Find the amplitude and period of f(t)=1/2sin 3t

Option A

The Amplitude is

Then the period is

Step-by-step explanation:

The general sine function has the following form  

Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.  

is the period: time it takes the wave to complete a cycle.

k is the vertical displacement.

In this case we have the following function

Thus:

Then the period is

The Amplitude is

The answer is Option A

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.
