Choose the true biconditional statement that can be formed from the conditional statement "If the area of a square is 25 square meters, then the
side length of the square is 5 meters" and its converse.
A. If the side length of a square is not 5 meters, then the area of the
square is not 25 square meters.
O B. A biconditional cannot be formed because the statement and its
converse are not logically equivalent.
C. The area of a square is 25 square meters if and only if the side
length of the square is 5 meters.
O D. The side length of a square is 5 meters if and only if the area of
the square is not 25 square meters.

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?
