Problem 1

Match the parabola to the equation. (GRAPH CAN'T COPY) $$y^{2}=4 x$$

Problem 1

The coordinates of a point in the \(x y\) -coordinate system are given. Assuming that the \(X Y\) -axes are found by rotating the \(x y\) -axes by the given angle \(\theta\), find the corresponding coordinates for the point in the \(X Y\) -system. $$(2,4), \theta=45^{\circ}$$

Problem 1

Identify the conic section as a parabola, ellipse, circle, or hyperbola. $$x^{2}+x y-y^{2}+2 x=-3$$

Problem 1

Graph the curve defined by the parametric equations. $$x=t+1, y=\sqrt{t}, t \geq 0$$

Problem 1

Find the polar equation that represents the conic described (assume that a focus is at the origin). Conic Ellipse Eccentricity \(e=\frac{1}{2}\) Directrix \(y=-5\)

Problem 2

The coordinates of a point in the \(x y\) -coordinate system are given. Assuming that the \(X Y\) -axes are found by rotating the \(x y\) -axes by the given angle \(\theta\), find the corresponding coordinates for the point in the \(X Y\) -system. $$(5,1), \theta=60^{\circ}$$

Problem 2

Solve the system of equations by applying the elimination method. $$\begin{array}{rr}x^{2}+y= & 2 \\\2 x+y= & -1\end{array}$$

Problem 2
