No that is an inverse variation, a direct variation must have a y that is directly proportional to x while the picture shows a y that is inversely proportional to x <span />
Answer:
Option 4
Step-by-step explanation:
Given:
Sinθ = ![\frac{15}{17}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B17%7D)
Since, cos2θ = 1 - 2sin²θ
cos2θ = ![1-2(\frac{15}{17})^2](https://tex.z-dn.net/?f=1-2%28%5Cfrac%7B15%7D%7B17%7D%29%5E2)
cos2θ = 1 - ![\frac{450}{289}](https://tex.z-dn.net/?f=%5Cfrac%7B450%7D%7B289%7D)
cos2θ = ![\frac{289-450}{289}](https://tex.z-dn.net/?f=%5Cfrac%7B289-450%7D%7B289%7D)
cos2θ = ![-\frac{161}{289}](https://tex.z-dn.net/?f=-%5Cfrac%7B161%7D%7B289%7D)
Therefore, Option 4 will be the answer.
