The 3rd option is correct....................
Answer:
x=18
Step-by-step explanation:
<u>Key skills needed: Arithmetic Sequences, Addition</u>
1) We have a sequence of 8,13,x
2) To find the number being added every time, we do 13-8. This is 5.
3) This means x would be 13+5
4) 13+5 is 18 so x is 18.

The correct answer is D 8.6602
Answer:
"![[x|x=\frac{k}{4}\pi]](https://tex.z-dn.net/?f=%5Bx%7Cx%3D%5Cfrac%7Bk%7D%7B4%7D%5Cpi%5D)
for every integer 
"
Step-by-step explanation:
The function has zeroes at the x-intercepts in the graph.
If you look at the graph from 0 to 
, you will see that the graph cuts the x-axis at 4 points.
They are at half of 
, which is 
, at , at half point between and , which is at 
, and at .
They are basically all multiples of .
Looking at the answer choices, the third choice is correct.
Plugging in k=1, k=2, k=3, and k=4 into the equation, we see that the zeroes are exactly what we saw. Also, the negative side of the function holds true as well.
Third answer choice is right.
If i understand the question correctly then the answer you are looking for is 9
