Determine the equation of the circle in its general form, given that its centre is and its radius is 4 units. C(2,3) (1,y1) (3,y2) • Find the equation of the parabola inscribed in a circle with centre (2,3) and whose radius is equal to 2. The abscissa of the vertex is 2. We know also that the parabola intersects the circle at abscissas 1 and 3.
d { cosmos • The elliptical sign of “cosmos” restaurant measures 4 meters in length and 2 meters in width. The owner wants to attach the sign above the O’s. The sign has a width of 1.6 meters at those points. How far apart will the attachments be separated.
1 m 9 m 2 m 16 m ? • Christian wants to hit his golf ball onto the green (area with the flag). This green is elevated 2 meters from the current position of his golf ball which lies 16 meters in front of a tree that is 9 meters high. When he hits the ball, it reaches a maximum height 1 meter directly over the tree. Knowing that the ball follows a parabolic trajectory, what horizontal distance does the ball travel when it strikes the green.
