What are period and amplitude for the function

Mathematics
1 answer:
sweet [91]3 years ago
5 0

Answer: Period: 4. Amplitude: 3

Step-by-step explanation: The period is how long it takes for one cycle of the function (one up and down). In this graph, one cycle ends at 4.

The amplitude is how far away the extremes of the graph are from the midline. This graph is a total of 6 units tall, making the amplitude 3. (I usually find total graph height and divide by 2.)

A spinner can land on either red, blue, green, or yellow (the wedges are the same size). you spin twice. what is the probability
melisa1 [442]
There are four (4) colors to choose from. The number of sample space is equal to 4. With the condition given in this item, the probability of landing on blue on the first spin is equal to 1/4. Similarly, the probability of landing on yellow on the second spin is 1/4. 

            P = (1/4)(1/4)
  
              P = 1/16

Answer: 1/16

The profit earned by selling a quantity of x + 2 of a product is given by the expression x4 − x3 − 24. What is the average profi
Agata [3.3K]

the profit is a polynomial function :
p(x) = x^4 − x^3 − 24
the average profit per unit of product sold is :
ap(x) = (x^4 − x^3 − 24)/(x+2)

now,
(-2) is an "obvious" zero of p(x)
therefore : p(x) is dividable by (x+2)
and
the long division of p(x) by (x+2) gives :

Answer:
ap(x) = x^3 - 3x^2 + 6x - 12

1. And the meeting house windows, blank and bare, / Gaze at him with a spectral glare.
This is a <em>couplet</em>. You can tell this because there are two lines, a couple, as indicated by the slash between the phrases, as well as the end words rhyming.
2. A glimmer, and then a gleam of light / He springs to the saddle, the bridle he turns / But lingers and gazes, till full on his sight / A second lamp in the belfry burns.
This excerpt, I believe, is meant to highlight the <em>end rhymes</em>. You see, in the first and third lines, the last words rhyme, and the second and fourth lines' last words rhyme.
3. ...the Mystic meeting...
Seeing as how this is so incredibly short, and both "mystic" and "meeting" start with an "m", it is safe to assume that this is meant to highlight an <em>alliteration</em>. An alliteration is when two or more words in a row start with the same letter. A famous alliteration is in the tongue twister, "she sells seashells by the sea shore."
4. ...like a sentinel's thread / The watchful night wind...
This is a <em>simile</em>. Both similes and metaphors compare one thing to something generally more abstract in order to describe it better. In order to tell if something is a simile or a metaphor is to look for the words "like" or "as," because those are used in similes, but not metaphors. Since this uses the word "like," it is safe to assume that this is a simile.
