A camera postioned 400 ft from the base of a skyscraper, is filming the progress as a
daredevil attempts to scale the wall of a skyscraper. The climber is moving up vertically at a rate of 16 ft/min. What is the rate of change of the camera angle when the climber is 300 ft up the building?
•16/625 rads / min
•1/625 rads / min
•1/320 rads / min
•3/5 rads / min

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.
