Avalve in a full 6000 gallon water tank is slowly opening. water flows out of the tank through the valve. the flow rate in gallons per hour is given by the function f(t)=300t2 where t is in minutes. how much water flows out of the tank in the first 7 minutes? how many minutes does it take for the tank to empty completely?

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.
