Answer:
d
Step-by-step explanation:
Answer:
Explicit formula: a(n)=3n-6
Recursive formula: a(n)=-3+(n-1)3 <--
Step-by-step explanation:
a(n)=3n-6 where a(1)=3(1)-6=-3 and d=3
<u>Plug values into recursive formula:</u>
a(n)=a1+(n-1)d
a(n)=-3+(n-1)3
Answer:
-29
Step-by-step explanation:
-ab-ac
= -(-6)(2/3)-(-6)(-5.5)
=4-33
= -29
We need to find a cosine function:

The amplitude represents half the distance between the maximum and minimum values of the function and the period goes from the x-value of one peak to the x-value of the next one. Therefore:

Finally:

And y(4) is:
