Misha’s group was asked to write an expression equivalent to 7 y squared z + 3 y z squared minus 3. When Mr. Chen checked their answers, he found only one to be correct. Who had the correct answer? Misha’s Group Student Equivalent Expression Misha 4 y squared z minus 5 + 3 y z squared minus 3 y squared z + 2 Juan 9 y squared z minus 2 + 3 y z squared minus 2 y squared z + 1 Joe 7 y squared z + y z squared + 2 + 2 y z squared + 1 Helena 7 y squared z + 6 y z squared minus 5 minus 3 y z squared + 2 Misha Juan Joe Helena

Jacob signs up to work for 2 1/2 hours at the school carnival. if each work shift is 3/4 hour, how many shifts will jacob work? (i just want to double check : |, for anybody that responds! : )

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?
