You are manufacturing guttering for homes. the piece of aluminum you use to
make the gutter is a rectangular piece with the length 20 inches longer than the
width. you are going to bend along the length, four-inch pieces on each side to
form the gutter. if the gutter's volume is 1152 cubic inches, what are the
dimensions of the piece of aluminum you used?

()1. how do you find range? 2.the following set of data is to be organized into a histogram. if there are to be five intervals on the graph, what should the length of each interval be? 30, 34, 23, 21, 27, 25, 29, 29, 25, 23, 32, 31

Over which interval is the graph of f(x) = x2 + 5x + 6 increasing?

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
