Skeletal surveys are also used with suspected non-accidental injury in children (CE guidelines state that 19 images of the child are taken.) These are reported on by a consultant paediatric radiologist and often copies are made.
Distance Formula and Pythagorean Theorem. The distance formula is derived from the Pythagorean theorem. To find the distance between two points (x 1 ,y 1) and (x 2 ,y 2), all that you need to do is use the coordinates of these ordered pairs and apply the formula pictured below. The distance formula is. $ \text{ Distance } = \sqrt{(x_2 -x_1)^2 + (y_2- y_1)^2} $.
1. Points V, W, X, Y, and Z are graphed on a number line. The coordinate of point V is â4. What points are at a distance of 9 units from point V? Choose all answers that are correct. A. W = â13 B. X = 5 C. Y = 9 D. Z = 13 2. Points Y and Z are the same distance from point X on a number line.
