We can times 5/2 and 9/2. And then divide that number with 21/2.
Then we can get 15/14.
We can subtract 15/14 from 11/2.
b=31/7
Answer:
Option (A)
Step-by-step explanation:
It has been given in this question that sign telling path has a 2% grade.
2% grade means a rise of 2 meters for a horizontal change of 100 m (As given in the figure attached).
All the trigonometric ratios for the angle θ between the path and the horizontal are,
Sinθ = 
Cosθ = 
tanθ = 
Since measures of the opposite side and adjacent sides are given
Therefore, tangent ratio will be applied to get the measure of the angle,
tanθ = 
θ = 
Option (A) will be the answer.

Answer:</h2>
This relation is a function because a function, in fact this is a linear function. We have that:
![\left[\begin{array}{cc}x & y\\2 & 3\\4 & 4\\6 & 5\\8 & 6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Dx%20%26%20y%5C%5C2%20%26%203%5C%5C4%20%26%204%5C%5C6%20%26%205%5C%5C8%20%26%206%5Cend%7Barray%7D%5Cright%5D)
As you can see below, all the points have been plotted an this is a linear function. Therefore, with two points we can get the equation, so:

Finally, the equation is:

The answer is d because the sequence is add two of the last term
6+2=8+2=10+2=12+2=14+2=16+2=18...
