

Best ResponseYou've already chosen the best response.2the point C(x,y) is 3/4 the way from A to B along a line... youc an set up 2 equations involving x and y and solve or...

Best ResponseYou've already chosen the best response.2since it is a line with a constant slope , the x and y components of that form a right triangle realizing that the relation between the lengths of each side by the pythagorean theorem c^2 = a^2 + b^2 if you shrink the hypotenuse down by 3/4 you have to do that to the other terms too

Best ResponseYou've already chosen the best response.2(3/4)c^2 = (3/4)*a^2 + (3/4)*b^2

Best ResponseYou've already chosen the best response.2so you can just look and see the change in x coordinate, and find 3/4 that, and add that to the start value

Best ResponseYou've already chosen the best response.0ok so how do i this then ?

DanJS

Best ResponseYou've already chosen the best response.2The length in the x direction from A to B is 16, 3/4 of that is 12 start at A and move 12 in the X direction, that is the x coordinate of C

Best ResponseYou've already chosen the best response.2do the same for the Y direction

Best ResponseYou've already chosen the best response.2It is just basically shrinking a right triangle by 25% then seeing where it lies on the coordinates

Best ResponseYou've already chosen the best response.0so i got that right ?

DanJS

Best ResponseYou've already chosen the best response.2or you can do it by setting up 2 equations involving x and y in the point N, then solving for the x and y

Best ResponseYou've already chosen the best response.2Distance AC = 3/4 * Distance AB and equation of the line through AB

Best ResponseYou've already chosen the best response.0ok cool but am i right ?

Best ResponseYou've already chosen the best response.2yes, you can check by just calculating the distances AB and AC and check if they are correct
