Katherine recently had a swimming pool installed in her back yard. using her water hose, she can put 90 gallons of water into the pool every hour. if the pool can hold 8,100 gallons, how long will it take to fill the pool?

Because of your favorite lemonade it is $3.84 for 3 gallons. write this as an unit rate

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?

How many solutions does the nonlinear system of equations graphed below have? a. one b. zero c. four d. two
