The period of a sinusoid \cos 2(x-c) is \dfrac{2\pi}2=\pi, so any range such that \mathrm{Xmax}-\mathrm{Xmin}=2\pi will give two complete periods.

Answer:

The smallest possible domain to completely graph two periods is either [0, 2π] or [-π, π].

Step-by-step explanation:

The period of cosine function [0, 2π].

The given function is

y=5+3\cos 2(x-\frac{\pi}{3})

This function can be written as

y=5+3\cos (2x-\frac{2\pi}{3})          .... (1)

The general form of cosine function is

y=A\cos (Bx+C)+D              .... (2)

where, A is amplitude, \frac{2\pi}{B}, C is phase and D is midline.

From (1) and (2), we get

A=3,B=2C=\frac{2\pi}{3},D=5

Period=\frac{2\pi}{2}=\pi

The period of given function is [0,π]. So, the smallest possible domain to completely graph two periods is either [0, 2π] or [-π, π].

A parking garage has 500 parking spaces. One morning 330 parking spots were filled. What percent of the parking spaces were fill
blondinia [14]
Hey there! :D

So, what we need to do is make a fraction that has a denominator of 100. This is the simplest route to take.

330/500

If you took one zero away from each side, you will get an equivalent fraction:

33/50

Multiply both side by 2 to get to 100.

33*2=66 50*2=100

66/100

So, 66% percent ornament the parking lots were filled.

I hope this helps!

A number divided by 58 is close to 30.
Rom4ik [11]
X/58 (is roughly) 30
x/58 = 30
Multiply 58 on both sides.
x = 1,740

So it has to be c. 1,843

Find the next two positive and two negative angles that are coterminal with the given quadrantal angle.
adell [148]

Answer:

(1). 450 degree and 90 degree.

(2). - 270 degree and - 990 degree.

Step-by-step explanation:

So, we are given the the following data or parameters in this question or problem; A = -630 degree, and we are to look for the next two positive and two negative angles that are coterminal with the given quadrantal angle.

For the positive(+ve) angles we have that;

- 630 degree + 1080 degree = 450 degree; and - 630 degree + 720 degree= 90 degree.

For the negative(-ve) angles we have that;

- 630 degree + 360 degree= - 270 degree and - 630 degree - 360 degree = - 990 degree.
