Determine the amplitude or period as requested . Amplitude of y = - 1/5 * sin x a - 1/5 1/5 b 5 d. pi/5

Brrunno [24]

Answer:

The amplitude is 1/5

Step-by-step explanation:

Given

$y = -\frac{1}{5}\sin(x)$

Required

Determine the amplitude

The general cosine function is:

$y = A\sin(k(x + c)) +d$

Where

$Amplitude = |A|$

Compare $y = A\sin(k(x + c)) +d$ and $y = -\frac{1}{5}\sin(x)$

$A = -\frac{1}{5}$

So:

$Amplitude = |-\frac{1}{5}|$

$Amplitude = \frac{1}{5}$
