Conic applications worksheet answers

A bridge has a parabolic arch that is 10 m high in the centre and 30 m wide at the bottom. Find the height of the arch 6 m from the centre, on either sides. A tunnel through a mountain for a four lane highway is to have a elliptical opening. The total width of the highway not the opening is to be 16 m , and the height at the edge of the road must be sufficient for a truck 4 m high to clear if the highest point of the opening is to be 5 m approximately. How wide must the opening be? At a water fountain, water attains a maximum height of 4 m at horizontal distance of 0. If the path of water is a parabola, find the height of water at a horizontal distance of 0. An engineer designs a satellite dish with a parabolic cross section. The dish is 5 m wide at the opening, and the focus is placed 1. Parabolic cable of a 60 m portion of the roadbed of a suspension bridge are positioned as shown below. Vertical Cables are to be spaced every 6 m along this portion of the roadbed. Calculate the lengths of first two of these vertical cables from the vertex. Cross section of a Nuclear cooling tower is in the shape of a hyperbola with equation. The tower is m tall and the distance from the top of the tower to the centre of the hyperbola is half the distance from the base of the tower to the centre of the hyperbola.

Conic applications worksheet answers

For the first question, we should take the information we were given to turn the parabola into the form. As the problem doesn't place the parabola at a specific location in a coordinate grid, we can assume the vertex is at 0,0. We can solve for a given the information in the problem. Visualize the parabola as symmetric about the y-axis and you will see that we know that the parabola passes through 6, 4. These two points are 12 feet apart wide and 4. Plugging 6 for y and 4. Again, since we can assume the parabola is centered at 0,0 , h and k are both 0. The receiver should be 2 feet away from the vertex.
