6 0

Answer:

42

Step-by-step explanation:

1/6in made into a decimal is 0.16666... so I rounded it to 0.17.

256 divided by 6.17= 41.9773096 which rounded to the nearest whole number is 42.

If 5 becomes 11 and 12 becomes 25, what does 15 become?
Amiraneli [1.4K]

Answer:

31.

Step-by-step explanation:

5+5 = 10 + 1 = 11

12 + 12 = 24 +1 = 25

15 + 15 = 30 + 1 = 31

I don't know I tried to see if that was the pattern. It checks out math wise.

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
astra-53 [7]

Answer:

3\pi \rightarrow y=2\cos \dfrac{2x}{3}\\ \\\dfrac{2\pi }{3}\rightarrow y=6\sin 3x\\ \\\dfrac{\pi }{3}\rightarrow  y=-3\tan 3x\\ \\10\pi \rightarrow y=-\dfrac{2}{3}\sec \dfrac{x}{5}

Step-by-step explanation:

The period of the functions y=a\cos(bx+c) , y=a\sin(bx+c), y=a\sec (bx+c) or y=a\csc(bx+c) can be calculated as

T=\dfrac{2\pi}{b}

The period of the functions y=a\tan(bx+c) or y=a\cot(bx+c) can be calculated as

T=\dfrac{\pi}{b}

A. The period of the function y=-3\tan 3x is

T=\dfrac{\pi}{3}

B. The period of the function y=6\sin 3x is

T=\dfrac{2\pi}{3}

C. The period of the function y=-4\cot \dfrac{x}{4} is

T=\dfrac{\pi}{\frac{1}{4}}=4\pi

D. The period of the function y=2\cos \dfrac{2x}{3} is

T=\dfrac{2\pi}{\frac{2}{3}}=3\pi

E. The period of the function y=-\dfrac{2}{3}\sec \dfrac{x}{5} is

T=\dfrac{2\pi}{\frac{1}{5}}=10\pi

How many zeros does the function f(x) = 3x12 − 17x8 + 11x4 − 6x + 23 have?
Lemur [1.5K]
How many zeros does the function f(x) = 3x12 − 17x8 + 11x4 − 6x + 23 have? 

<span>Answer: the third option (12 zeroes..). </span>

<span>Use ^ to denote an exponent.. </span>

<span>f(x) = 3x^12 - 17x^8 + 11x^4 - 6x + 23.. </span>


<span>We know from that fact that the number of zeroes (real or complex) in a polynomial is the same as the degree of the polynomial.. </span>

<span>The degree is the greatest/highest power of the terms, which in this case is 12 (since 12 is the greatest exponent..).. </span>

<span>The degree is 12, thus it means there are 12 zeroes.. </span>


<span>Answer: the third option (12 zeroes)...</span>
