Need to solve and draw Q) Length of the major axis and minor axis of a conic section obtained by cutting a right circular cone by a section plane through generators is given as 120 mm and 90 mm. Plot the curve.
A network is said to be traversable if we can trace every edge without ever tracing the same edge twice. A path is said to be an Euler circuit if the network istraversable and we can start and end at the same edge. If we can visit each vert exexactly once and end back where we started, the path is said to be a Hamiltonian cycle. (See section 9.1 in your book if this is unclear)

5. Mr. Hu won the lottery and ordered two helicopters to pick him and his students up at BHSS. The two helicopters left BHSS and entered US airspace at the same time. One travelled at 250 km/h on a course of 277°.The other travelled at 200 km/h on a course of 230°. How far apart were the helicopters after 5 hours, to the nearest tenth of a kilometer? DISTANCE = SPEED X TIME. [5]
