Tides are cyclical phenomena caused by the gravitational pull of the sun and the moon. on a particular retaining wall, the ocean generally reaches the 2.1 m mark at high tide. at low tide, the water reaches the 0.8 m mark. assume that high tide occurs at 12: 00 p. m. and at 12: 00 a. m., and that low tide occurs at 6: 00 p. m. and 6: 00 a. m. what is the height of the water at 9: 30 a. m.?

answer: the correct one is a

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

40 x 50 = 2000
