What is the period of the graph of y = 5 sin (pi x) + 3?

Natasha2012 [34]

Equate whats inside (arguments) $\sin$ with base period of sine function $2\pi$ and solve for x to get period,

$\pi x=2\pi\implies x=2$

So the period of the graph of the given function is precisely 2.

Hope this helps :)

Cual es la magnitud de la aceleración angular de una llanta de un automóvil que adquiere una velocidad angular de 350 rad/s en 2

drek231 [11]

Respuesta:

175 rad / s²

Explicación paso a paso:

Dado que :

Velocidad angular final = 350 rad / s

Tiempo empleado = 2 segundos

La aceleración angular, a =?

Recordar ; la aceleración angular es igual a la carga en velocidad angular con el tiempo

(velocidad final - Velocidad inicial) / tiempo empleado

Velocidad inicial = 0 rad / s

Aceleración angular = (350 - 0) / 2 = 350/2

= 175 rad / s²

sebuah topi berbentuk kerucut dengan panjang diameter 18 cm dan tinggi topi tersebut 20cm berapakah volume nya

madreJ [45]

Answer:

The area of the cone is "1,695.6 cm³".

Step-by-step explanation:

The given values are:

Diameter of cone,

d = 18 cm

then,

Radius,

r = $\frac{d}{2}$

= $\frac{18}{2}$

= $9 \ cm$

Height,

h = 20 cm

As we know,

⇒ Area of a cone = $\frac{1}{3} \pi r^2 h$

On substituting the given values in the above formula, we get

⇒ = $\frac{1}{3}\times 3.14\times (9)^2\times 20$

⇒ = $\frac{1}{3}\times 3.14\times 81\times 20$

⇒ = $3.14\times 27\times 20$

⇒ = $1,695.6 \ cm^3$

Suppose the test scores of students in a class are normally distributed with a mean of 85 and a standard deviation of 4. What is

UkoKoshka [18]

Answer:

Step-by-step explanation:

Converting it to z, we can use the formula of z-score:

z-score = $\frac{x-\mu}{\sigma}$

Where

x is the value we are checking for (here, x = 79)

$\mu$ is the mean, which is 85

$\sigma$ is the standard deviation, which is 4 now

Let's plug the information into the formula and solve for the answer:

$\frac{x-\mu}{\sigma}\\\frac{79-85}{4}\\-\frac{6}{4}\\-1.5$

B is the correct answer.
