On a map, each centimetre represents 50 m. The area of a rectangular park on the map is 6 cm. Tameka says that to find the area of the actual park, she can multiply the area of the park on the map by 2,500. Do you agree or disagree? Explain

Scale factor of 2 is used to enlarge a figure as shown below the area of is 18 in.²

Simplify the expression. -2/5(10+15m-20n)

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?
