Answer:

A 36

Step-by-step explanation:

We can determine the scale factor

From triangle ABC BC =9

DEF EF = 90

We multiply by 10

The scale factor is 10

AC ( 10) = DF

We know DF = 360

b * 10 = 360

Divide each side by 10

10b/10 = 360/10

b = 36

What is the frequency of the function f(x)?<br> Express the answer in fraction form.

Reil [10]

Answer:

<u>Frequency = 1/period = $\frac{1}{8\pi }$ </u>

Step-by-step explanation:

The frequency of the sinusoidal function = 1/period

Frequency is how many the function repeats itself per unit if time i.e: per "1"

For the given graph :

$\frac{x}{4} =Bx$ , Where: B = 2π/period

period = 2π/B , B = 1/4 = 0.25

∴ Period = 2π/0.25 = 8π

∴ Frequency = 1/period = $\frac{1}{8\pi }$
