An airplane flies at an altitude of y = 8 miles toward a point directly over an observer (see figure). The speed of the plane is 600 miles per hour. Find the rates at which the angle of elevation θ is changing when the angle is θ = 45°, θ = 60°, and θ = 80°. (a) θ = 45° (b) θ = 60° (c) θ = 80° (Round your answer to two decimal places.) Please circle your answers. the...
An airplane flies at an altitude of y =6 miles toward a point directly over an observer (see figure). The speed of the plane is 600 miles per hour. Find the rates (in radians per hour) at which the angle of elevation is changing when the angle is 45, = 60°, and e 70°. y mi Not drawn to scale 0 45 (a) rad/hr -50 (b) 600 x rad/hr 75 70° (Round your answer to two decimal places.)
