A street light is at the top of a pole that has a height of 14 ft . A woman 4 ft tall walks away from the pole with a speed of 5 ft/s along a straight path. How fast is the tip of her shadow moving when she is 46 ft from the base of the pole?

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
