ALGEBRA! Please help me. A ball is thrown into the air with an upward velocity of 48ft/s. It’s height h in feet after t seconds is given by function h= -16t^2 +48t +6. How long does it take the ball to reach its Maximum height? What is the balls Maximum Height? Round to the nearest hundredth, if necessary.

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.
