The ocean rises and falls each day due to tides. The Bay of Fundy in Canada has some of the highest tides in the world. Its tidewater rises about 53.478 feet and falls the same amount afterward, twice a day. Question 1
Part A

Write an expression that can be used to find the total feet the tide changes each day.

y(x) = 53.478 sin (4π x)

where x is the number of days and y is the total fall and rise in the tides.

yo answer should be 6 if im not mistaken

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
