Answer:

Step-by-step explanation:

The equation of a circle in standard form:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

We have the equation:

$x^2+y^2=100\\\\(x-0)^2+(y-0)^2=10^2$

Therefore we have

the center (0, 0)

radius r = 10

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 = $\frac{1}{8\pi }$

Llana [10]

Answer:

x = 11

Step-by-step explanation:

Given :

AB = x + 5

BC = 2(x - 3)

AB = BC

x + 5 = 2(x - 3)

x + 5 = 2x - 6

5 + 6 = 2x - x

11 = x

x = 11
