Donte simplified the expression below.
4(1+3) – (8-5)
4+37-8+51
what mistake did donte make?

he did not apply the distributive property correctly for 4(1 + 3).
he did not distribute the subtraction sign correctly for 8 – 51.
he added the real number and coefficient of 1 in 4(1 + 31).
he added the two complex numbers instead of subtracted

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?
