Aball is launched from a sling shot. its height, h(x), can be represented by a quadratic function in terms of time, x, in seconds. after 1 second, the ball is 121 feet in the air; after 2 seconds, it is 224 feet in the air. find the height, in feet, of the ball after 3 seconds in the air

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.
