(Ok so we learned how to do this in 3rd grade lol but it’s simple)

Steps: so look at. the number 9 think is 5 or more we raise the score.

So we make the 8 a nine because we added 1 more.

Then the rest of the numbers become 0’s.

Then you get your answer!

So, in order to round the the tens, we need to look at the ones place.

So we look at the underlined digit and see if it is 5 or higher (it is)


289<u>5</u>

So, since it's 5, we raise the next place up.  so now the 10's place has 10, so we need to raise the next place up further.


2900

Given A = {1, 2, 3), B = {2, 4, 6) and C = {1, 2, 3, 4, 5, 6), then An (Bn C) = _
sammy [17]

Answer:

  {2}

Step-by-step explanation:

A ∩ (B ∩ C) = {1, 2, 3} ∩ ({2, 4, 6} ∩ {1, 2, 3, 4, 5, 6})

  = {1, 2, 3} ∩ {2, 4, 6}

  = {2}

A ∩ (B ∩ C) = {2}

Given cos theta = - 2/5 and sin theta &lt; 0, find the six trigonometric values. I need help with this
Lena [83]

Answer:

\sin\,\theta =-\frac{\sqrt{21} }{5}

\tan\,\theta =\frac{\sqrt{21} }{2}

\sec\,\theta = \frac{-5}{2}

cosec\,\theta =\frac{-5}{\sqrt{21} }

\cot\,\theta =\frac{2}{\sqrt{21} }

Step-by-step explanation:

\cos\theta =\frac{-2}{5}

As both sin\,\theta,

\theta lies in the third quadrant.

In the third quadrant,

\sin\theta

\sin\,\theta =-\sqrt{1-\cos^2\,\theta} \\=-\sqrt{1-(\frac{-2}{5})^2 } \\\\=-\sqrt{1-\frac{4}{25} }\\\\=-\sqrt{\frac{25-4}{25} }\\\\=-\frac{\sqrt{21} }{5}

\tan\,\theta = \frac{\sin\,\theta}{\cos\,\theta }\\\\=\frac{\frac{-\sqrt{21} }{5} }{\frac{-2}{5} }\\\\=\frac{\sqrt{21} }{2}

\sec\,\theta =\frac{1}{\cos\,\theta }\\\\=\frac{1}{\frac{-2}{5} }\\\\=\frac{-5}{2}

\ cosec \,\theta = \frac{1}{sin\,\theta }\\\\=\frac{1}{\frac{-\sqrt{21} }{5} }\\\\=\frac{-5}{\sqrt{21} }

\cot\,\theta =\frac{1}{\tan\,\theta}\\\\=\frac{1}{\frac{\sqrt{21} }{2} }\\\\=\frac{2}{\sqrt{21} }

What is the following answer the equation 275 4/5 + 20.2 <br> and what is 275 4/5 - 20.2
Lady_Fox [76]

Answer: 275 + \frac{4}{5} +20.2 = 296

275 + \frac{4}{5} - 20. = 255.

Step-by-step explanation:

275 + \frac{4}{5}  + 20.2 (

= 275 + 0.8 + 20.2

= 275.8 + 20.2 = 296

275 + \frac{4}{5} - 20.2

= 5 + 0.8 - 20.2 ( \frac{4}{5} = 0.8)

=  275.8 - 20.2 = 255.

I hope this  answer your
