An airplane is heading north at an airspeed of 500 km/ hr, but there is a wind blowing from the northwest at 30 km/ hr. The plane will end up flying degrees off course The plane's speed relative to the ground will be km/ hr Add Work Submit Question 0 Question 15 [Z 8 pts '0 5 Details Find the parametric equations for the position of a plane that rises 3 feet for every 40 feet it travels horizontally if the speed of the plane is 329 feet per second in the direction it is traveling (not horizontallty and not vertically). Assume that at t = 0 seconds, the plane was 293 feet above the ground. And let the horizontal distance at t = 0 be 0. Assume = 0 corresponds to the given point and increases as :1: increases. mm = C] yo = [:1 An ellipse has vertices at (0, 9) and (0, 9) and passes through the point (2, V 72). Find the equation in standard form: Report the location of the foci (separated by a comma): Add Work Submit Question 0 Question 13 B 8 pts '0 5 (D Details To estimate the height of a building, two students find the angle of elevation from a point (at ground level) down the street from the building to the top of the building is 37 . From a point that is 300 feet closer to the building, the angle of elevation (at ground level) to the top of the building is 45 . If we assume that the street is level, use this information to estimate the height of the building. The height of the building is feet
