Convert the polar equation $$r=2(h \cos \theta+k \sin \theta)$$ to rectangular form and verify that it is the equation of a circle. Find the radius of the circle and the rectangular coordinates of the center of the circle.
A moving conveyor is built so that it rises 1 meter for each 3 meters of horizontal travel. (a) Draw a diagram that gives a visual representation of the problem. (b) Find the inclination of the conveyor. (c) The conveyor runs between two floors in a factory. The distance between the floors is 5 meters. Find the length of the conveyor.
Determine whether the statement is true or false. Justify your answer. If the vertex and focus of a parabola are on a horizontal line, then the directrix of the parabola is vertical.
Determine whether the statement is true or false. Justify your answer. If \(D \neq 0\) and \(E \neq 0,\) then the graph of \(x^{2}-y^{2}+D x+E y=0\) is a hyperbola.
In Exercises \(91-116\), convert the polar equation to rectangular form. $$r=\frac{1}{1-\cos \theta}$$
