Answer:

The values of x so that y = \csc x have vertical asymptotes are -2\pi, -\pi, 0, \pi, 2\pi.

Step-by-step explanation:

The function cosecant is the reciprocal of the function sine and vertical asymptotes are located at values of x so that function cosecant becomes undefined, that is, when function sine is zero, whose periodicity is \pi. Then, the  vertical asymptotes associated with function cosecant are located in the values of x of the form:

x = 0\pm \pi\cdot i, \forall \,i\in \mathbb{N}_{O}

In other words, the values of x so that y = \csc x have vertical asymptotes are -2\pi, -\pi, 0, \pi, 2\pi.

Lady bird [3.3K]

Answer:

Step-by-step explanation:

3^x^2=9^{2x-1}\\3^x^2=(3^2)^{2x-1}\\x^2=4x-2\\x^2-4x+2=0\\X^2-4X+4=-2+4\\(X-2)^2=2\\|x-2|=\pm \sqrt{2} \\x=2+\sqrt{2},2-\sqrt{2}

Randi has a party-sized sandwich that is 3/4 yard long. She will cut it into smaller sandwiches that are each 1/12 yard long. Wh
Elena L [17]

Answer:

The expression for number of sandwiches is n=\frac{3}{4}\div\frac{1}{12}

9 small sandwiches can be made.

Step-by-step explanation:

Given:

Length of party-sized sandwich (l) = 3/4 yard

Length of each small sandwich (s) = 1/12 yard

Now, let the total number of small sandwiches be 'n'.

Now, sum of all the lengths of small sandwiches will be equal to the length of the party-sized sandwiches.

Therefore, framing in equation form, we have:

Length of large sandwich = Length of small sandwich × Total number of small sandwiches.

l=s\times n\\\\n=\dfrac{l}{s}

Now, plug in the given values and solve for 'n'. This gives,

n=\frac{3}{4}\div \frac{1}{12}\\\\n=\frac{3}{4}\times \frac{12}{1}\\\\n=\frac{36}{4}=9

Therefore, 9 small sandwiches can be made.

None, because you need to make over 15,000 a year to be taxed. And with all that money for one year would not be taxed.
