- Let's name the mid point of
as 
Then:

So the slope of the line that passes through
is:

And the slope for BC is:

As you can see, both slopes are zero, so these are horizontal lines.
First ask your self how many ounces are in 1 cup?
8 ounces
So to find how many ounces are in 8 cups, you have to multiply how many ounces in one cyp (8) by 8
8×8=64
64 ounces
Answer:
a) 
b) 
Step-by-step explanation:
Part a
Since the buoy oscillates in simple harmonic motion the equation to model this is given by:

For this case from the info given we know that:

"It returns to its high point every 10 seconds." That means period =10
, and the angular frequency can be founded like this:

Assuming that the value for the phase is
our model equation is given by:

Part b
From definition we can obtain the velocity with the derivate of the position function and if w calculate the derivate we got this:
