Answer:
The graph is shown below.
Step-by-step explanation:
Take the distance above surface of water as positive and negative for below the surface.
Given:
Distance of dock from the surface of water, 
Distance of hook from the surface of water, 
The surface of water is the reference point and hence it has a value of 0.
Now, on a number line, the values to the left of 0 mark is negative and values to the right are positive.
Therefore, H will lie on the left of 0 mark and D will lie on the right as shown below.
Answer:
-1/2
Step-by-step explanation:
its a negative slope
equation
y= -1/2x +3
Answer choice C
118.10/66.35=1.779 or 1.78
1.78x100=178
Okay so you do not really need the circle equation. if you make a triangle with it's x length as 3 and it's y length as 4, you will be able to find the third length. Do Pythagorean theorem to find the hypotenuse.
the hypotenuse will be five after you calculate it.
sin is opposite over hypotenuse or Y over R
so... the sin is 4/5
make sure you know what quadrant your triangle is in for the negatives
