(-3,4) or x = - 3, y = 4
Step-by-step explanation:
Answer:
2/10 .02
Step-by-step explanation:
Answer:
h=52 and h is the shortest
Step-by-step explanation:
180-f-g=h step 1. -f from 180
180-60=120 step 2. -g from 120
120-68= 52
h=52 degrees
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:


The revenue earned is
R=$5804.45. Option D
This is further explained below.
<h3>What is
