2) Graph the equation. y² = 12x 5 10 -10 -5 5 + 10 x

15) Solve the triangles if possible. B = 11°, b = 15.5, a = 40.62

10) Find the exact value of the expression. tan−1 [tan (~ 7}]] 8

12) The point (-15, -8) is on the terminal side of an angle in standard position. Determine the exact values of the three trigonometric functions sine, cosine, and tangent of the angle 0.

6) Find the center, foci, and vertices of the ellipse. = 9 49 1

1) Find an equation of the parabola with a focus at (0, 4) and directrix the line y = -4, and state the two points that define the latus rectum. A) x² = 16y; latus rectum: (4, 8) and (-4,8) B) x² = 4y; latus rectum: (2, 4) and (-2, 4) C) x² = 16y; latus rectum: (8, 4) and (-8, 4) D) y² = 4x; latus rectum: (9, 2) and (-9, 2)

4) A spotlight has a parabolic cross section that is 6 ft wide at the opening and 2.5 ft deep at the vertex. How far from the vertex is the focus? Round answer to two decimal places. A) 0.90 ft B) 0.21 ft C) 0.52 ft D) 0.26 ft

5) Match the graph to its equation. 10+ -10 -5 5 + 10 x -10
