\fFind an equation of the circle whose diameter has endpoints (6, - 1) and (-4, - 1). 0=0 X 5Find the vertex, focus, directrix, and axis of symmetry of the parabola. (x + 5)- =-5(1+3) Vertex: X 5 Focus: Directrix: O O y = Axis of symmetry: ( x =The parabola in the figure below has vertex (0, G) and focus F(O, 3). Its directrix is the horizontal line that passes through (0, 3). The point R(x,_1=) is a point on the parabola that is above and to the right of the focus. The point I lies on the directrix, and E is perpendicular to the directrix. (a) What are the coordinates for the point I ? [(Choose one) 1' l (b) Write the expressions for the distances FR and TR. FR=|:| TR=D (c) From the definition of a parabola, which of the following must be true? [(Choose one) 1' l (d) Use the above to write an equation for the given parabola solved ..P for .1". The arch of the bridge below is half an ellipse, a "semi-ellipse". As shown in the figure below, the arch is 162 m long and has a height of 48 m at the center. The point p is located 16 m from the center. Find the height of the arch above point p. Round your answer to the nearest hundredth. Do not round any intermediate computations. 48 m X 5 16 m center P 162 m
