Answer:First three terms: 11,20,29 .

Step-by-step explanation:

Write a systems of equations. tn=a+(n−1)d. sn=n2 (2a+(n−1)d). So,. 110=11+(n−1)d 726=n2(22+(n−1)d).

I hope this is right

Answer:

B) $y=sin(x+\frac{\pi}{2})$

Step-by-step explanation:

Technically, since the function starts at its maximum, you could say the function is $y=cos(x)$ , but the answer choices all use sine instead. Therefore, we will have to use the cofunction identity $cos(x)=sin(x+\frac{\pi}{2})$ and we can see that the correct answer is B.
