- I have to integrate following on the image. t belongs to <0,2π>. Could you help me, please?In North America, between 100 million and 1 billion birds die each year by crashing into windows on buildings, more than any other human-related cause. This figure represents up to 5% of all birds in the area. One possible solution is to construct windows angled downward slightly so that they reflect the ground rather than an image of the sky to a flying bird. An experiment by Klem et al. (2004) compared the number of birds that died as a result of vertical windows, windows angled 20 degrees off vertical, and windows angled 40 degrees off vertical. The angles were randomly assigned with equal probability to six windows and changed daily; assume for this exercise that windows and window locations were identical in every respect except angle. Over the course of the experiment, 30 birds were killed by windows in the vertical orientation, 15 were killed by windows set at 20 degrees off vertical, and 8 were killed by windows set at 40 degrees off vertical. a. Clearly state an appropriate…Consider a closed rectangular box with dimensions xx ft by yy ft by zz ft. If xx is increasing at the rate of 4ftmin4ftmin, yy is decreasing at the rate of 6ftmin6ftmin and zz is increasing at the rate of 3ftmin3ftmin . At what rate is the box's main diagonal changing when xx = 10 ft , yy = 16 ft and zz =5 ft.
