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

Write the point slope equation of the line through (7,-2) with slope of 1/2.

ahrayia [7]

Answer:

y = 0.5x - 5.5

Step-by-step explanation:

slope = 0.5, so this is the x coefficient.

y intercept = -2 - (7 x 0.5) = -5.5
