Abuilding that is 245 feet tall casts a shadow of various lengths x as the day goes by. an angle of elevation θ is formed by lines from the top and bottom of the building to the tip of the shadow. 245 ftθx find the rate of change (in radians per foot) of the angle of elevation dθ dx when x = 300 feet. (round your answer to five decimal places.)

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?
