What is the amplitude of y = 4sin3x? 1/2 2 3 4

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.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
