Suppose A and B are independent events. If P(A) = 0.4 and P(B) = 0.85, what is P(A and B)?

O A. 0.17
O B. 0.51
O C. 0.68
OD. 0.34

The parabola x= √y-9 opens: a.)up b.)down c.)right d.)left

Me find the value of x each figure.

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?
