The number of streetlights in a town is growing linearly. 5 month ago (N=0) there were 120 lights. Now (N=5) there are 140 lights. If this trend continues, (a) Find an explicit formula for the number of lights in month N. Note: Webwork is case-sensitive here, so if you use the variable N in your answer you must keep it capitalized. Py = (b) It will take ! months to reach 156 lights.

Can Dogs Understand Human Cues? EXPLORATION Dogs have been domesticated for about 14,000 years. In that time, have they been able to develop an understanding of human gestures such as pointing or glancing? How about simi lar nonhuman cues? Researchers Udell, Giglio, and Wynne tested a small number of dogs in order to answer these questions. In this exploration, we wll first see whether dogs can understand human gestures as well as nonhuman gestures. To test this, the researchers positioned...
