Find the equation of the circle with given center and radius \(r\). $$(0,0) ; \quad r=\sqrt{3}$$
Find the center and radius of the circle whose equation is given. $$x^{2}+y^{2}+10 x-75=0$$
If \(P\) is a point on a circle with center \(C\), then the tangent line to the circle at \(P\) is the straight line through \(P\) that is perpendicular to the radius \(C P\). In Exercises \(67-70\), find the equation of the tangent line to the circle at the given point.) \(x^{2}+y^{2}+6 x-8 y+15=0\) at (-2,1)
Find the distance between the given numbers. \(\sqrt{2}\) and \(\sqrt{3}\)
(a) Solve \(x^{2}+5 x+2=0\) (exact answer required). (b) If you have one of the calculators listed below, use its polynomial solver to solve the equation in part (a). Does your answer agree with the one in part (a)? Calculator (TI- \(84+\)) (TI- 86) (TI-89) (Casio 9850) (HP-39gs) Use this menu/choice (APPS/PolySmlt") (POLY) (ALGEBRA/Solve^t) (EQUATION (Main Menu) (MATH/POLYNOM/Polyroor) (c) Use the solver to solve \(3 x^{4}-2 x^{3}-5 x^{2}+2 x+1=0\)
