Answer:

$y = 5cos(\frac{\pi }{12}(t-6.75))+7$

Step-by-step explanation:

You have been asked to find the values in the function:

$y=Acos(B(t+C))+D$

First, calculate A, called the amplitude, as half the value from peak to peak (from lowtide to high tide):

$A = (12-2)/2=5$

Then, calculate the vertical shift D as the average value between the high tide and lowtide:

$D = (12+2)/2=7$

Then, if P is the natural period of the tide, you can calculate B, or the frequency as:

$B=\frac{\pi }{P}=\frac{\pi }{12}$

Finally you need to find C or the phase shift thinking that for negative values, the function is shifted (displaced) to the right.

C=-6.75

Use the Fundamental Theorem of Calculus to find y′. pls help

evablogger [386]

Use This Since You provided no context:

The fundamental theorem of calculus is a theorem that links the concept of differentiating a function (calculating the gradient) with the concept of integrating a function (calculating the area under the curve). ... This implies the existence of antiderivatives for continuous functions.
