Which of the following is an example of an iamb?

a. happy
b. silly
c. today
d. fly

The correct answer is C. Today

Explanation:

In poetry, an iamb refers to the rhythmic unit used to create verses, iambs are composed of one unstressed or non-accented syllable (short syllable) and one stressed or accented one (long syllable). This type of unit or metrical foot is one of the most commonly used in English poetry especially through iambic pentameter which combines five iambs or through trimester which is the combination of three iambs. Additionally, the use of iamb in poetry provides rhythm to the verses as the combination of unstressed and stressed syllables create a sound pattern. The previous information suggests the word that is an example of iamb is "Today" considering this word is composed by two syllables and the accent or stress in this word is on the second syllable which is also the longer syllable, therefore the word "Today" is composed of an unstressed syllable and one stressed syllable which fits with the definition of the iamb and therefore makes this word a perfect example of this type of metric unit.

Part A: Geometric Sequence

Part B:

Part C: a₈ = 512

Step-by-step explanation:

When we find the common ratio between the y-values (x-values are n inputs), we should see that we get r = 2. That means we have a geometric sequence.

Because we have a geometric sequence, our recursive formula is: . Simply plug in our known variables:

Now we need to find what y is when x = 8, so (I used explicit formula):

a₈ = 512
