Weba) are somewhat arbitrary in assigning independent and dependent variables to the horizontal and vertical axes. b) always put the dependent variable on the horizontal axis and the independent variable on the vertical axis. c) measure the slope of a line differently than do mathematicians. WebIn this system, an arbitrary point O (the origin) is chosen on a given line. The coordinate of a point P is defined as the signed distance from O to P , where the signed distance is the …

WebIn the diagram, point B is a point of tangency. Find the radius r of ⊙C. SOLUTION You know from the Tangent Line to Circle Theorem that AB — ⊥ BC —, so ABC is a right triangle. You can use the Pythagorean Theorem (Theorem 9.1). AC2 = Pythagorean TheoremBC2 + AB2 (r + 50)2 = r2 + 802 Substitute. r2 + 100r + 2500 = r2 + 6400 Multiply.

The result includes the case of the field on the axis of the rod beyond one of its ends, and the case of an infinitely long rod. The general answer is most conveniently expressed in terms of the linear charge density λ; for a finite rod of length L and total charge Q, that charge density is equal to Q/L.
