The depth of the water at the end of a pier changes periodically along with the movement of tides. On a particular day, low tides occur at 12:00 am and 12:30 pm, with a depth of 2.5 m, while high tides occur at 6:15 am and 6:45 pm, with a depth of 5.5 m. Let t = 0 be 12:00 am.

Graph the equation equationthat models the situation using a graphing calculator and use it to answer the following questions.

How many times during this day is the depth at the end of the pier equal to 4 meters?

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

it alot will look like this 4.4

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

need more info

what do you mean by "representation"? graph? table? etc.
