Acompany produces items in small batches. the machinery needs to warm up before the items can be produced. the scatterplot shows the time needed to produce batches of different numbers of items. line of best fit= y=8x+20 based on the line of best fit, which of the following statements is true? a. as the number of items in a batch increases by 1, the production time increases by 8 minutes. b. it takes about 60 minutes for the equipment to warm up c. it takes about 44 minutes for the equipment to warm up. d. as the number of items in a batch increases by 1, the production time increases by 20 minutes.

Prove that 3: 8 is equivalent to 12: 32.a. use diagrams to support your answer.

Atemperature of 1.64◦f corresponds to answer in units of ◦c.

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?
