The figure shows a trapezoid with a height of 4 units. The area of the trapezoid is 20 square units. Select all of the dimensions for a and b that
would represent the trapezoid.
a = 3 units. b = 2 units
a = 6 units, b = 4 units
a = 12 units, b = 8 units
a = 7.5 units, b = 2.5. units
a = 4 units, b = 1 units
a = 23 units, b = 17 units

Given abcd ac=38 and ae=3x+4 find the value of x

Solutions for 2x+7 less than or equal to 3x-5

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?
