There are 15 playing cards in a bag: 6 are kings, 4 are aces, and 5 are queens. Jay picks one card from the bag, does not replace it, and then picks another. Write the theoretical probability for : P(ace, king)

Aline has a slope of 1/4 and passes through point (0.4,-1/2). what is the value of the y-intercept?

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?

Explain how you divide powers with like bases. discuss why the bases have to be the same. how are these rules similar to the rules for multiplying powers with like bases.
