Two planes leave an airport at the same time, traveling on runways that have an angle of 42° between them. If one plane travels at an average speed of 220 mph and the other plane travels at an average speed of 280 mph, how far apart are the two planes after 4.5 hours? (Round to one decimal place.)

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
