On a trip of d miles to another city, a truck driver's average speed was x miles per hour. On the return trip the average speed was y miles per hour. The average speed for the round trip was 60 miles per hour. (a) Verify the following. y = 30x x−30 What is the domain? x < 30 x > 30 x ≠ 30 x > 0 R (b) Complete the table. (Round your answers to three decimal places. ) (c) Find the limit of y as x → 30+. (If the limit does not exist, enter DNE.)

An airplane flies at an altitude of y = 5 miles toward a point directly over an observer (see figure). The speed of the plane is 500 miles per hour. Find the rates (in radians per hour) at which the angle of elevation θ is changing when the angle is θ = 45∘, θ = 60∘, and θ = 80∘. (a) θ = 45∘ rad/hr (b) θ = 60∘ rad/hr (c) θ = 80∘ (Round your answer to two decimal places.) rad/hr
