At one farmer’s market, bananas cost $0.80 per pound. at another farmer’s market, bananas are sold in 5-pound bags for $4.50 per bag. which explains how to find the better buy?

divide 4.50 by 5 to find the unit rate for the 5-pound bag, and compare that number to $0.80 per pound.
divide 0.80 by 5 to find the unit rate for the 5-pound bag, and compare that number to $0.80 per pound.
multiply 4.50 by 5 to find the cost for 5 pounds, and compare to $4.50 per bag.
multiply 4.50 by 0.80 to find the cost for 5 pounds, and compare to $4.50 per bag.

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
