The entrance to a tunnel is in the shape of a semiellipse over a 24 -ft by 8 -ft rectangular opening. The height at the center of the opening is 14 ft . a. Determine the height of the opening at a point 6 ft from the edge of the tunnel. Round to 1 decimal place. b. Can a 10 -ft high truck pass through the opening if the truck's outer wheel passes at a point 3 ft from the edge of the tunnel? c. Set up a coordinate system with the origin placed on the ground in the center of the roadway. Write a function that represents the height of the opening h x (in ft) as a function of the horizontal distance x (in ft) from the center.

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.

a) Find for both planes the Hessian normal form and for plane 1 in addition the parameter form.
b) Use the cross product of the two normal vectors to show that the planes intersect in a line.
c) Calculate the intersection line.
d) Calculate the intersection angle of the planes. Make a sketch to indicate which angle you are
calculating.
