Basically (-3)^2 is literally negative three times negative three so 9
In -3^2 the calculator understands
3^2 which is 9 and then makes it negative (-9) because it doesn't see the - as part of what is being squared

The answer to this question
levacccp [35]
The question gives us that cot ∅ = 1.5, and we need to find tan ∅ (∅ being theta). So, cotangent, which is <em>cot</em>, is equal to adjacent over opposite, and tangent, abbreviated <em>tan</em>, is equal to opposite over adjacent. Basically, we need to take the inverse of the given value for <em>cot</em><em>. </em>Doing so gives us 1/1.5, which is approximately 0.667. Therefore, the answer to your query is A. Hope this helps and have a great day!

Jay has an album that holds 600 coins. Each page of the album holds 6 coins. If ​39% of the album is​ empty, how many pages are
Nutka1998 [239]

9514 1404 393

Answer:

  61

Step-by-step explanation:

If there are 6 coins on each page, then the number of pages for 600 coins is ...

  (600 coins)/(6 coins/page) = 100 pages

__

If 39% are empty, then 100% -39% = 61% are filled.

The number of filled pages is ...

  61% × 100 = 61/100 × 100 = 61 . . . . pages filled

_____

<em>Comment about percent</em>

You can think of the percent symbol (%) and "per 100" (/100) as being interchangeable. 61% = 61/100

("Cent" is used to signify one of 100 parts. A cent is 1/100 of a dollar, for example. In land area, a cent is 1/100 of an acre. Then, "percent" can be thought of as "per cent" or "per 100 parts".)
