Answer:

Tan and cos

Step-by-step explanation:

In the third quadrant, tan is positive and cos is negative. Quadrant is a circle divided into four potion in which in each portion some of the trigonometry function are positive and others negative. This is important in determining and converting any negative angle to positive value. The value of the angle in the third quadrant is represented as (180+theta) where theta is the angle given in question.

Note that all the trigonometry values are all positive in the first quadrant thereby making tan positive in the first quadrant. Also, the only value positive in the third quadrant is tan making both sin and cos negative.

I think you are asking to sort them according to the shortest to longest in length. For this, it would be helpful to write the fraction into decimal. The equivalent values are as follows:

5/6 = 0.83
5/3 = 1.67
3/2 = 1.50

Therefore, the correct sorting would be as follows:

first yarn
third yarn
second yarn

Hope this answers the question. Have a nice day.

Which expression is equivalent to 15a^8b^4/5a^4b?<br> 3a^2b^4<br> 3a^4b^3<br> 10a^4b^3<br> 10a^4b^4
EleoNora [17]

Answer:

3 a^12 b^5

Step-by-step explanation:

Simplify the following:

(15 a^8 b^4 a^4 b)/5

15/5 = (5×3)/5 = 3:

3 a^8 b^4 a^4 b

3 a^8 b^4 a^4 b = 3 a^(8 + 4) b^(4 + 1):

3 a^(8 + 4) b^(4 + 1)

4 + 1 = 5:

3 a^(8 + 4) b^5

8 + 4 = 12:

Answer: 3 a^12 b^5
