Enter the amplitude of the function f(x) . f(x)=3/4cos(3x)+4
Alisiya [41]

Answer:

The amplitude is \frac{3}{4}

Step-by-step explanation:

Let f(x) be a sinusoid function that has the following format:

f(x) = bsin(wx + s) + h

Then b is the amplitude of the function

h is the vertical displacement of the wave

s is the phase angle

\frac{2\pi}{w} is the period.

In this problem f (x) = \frac{3}{4}cos(3x) +4

Then \frac{3}{4} = b

Therefore the amplitude of the function is \frac{3}{4}

The amplitude is a measure of the vertical size of the sinx wave

What graph passes the vertical line test?
Marianna [84]

Answer:

The fourth image, or D.

Why?

If you had a ruler and placed it on the grid vertically and moved the ruler left to right, pictures A, B, and C, all have two points that lay on the same X point.

Picture D is the only one that has no points that lay on the same X point, thus making it the right answer.

Thank you for reading into this.

(Hope this helps you! ^^)

Is it possible to find another line that’s parallel to 3x+9y=1 and passes through (0, 1/9)
LuckyWell [14K]

Answer:

no it is not

Step-by-step explanation:

3x+9y=1 simplified is

9y=-3x+1

y=-1/3x+1/9

this is the exact same equation as 3x+9y=1, so you cannot find another line thats parallel to it and passes through that same point (it'll always be that point)
