Can someone help me with this

slega [8]

Answer:

4π

Step-by-step explanation:

This is a sinusoidal function.

The period of the function is basically the length from one wave crest to the next crest. We can take any 2 subsequent crests.

Lets take our first crest to be at 3π

The next one will be at 7π, as we can see

So, the length from one crest to the next is the period, which is:

7π - 3π

= 4π

Third answer choice is right, 4π is the period.

Express 763636363636 as a rational number

shtirl [24]

$x=0.7636363\ldots$
$10x=7.636363\ldots$
$1000x=763.636363\ldots$

$\implies1000x-10x=990x=756\implies x=\dfrac{756}{990}=\dfrac{42}{55}$

What are the apparent zeros of the function graphed above ?

gregori [183]

Answer:

$-2,1,4$

Step-by-step explanation:

we have

$y=x^{3}-3x^{2} -6x+8$

we know that

The zeros of the function are the values of x when the values of the function is equal to zero

In this problem the apparent zeros are

For $x=-2$

$y=0$

For $x=1$

$y=0$

For $x=4$

$y=0$
