The most generic sine function you can write is
Of all these constant, affects the amplitude,
affects the wave length,
and
cause horizontal/vertical translation.
In your case,
And we are interested in the amplitude, so we focus on
The amplitude of the standard sine function is 1, so when you multiply by , the new amplitude is
itself. In our case
, so the amplitude is 4.
The largest radius for the swimming pool is 15.1 feet
Step-by-step explanation:
Step 1:
Circumference of the circular swimming pool built by Dan = 95 feet
We need to determine the largest radius for the pool.
Step 2 :
Circle's circumference is given by 2πr
Where r represents the radius
This shows that the radius is in direct proportion to the circumference. Hence the radius corresponding to the maximum circumference will be the largest possible radius
So we have 2πr = 95
=> r =
=> r = ×
where
=> r = 15.1 feet (rounded off to tenth of a foot)
Step 3 :
The largest radius for the swimming pool is 15.1 feet
