Do you mean or
?
Use the formula where
is the amplitude,
is the phase shift,
is the vertical shift, and the period is
.
Assuming your first case is true, the amplitude would be , your period is
, and your midline/vertical shift is
.
Assuming your second case is true, everything but the vertical shift stays the same. It would be in this case.
Answer:
<u>There are 17 terms in the sequence</u>
Step-by-step explanation:
<u>Arithmetic Sequence </u>
An arithmetic sequence is a list of numbers with a definite pattern by which each term is calculated by adding or subtracting a constant number called common difference to the previous term. If n is the number of the term, then:
Where an is the nth term, a1 is the first term, and r is the common difference.
In the problem at hand, we are given the first term a1=13, the last term an=-23, and the common difference r=-2 1/4. Let's solve the equation for n:
We need to express r as an improper or proper fraction:
Substituting:
n=17
There are 17 terms in the sequence
