Answer:
2/7 , 7/13 ,5/9,10/11
Step-by-step explanation:
5/9 , 7/13 , 2/7, and 10/11
5/9 = 0.555
7/13≅ 0.54
2/7 ≅0.29
10/11=0.90
ascending order means from least to greatest:
2/7 , 7/13 ,5/9,10/11
To simplify this fraction, multiply the entire fraction by the conjugate of the denominator. The conjugate of a square root and a number being added to it would be the number <em>subtracted </em>from the square root. In other words, the conjugate of 
would be
.
Applying that information to our fraction shown here, the conjugate of the denominator would be 
. We will multiply both the numerator and denominator of our original fraction by this expression to obtain our answer, as shown below.
Our answer is 
.
You start at 0 on the unit circle the cos of 0 =1, but at cos 0 there is no angle at all so there is no y value so at cos 0 y=0, 180 is the opposite direction of the starting point which is 0 so the x value of cos180= -1 but there is still no upward or downward angle ie.. y value. so the y value = 0 at 0 and 180. answer is 0
