Answer:
8%
Step-by-step explanation:
We will use the equation provided to solve this problem.

Lets plug in the values:
First, divide both sides by 800.
Multiply x by 1

Now, we multiply .08 by 100 to get our interest rate:
(.08)100 = 8
The interest rate is 8%
Answer:
.09ft^2
Step-by-step explanation:
Answer/Step-by-step explanation:
Total Distance = 3Ft
a) Determine the amplitude and period of a sinusoidal function that models the bobbing buoy.
Amplitude = 3/2 = 1.5 period = 10 second
No ph. Shift
b) Write an equation of a function that models the buoy with x=0 at its highest point.
y= 1.5 cos (
)
