Question

Name the curve with the given polar equation. If it is a conic, give its eccentricity. r = 18/6 - sin theta Choose one answer. Parabola opening downward; e = 1 Vertical hyperbola; e = 6 Vertical ellipse; e = 1/6 Horizontal ellipse; e = 1/6 Name the curve with the given polar equation. If it is a conic, give its eccentricity. r = 32/cos theta Choose one answer. Circle of radius 16 and center (16,0) Circle of radius 16 and center (0, 16) Horizontal line passing through (0, 32) Vertical line passing through (32, 0) Obtain the Cartesian equation of the curve by eliminating the parameter. x = cos t, y = 8 sin t Choose one answer. 64x2 + y2 = 64 8x2 + y2 = 8 x2 + 64y2 = 64 64x2 - y2 = 64
