Compré un celular por $560. Luego se lo vendí a Juan por $570.
Se lo volví a comprar a Juan por $580.
Y después lo volví a vender por $590,
Al final, ¿cuánto dinero gané o
perdí?

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

Noor brought 21 sheets of stickers. she gave 1/3 of a sheet to each of the 45 students at recess. she wants to give teachers 1 1/2 sheets each.

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?
