Which graph represents the function y = cos(4x)?<br><br> Answer is graph B
VARVARA [1.3K]

Answer:

Step-by-step explanation:

Let the equation of the cosine function is,

y = Acos(Bx)

From the graph attached,

A = Amplitude = \frac{1-(-1)}{2}

   = 1

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

B = \frac{2\pi}{\frac{\pi}{2}-0}

B = \frac{4\pi}{\pi}

B = 4

Therefore, equation of the cosine wave given in the graph will be,

y = 1.Cos(4x)

y = Cos(4x)

Compute $121_3+2122_3-1200_3-2111_3$. Express your answer in base 3.
vfiekz [6]

Answer:

-221 base 3

Step-by-step explanation:

We are to calculate the value of the numbers in base 3. One of the ways to do that is to first convert each number to base 10. Do the arithmetic, then convert back to base 3.

121 base 3 +2122 base 3 - 1200 base 3 - 2111 base 3

Let's convert to base10

See attachment for details

From the workings,

121 base 3 + 2122 base 3 - 1200 base 3 - 2111 base 3 = -221 base 3

I/pai is rational or irrational?
S_A_V [24]

Answer:

Pi is an irrational number

Step-by-step explanation:

Pi is an irrational number, meaning it is a real number that cannot be stated as a fraction. That's because pi is a "infinite decimal," meaning the digits go on forever and ever after the decimal point.

Hope this helps! Have a great day!
