Suppose the depth of the tide in a certain harbor can be modeled by y = 23 - 5 cos la wh
where y is the water depth in feet
and t is the time in hours. Consider a day in which t = 0 represents 12:00 midnight. For that day, when are high tide and
low tide and what is the depth of each?

step-by-step explanation:

i think because what else can be a sample of every member

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
