Step-by-step explanation:
Since the buoy is going up and down, its motion is oscillatory, and therefore, it can be described by a trigonometric function.
The buoy starts at height of 0 in relation to the sea level, which means at time 
, 
, this tells us that trigonometric function modeling the buoy must be the sine function since for
, at , .
The maximum displacement of the buoy in either direction is 6 feet, this means we have
now we need to figure out 
.
The time it takes the buoy to get from its lowest point to its highest point is 4 seconds, that means the period 
of oscillation is 
seconds. The buoy returns to to the same place after one period, this means if the buoy started from 0, it will return to 0 after 8 seconds; therefore, from the we have:
Now the final equation looks like
The rational exponent expression of sixth root of f is <span>f to the one sixth power
proof
A^1/n, is called n-th root of A, for all n differ from zero</span>
Answer:
Slope-intercept form is
y = mx + b
We want to get the y by itself on one side of the equation.
0 = 18x + 6y – 2
First let's subtract 6y from both sides.
-6y = 18x – 2
Next let's divide both sides by -6.
y = (18 / -6)x - (2 / -6)
y = -3x + 1/3
...The last instructions are kind of confusing to me, but I think that is the answer you're after. :)
